- In this study, we initially generated two-dimensional histograms by utilizing mesoscale model grid point values (MSM-GPV) with approximately a 5km mesh and observational data to compare wind conditions in the coastal areas of Osaka Bay. We also investigated the correlation between MSM and wind direction and speed gauges installed at the mooring facilities or AMeDAS observation values. As a result, the characteristics of wind conditions at sea became more easily discernible. The prediction accuracy of MSM was high at observation points near the sea while the prediction accuracy at observation points installed on land tended to be low. We also found that the correlation between MSM and observation values varied significantly depending on wind direction. Based on these analytical results, we discussed the use of MSM for ship operation judgment and its predictive accuracy.Japan Institute of Navigation, Jul. 2024, 日本航海学会論文集(Web), 150, 21 - 26, Japanese[Refereed]
- In this study, we investigated the risk of large vessels encountering strong winds during berthing and unberthing using wind direction and speed data from The Automated Meteorological Data Acquisition System (AMeDAS) observations by the Japan Meteorological Agency and grid point values from the Meso-Scale Numerical Weather Prediction Model (MSM-GPV, approximately 5km resolution). An investigation of the maximum instantaneous wind speed values at AMeDAS observation points in Kobe, Kobe Airport, and Kansai International Airport in Osaka Bay revealed that the risk of encountering strong winds varies significantly with the wind direction and speed from MSM grid point values. When the wind speed at the MSM grid points near the observation points is 7-10 m/s, the risk of encountering strong winds is higher at observation points close to the land compared to those offshore. For example, at the Kobe AMeDAS observation point, the probability of the maximum instantaneous wind speed exceeding 15 m/s reaches 58% with an ENE wind direction. At the AMeDAS observation points in Kobe Airport and Kansai International Airport, the risk of encountering strong winds is high with the SSW wind direction, therefore there is the need to take caution with the winds from the SSW.Japan Institute of Navigation, 2024, 日本航海学会論文集(Web), 151, 64 - 70, Japanese[Refereed]

- Atmospheric pollutant concentrations have been higher around the Osaka Bay and Harima-Nada Sea, and surroundings than those in the other regions of Japan, and is pointed out to be influenced by shipping emissions. The spatio-temporal dynamics of atmospheric SO2, NOx, and PM2.5 were examined based on the ship onboard observations over the Seto inland sea and atmospheric monitoring data. The Conditional Bivariate Probability Function analysis for the Tarumi and Hyogo-nanbu sites showed the air mass inflow with higher SO2 from the Akashi Strait known as the congested sea area, and that was a different trend from the diurnal NO2 change characterized with two peaks. Meanwhile the daytime PM2.5 was increased in the warmer seasons but the diurnal change was lower than the SO2 and NOx cases, that implied the long-range PM2.5 pollution. Ship onboard SO2 concentrations in the maritime airmass were up to 5 times higher than those at the ground monitoring sites. On the other hand, NOx and PM2.5 in the maritime airmass were lower and the same levels when comparing those at the monitoring sites, respectively. These suggested that the major sources of SO2 and NOx existed on the sea and on the land areas, respectively.Japan Society for Atmospheric Environment, Feb. 2021, 大気環境学会誌(Web), 56(2) (2), 35 - 42, Japanese[Refereed]

- The inner part of Osaka Bay in Japan is affected by eutrophication, and the western part of the bay is affected by oligotrophic conditions. In this study, the distribution, sources, and decomposition rate of organic nitrogen (Org-N) in the estuarine region of Osaka Bay, defined as the region from the mouth of the Yodo River to the bay head, were studied to elucidate the cause of this uneven distribution of nutrients in the bay. Concentrations of Org-N are much higher in the estuary region than in freshwater areas or in the bay itself. Particulate organic nitrogen, which potentially sinks toward the bottom, accounted for 74 ± 11% of Org-N. The decomposition rate of dissolved organic nitrogen over 100 days, which is potentially supplied to the sea with low-salinity water, was 29 ± 4%. These results regarding the decomposition rate of organic matter in the estuarine region of Osaka Bay may improve the accuracy of models of the impact of land-sourced nutrient load on nutrient conditions in the bay.Japan Society on Water Environment, 2020, Journal of Japan Society on Water Environment, 43(3) (3), 87 - 96, Japanese[Refereed]Scientific journal

- Seasonal variation in nitrogen cycling at the upper layer of the Pasig River estuary in Manila Bay was calculated during January 1996 to December 1998 by using the numerical ecosystem model. Chl.a and DIN concentrations are relatively low, river discharge is small, and solar radiation is strong from March to May in dry season. The main reason of low chl.a concentration is that the solar radiation is too strong. On the other hand, as DIN concentration is relatively high and solar radiation is optimum, chl.a concentration is relatively high from August to December in rainy season. Main source of DIN in rainy season is the vertical transport from the lower layer due to the strong estuarine circulation.Lead, Indonesian Institute of Sciences, May 2018, Marine Research in Indonesia, 32(2) (2), 75 - 87Scientific journal

- This is the overview of productions by using the numerical ecosystem model which is the joint research of RIAM with Prof. T. Yanagi from 2002 to 2012. The numerical ecosystem model of box type was used for researches. The material cycling structure of Osaka Bay and Suo-nada differed depending on whether the river where discharge and material load are large exists. Year-to-year variation of dominant red tide species in the inner part of Osaka Bay in 1990s mainly depends on variation of physical environment and phosphorus supply. If material load from land to Manila Bay is nothing, phytoplankton concentration in Manila Bay will decrease 6%. Long-term effort is required like the Seto Inland Sea in order to improve environment of Manila Bay.Lead, Research Institute for Applied Mechanics, Kyushu University, Sep. 2013, 九州大学応用力学研究所所報, 145, 67 - 71, JapaneseResearch institution

- For the weather and sea states data used by the weather routing, the difference between the present condition and prediction and the permissible range on vessels operation were examined. The variation of data within 3 days from prediction is small. Moreover, even if it encounters different weather and sea states from prediction, it is in the permissible range in general. When five days or more will pass since prediction, the case which the gap from prediction of the position of low pressure or the high wave area exceeds the permissible range is more than 50%. Especially the gap of east-west direction is large.Japan Institute of Navigation, Mar. 2010, 日本航海学会論文集, 122(122) (122), 201 - 207, Japanese[Refereed]

- Occurrence number of red tides in Osaka Bay in Japan is more than 20 cases every year. Diatom red tide was dominant in Osaka Bay, but the non-diatom red tide was dominant in early 1990s. Therefore, the material cycling in Yodo River estuary in Osaka Bay during August from 1991 to 2000 was analyzed by using the numerical ecosystem model and field observation data to clarify the reasons of change in red tide species. Year-to-year variation in calculated concentration ratio of diatom to non-diatom corresponds to the variation in observed ratio of red tide days of diatom to non-diatom. Limiting nutrient of primary production is phosphate over the period. Diatom dominated from 1991 to 1993, but it was difficult for non-diatom to grow due to the limitation by physical condition. Non-diatom was able to grow because of good physical and nutrient conditions from 1994 to 1996. And diatom dominated again under the good physical condition, and phosphorus supply was not enough for non-diatom to grow from 1998 to 2000. Phosphate concentration in the lower layer of Yodo River estuary was important to the variation in red tide species in the upper layer of Yodo River estuary.Lead, Elsevier BV, Jan. 2008, Marine pollution bulletin, 57(1-5) (1-5), 103 - 7, English, International magazineScientific journal

- Year-to-year variations in the Yellow River discharge and the primary production in the Bohai Sea were investigated based on the river discharge data and satellite images of SeaWiFS from 1998 to 2005. The yearly averaged chlorophyll a concentration at the central part of the Bohai Sea was high in the year when the Yellow River discharge was large and low in the year when that was small. This is due to that phosphate concentration in the Bohai Sea depended on the Yellow River discharge.Interdisciplinary Graduate School of Engineering Sciences, Kyushu University, Jan. 2008, Engineering Sciences Reports, Kyushu University, 29(3) (3), 334 - 336, JapaneseResearch institution

- Recently, water quality of Manila Bay has been deteriorated and red tides frequently occur. The limiting nutrient of the primary production in Manila Bay is nitrogen. Therefore the nitrogen cycling in Manila Bay in dry and rainy seasons were calculated, and the calculation result that full TN was loaded from rivers was compared with the case of 1/2 loading. The primary production in rainy season is higher than in dry season because dissolved inorganic nitrogen (DIN) concentration is high. DIN is assimilated by phytoplankton, and phytoplankton is grazed by zooplankton and/or is moralized, and sank to the lower layer as dtritus. But detritus is back to the upper layer due to the vertical mixing. Because stratification is weak in dry season. The main source of DIN is decomposition in dry season. On the other hand, stratification and estuarine circulation is strong in rainy season. Therefore detritus sank to the lower layer, then DIN is regenerated in the lower layer and is transported to the upper layer due to the strong estuarine circulation. The residence time of TN (Total Nitrogen) in the upper layer in dry season is longer than in rainy season. Nitrogen is used slowly and many times in dry season. But nitrogen is sufficiently supplied, and is used quickly by primary production in rainy season. And also it flow out quickly by strong estuarine circulation. The reduction ratio of nitrogen concentration is only about 15%, when nitrogen loading from rivers is reduced to the half. Because decomposed DIN in Manila Bay is more than the loading DIN from rivers. Moreover, the reduction ratio of TN, especially organic matter in dry season is smaller. Because suspended solid in the lower layer is much and stratification in dry season is weak, so the suspended solid from the lower layer supports the material cycling of the upper layer in dry season.

There are many unclear points for N2O. In particular, Ocean is though to act reserve of N2O procreation and absorption generally. The observation of N2O concentration has not been carried out sufficiently and the exchange volume between the sea and the air has not been observed constantly. The one of the reason of it is that we have not standard measurement method of N2O concentration in the sea water. So, the detailed spatial and temporal observation is difficult now. So, we attempted the development of N2O concentration measurement system and the prototype was made. N2O measurement by the batch method has advantage that time is shorter and sample sea water is smaller. Measurement time in the system is about 30 minutes. Therefore, spatial distribution of N2O concentration in the sea by using a ship which has 10 knot speed will be obtained every about 10km. And, we measure N2O concentration in the air at the same time to obtain the direction of N2O flux between the sea and the air.神戸大学海事科学部, Jul. 2007, Review of the Faculty of Maritime Sciences, Kobe University, 4(4) (4), 33 - 38, JapaneseResearch institution

- The Tonankai and Nankai earthquake is said to occur 80-90% of the probability in 50 years. Height of tsunami by the earthquake is predicted more than 1.5m in the Port of Osaka. If many ships evacuate at once, they will be in panic in Osaka Bay. Here the Hazard Chart of Tsunami in Osaka bay is proposed for vessel evacuation in safety. Mutual vessels' distances and distance to shore line are estimated around 2,000m. According to statistical data about 110 vessels exist in Osaka Bay a day, the surface area of Osaka Bay has enough to evacuate all of those vessels. Some ban areas and the emergency tracks are designed in the Hazard Evacuation Chart for the dangerous cargo and the large commercial ships, and the Chart is designed for the general cargo ships and the small boats, respectively.Japan Institute of Navigation, Sep. 2006, 日本航海学会論文集, 115(115) (115), 177 - 182, Japanese[Refereed]
- Many maritime casualties occur in sea areas around Japan every year, and the loss of the human life and economy and the damage to the natural environment are so huge. In this report their relating weather and sea states are focused on and the quantitative characteristics of casualties in each sea area are examined based on the data for 20 years from 1980 to 1999 constructed from the judgment records of Japan Marine Accidents Inquiry Agency from 1980 to 2002. The sea around Japan is divided into 10 sea areas according to the characteristics of casualties and the geography. In the coastal sea around Hokkaido Island, the northern and central coastal seas of the North Pacific Ocean and Seto Inland Sea, many casualties were caused by poor and restricted visibility by fog. In the northern coastal sea of the Sea of Japan, many casualties were caused by strong wind, and in the southern coastal sea, many casualties were done by the high wave. In Seto Inland Sea and the western coastal sea of Kyushu Island, the percentage of casualties by ocean and tidal currents was higher than the other areas. In the northern and central coastal seas of the Pacific Ocean and Seto Inland sea, the percentages of casualties by cargo and tanker ships were high. In the southern coastal sea of the Sea of Japan, the percentage of the casualties by pleasure boats were higher than the other areas.Japan Institute of Navigation, Sep. 2006, 日本航海学会論文集, 115(115) (115), 169 - 176, Japanese[Refereed]
- Nitrous Oxide (N_2O) is one of the important gases of the green house gases. The average N_2O concentration of the global ocean is 320ppb. But it is not clear to the distribution of N_2O concentration in each place. We sampled the air continuously and measured N_2O concentration in the air during the navigation of the Seto Inland Sea and southern offshore of the Shikoku and Kyushu Island from 10th Sep 2005 until 16th. The average N_2O concentration of all the periods was 282ppb. The average N_2O concentration in the inland sea, Osaka Bay and the Seto Inland Sea and Kagoshima Bay, was 288ppb, and it in the open ocean, southern offshore of the Shikoku and Kyushu Island, was 256ppb. N_2O concentration in the inland sea is higher than that of the open ocean. The highest N_2O concentration area is Osaka Bay with 320ppb. When the wind blows from the urban area, N_2O concentration increases, and when the wind blows from the open ocean, N_2O concentration decreases.神戸大学海事科学部, Jul. 2006, Review OF the Faculty of Maritime Sciences, Kobe University, 3(3) (3), 33 - 40, JapaneseResearch institution
- The river discharge of the Yellow River has decreased from late half of 1980 due to the overuse of water on land. To clarify the relation between decreasing discharge of the Yellow River and bio-chemical environment of the estuary of the Yellow River, Chl.a, Dissolved Inorganic Nitrogen (DIN), Dissolved Inorganic Phosphorus (DIP) and Dissolved silicon data were collected from the previous reports. Chl.a concentration of Bohai Sea increased from 2000, and the limiting nutrient of primary production was change from nitrogen to phosphorous. DIP and DSi concentration of Bohai Sea decreased, because P and Si loading from the Yellow River decreased due to the decreasing discharge of the Yellow River. Si is more sensitive than P to the decreasing discharge of the river, because P is loaded artificially. DIN loading from the Yellow River decreased, but DIN concentration of Bohai Sea increased.神戸大学海事科学部, Jul. 2006, 神戸大学海事科学部紀要, 3(3) (3), 41 - 45, JapaneseResearch institution
- Nitrogen cycling in Manila Bay during dry and rainy seasonsThe nitrogen cycling was calculated in Manila Bay during dry and rainy seasons. The primary production in rainy season is higher than that in dry season. The main source of DIN (Dissolved Inorganic Nitrogen) is decomposition in dry season and the advective and diffusive flux from the lower layer in rainy season. River discharge and primary production are small in dry season, and the estuarine circulation is weak. The nitrogen cycling is closed in the upper layer in dry season. On the other hand, river discharge and primary production in rainy season are large. Therefore DIN is assimilated by phytoplankton, and phytoplankton is grazed by zooplankton and/or is moralized, and sank to the lower layer. DIN is regenerated in the lower layer, and is transported to the upper layer due to the strong estuarine circulation. Nitrogen cycling is closed in the upper and lower layers in rainy season. The residence time of TN (Total Nitrogen) in the upper layer in dry season is longer than that in rainy season. Nitrogen is used slowly and many times due to small nitrogen supply and weak estuarine circulation in dry season. But nitrogen is sufficiently supplied, is used quickly by primary production and is also quickly flowed out by strong estuarine circulation in rainy season.The University of Tokyo, Apr. 2006, Coastal Marine Science, 30(1) (1), 49 - 53, English[Refereed]Scientific journal
- Many maritime casualties occur in sea areas around Japan every year, and loss of the human life, economy and the damage to the natural environment are so huge. The causes of casualties are various. In this report their relating weather and sea states were focused on and characteristics of maritime casualties in each sea areas were examined in detail based on the data base for 20 years from 1980 to 1999 constructed from the judgment records of Japan Marine Accidents Inquiry Agency published from 1980 to 2002. These maritime casualties occurred in any sea areas around Japan, however many casualties occurred in the eastern and southern coasts of the mainland, the Seto Inland Sea, the northern and western coasts of Kyusyu Island, and the coast of Southwest Islands rather than the other sea areas. Moreover, many casualties relating to restricted visibility occurred in the similar sea areas. In Southwest Islands, many casualties relating to wind and wave occurred compared to the other weather and sea states. More detailed analytical results on the characteristics of weather and sea states in each sea area are reported in the paper.Japan Institute of Navigation, Mar. 2006, 日本航海学会論文集, 114(114) (114), 185 - 190, Japanese[Refereed]

- The oil-spill patterns in Osaka Bay area were considered by using the Oil-Spill Prediction Model, which has been developed by petroleum Associate of Japan. The simulated oil-spill patterns enables us to know the each contribution of driving factors of oil spill such as tidal current, tide-induced residual current and river-water driven flow. The oil-spill patterns are mainly determined by the force balance of wind and constant component of total current. The wind forces of over 6m/s wind speed control oil-spill patterns even at the strongest-current area in Osaka Bay. When we consider the contributions of wind forces separately from constant component of total current, the wind forces may influence on oil spill patterns greatly even the wind speeds are less than 1m/s.Japan Institute of Navigation, Sep. 2005, 日本航海学会論文集, 113(113) (113), 249 - 258, Japanese[Refereed]

- Environmental change is large in the Yodo River Estuary. In order to investigate a vertical and horizontal distributions of oceanic environment in the Yodo River Estuary, the current meter and the CTD (Conductivity, Temperature, Depth meter) were moored in the Yodo River Estuary from 29th June to 14th July for 16 days, and current direction and velocity, water temperature, salinity, etc, were observed continuously. Moreover water temperatures, salinity, etc, were observed around mooring CTD, and water and air were sampled and analyzed every day. We corrected the data and made the data set to consider oceanic environmental change in the Yodo River Estuary.神戸大学海事科学部, Apr. 2005, 神戸大学海事科学部紀要, 2(2) (2), 115 - 126, JapaneseResearch institution

- In the weather ship's routing, it is very important to take account of the permission of the encountered wind speed and wave height and functionize them in weather ship's routing simulation models. To clarify the navigators' permission of encountered maximum wind speed and wave height in the ship's routing simulation, the questionnaire and the routing simulation were made to navigators of ripe experience. According to the questionnaire, for the safety navigation the permission of the maximum wind speed was the Gale rank in the Beaufort wind scale. Navigators had two permission of the maximum wave heights of 5 to 8m and 10 to 12m. From the results of the weather routing simulation by navigators using the optimum weather routing soft ware, for the safety navigation the encountered maximum wind speed and wave height were 30 to 40 knots and 7m at against winds and waves, 30 knots and 5 to 8m at lateral winds and waves, and 40 knots and 11m at following winds and waves, respectively.Japan Institute of Navigation, Nov. 2003, 日本航海学会論文集, 110(110) (110), 27 - 35, Japanese[Refereed]

- Nitrogen cycling in Suo-Nada is analyzed using a numerical ecosystem model that consists of upper and lower layers separated by a pycnocline. Primary production is higher in autumn and spring compared to those in other seasons, and lowest in winter. In spring, primary production in the lower layer is comparable to that in the upper layer. The main path of nitrogen cycling is DIN (Dissolved Inorganic Nitrogen) → phytoplankton → detritus → DIN. The decomposition rate from DON (Dissolved Organic Nitrogen) to DIN increases in the season with smaller primary production. Because the DIN supplies from the land and the lower layer are small, nutrient is depleted in the upper layer during spring to summer. Therefore the primary production in the upper layer is mainly limited by DIN. Furthermore, since the outflow flux of nitrogen is small, DIN is mainly supplied by the decomposition, and mostly consumed by primary production. In the lower layer, DIN is also mainly supplied by decomposition, and light intensity is more critical for primary production than DIN concentration. The inner part of Osaka Bay is a highly eutrophicated area, characterized by large outflow flux compared to sedimentation flux. In contrast, outflow flux in Suo-Nada is relatively small to sedimentation flux, since Suo-Nada has relatively weak estuarine circulation. These results suggest that if the nutrient load from land to Suo-Nada would increase, the environment of Suo-Nada would become worse, for instance, red tide area would expands, and it would take a longer time to recover than Osaka Bay.The Oceanographic Society of Japan, Nov. 2002, 海の研究, 11(6) (6), 591 - 611, Japanese[Refereed]

- Phosphorus cycling in the inner part of Osaka Bay is analyzed using a numerical ecosystem model which consists of euphotic and aphotic layers. Since the accuracy of this model is ± 62% except for POP in the aphotic layer, it is useful to discuss the characteristics of phosphorus cycling and lower trophic level ecosystem in the inner part of Osaka Bay. The main path of phosphorus cycling in the euphotic layer is DIP → phytoplankton → detritus→ DOP → DIE, or detritus → DIP. DIP in the euphotic layer is mainly supplied by decomposition of DOP and detritus (49% of total supply on annual average). Decomposition is controlled by water temperature. DIP transport from the aphotic layer to the euphotic layer (24% of total supply on annual average) is almost equal to DIP supply from rivers and rain (27% of total supply on annual average). The most effective limiting factors on primary production are DIP concentration in summer and water temperature in winter.The Oceanographic Society of Japan, May 2001, 海の研究, 10(3) (3), 203 - 217, Japanese[Refereed]
- The doppler radar observation was made to examine the relationship between ocean waves and radar sea echo signals and to obtain the information of ocean waves from those sea echo signals in Ishikari and Wakasa Bays in winters of 1991-1992 and 1997-1998, respectively. The doppler wave direction is defined here as a direction in which the maximum doppler shift of sea echo signals occurs, and the doppler wave speed is also done as a doppler speed on that doppler wave direction. It was found out that the doppler wave direction and speed were not related with the direction and speed of winds and currents. The doppler wave direction agreed with the observed wave direction within two points in the 16-point direction system. The doppler wave speed was proportional well to the phase speed estimated from the observed wave period with the 1/5 to 1/4 slope. It is concluded that the doppler shift of the sea echo signals is mainly caused by the wave propagation rather than winds and currents.Japan Institute of Navigation, 2001, The Journal of Japan Institute of Navigation, 105, 97 - 102, Japanese

- The observation was made to examine the relationship between the sea state and radar sea echo signals and to obtain information and the characteristics of the sea state from the signals by the doppler radar in Otaru Bay, Hokkaido for 49 days in total from the 14th of December, 1991 to the 31st of January, 1992. Here, the doppler direction is defined as a direction in which the maximum doppler shift of radar sea echo signals occurs, and the doppler speed of the signals is also done as an average doppler speed on that doppler direction. It was found out that the doppler direction and speed were not related with the direction and speed of winds and currents, but related strongly and agreed so well with the propagating direction and phase speed of waves, respectively. The doppler speed is proportional to the phase speed of the significant waves estimated from the observed wave period with the 1/10 to 1/3 slope. It is concluded that the doppler shift of the radar sea echo signals is mainly caused by the wave propagation even though it might be slightly effected by winds and currents.Japan Institute of Navigation, Sep. 2000, 日本航海学会論文集, 103(103) (103), 17 - 22, Japanese[Refereed]

- On the basis of the field observations of water quality characteristics of Southern Iyo-Nada and Osaka Bai in the Seto Inland Sea by Shikoku Electric Power Co., Inc. and Osaka Prefectural Fisheries Experimental Station from 1980's to 1990's, the seasonal and year-to-year variations of DIN, DIP, and DIN/DIP and nitrogen and phosphorus cycling are discussed. The situation of Southern Iyo-Nada is oligotrophic (DIN concentration is less than 4.1 μM, DIP concentration is less than 0.22 μM on annual average) throughout the year from 1982 to 1998. There was no significant seasonal variation in N/P ratio. Nutrient concentrations in the bottom layer in August were higher than those in the surface layer by 1.7 μM for DIN and 0.14 μM for DIP. It is suggested that nutrients in Southern Iyo-Nada mainly come from the continental shelf. Osaka Bay was eutrophic through the year from 1980's to 1990's (DIN concentration was more than 11.5 μM, and DIP concentration was more than 0.48 μM on annual average), and there was no year-to-year variation in DIN concentration and DIN/DIP. The decreasing tendency of DIP concentration since 1973 stopped in 1985, and since then it has been stable. DIN concentration in the surface layer was higher than that in the bottom layer by 5.6 μM on annual average, because DIN was supplied from rivers. DIP supplied by DIP release from the bottom sediments in summer. Not only nutrients supply from the river but also DIP release from sediments in summer affect nutrients cycling in Osaka Bay. Therefore primary Production in Osaka Bay in February and May is limited by phosphorus, but a shortage of phosphorus is canceled in November due to high DIP release from sediments.The Oceanographic Society of Japan, May 2000, 海の研究, 9(3) (3), 133 - 142, Japanese[Refereed]
- On the basis of the field observations of water quality characteristics of the Seto Inland Sea by Hashimoto et al. (1996), the seasonal variations in standing stocks of DIN, PON, DIP, POP and Si, and the characteristics of lower trophic level ecosystem in the Seto Inland Sea are discussed. The standing stock ratios of DIP, DOP, and POP are almost same, about 30%, on annual average. Primary production is generally limited by DIP in the eastern part of the Seto Inland Sea, and by DIN in the western part.The Oceanographic Society of Japan, Mar. 2000, 海の研究, 9(2) (2), 83 - 89, Japanese[Refereed]

- The wave observation by a marine radar has been made 30 days in total for 3 years from 1991 to 1993 at the west coast of the Awaji Island. In 11-run observations, the wave directions and wavelengths of prevailing waves could be obtained from the data of radar sea clutter. The wave directions and wavelengths obtained by the 2-dimensional spectral analysis were not different from visually observed wave directions by 7 degrees and estimated wavelengths by 6m, respectively. The results of the directional 1-dimensional spectral analysis were also reasonably consistent with them of the visual observation and the 2-dimensional spectral analysis. Although the results of the directional 1-dimensional spectral analysis were less than them of the 2-dimensional spectral analysis in accuracy, the method of the directional 1-dimensional spectral analysis is useful in the automatic selection of the analyzing area for the 2-dimensional spectral analysis in the wave analysis system.Japan Institute of Navigation, Mar. 1994, 日本航海学会論文集, 90(23-31) (23-31), 23 - 31, Japanese[Refereed]
- The behavior of CO2 in coastal seas has been less extensively studied than in open oceans. In this study, we examined the spatial characteristics of pCO2 (partial pressure of CO2 in seawater) based on measurements taken from the Seto Inland Sea, with a focus on regional characteristics. Across all regions, pCO2 levels were lower in spring than in summer, with an average difference exceeding 100 µatm, suggesting sea temperature-related influences. During summer, pCO2 characteristics varied between the strait and non-strait regions. In Osaka Bay, pCO2 was consistently lower during both seasons, likely due to considerable CO2 uptake driven by high primary production. In most straits, summer pCO2 levels were higher than in adjacent non-strait regions, with an average difference of approximately 64 µatm. This suggests that high-pCO2 water masses, formed through organic matter decomposition in the lower stratified layers flowed horizontally into nearby straits and were subsequently transported to the surface through vertical mixing. In spring, CO2 was absorbed across all regions, whereas in summer, most regions of the Seto Inland Sea experienced CO2 emission. The interconnected structure between the straits and Bay-Nada areas contributes to seasonal variations in CO2 absorption and emission.The Oceanographic Society of Japan, 15 Nov. 2024, 海の研究, 33(5/6) (5/6), 77 - 87, Japanese

- A tsunami induced by the Nankai Trough earthquake may disturb marine sediments in the inner part of Osaka Bay. Since nutrient release from marine sediments has a significant impact on nu-trient concentrations in seawater, an incubation experiment was conducted to estimate the release rates of NH4-N and PO4-P in order to understand the present rates and to quantify the changes in the rates caused by tsunamis in Osaka Bay. The current release rate of NH4-N is an extension of the decreasing trend since 2000. The PO4-P release rate has remained at a low level since 2008. The release rate of redeposited sediments after exposure to the aerobic environment caused by a tsunami may decrease to approximately 70% of the current level for NH4-N and 60% for PO4-P. Nutrient concentrations and fishing have begun to decline in Osaka Bay. A reduction in the nutrient release rate by tsunamis may further limit primary production under the current situation where the contribution of release to nutrients in seawater is significant.MDPI, Jun. 2023, Water, 15(11) (11), 2041, English
- In this study, we analyzed AMeDAS wind data from five Japan Meteorological Agency’s stations and discussed the wind speed and gust factor for each wind direction. The gust factor was larger on land than on the sea, and the correlation between wind speed and gust factor tended to be higher on the sea. As a result of the investigation, there was a case with a maximum instantaneous wind speed of 16m/s and a gust factor of 2.86. This gust was conspicuously caused by the passage of a front with strong rainfall intensity. At Kobe and Kansai International Airport, it was found that the winds became stronger when the wind direction changed from SSE to SSW, and marine accidents had occurred due to this phenomenon. These findings can be used to make operational decisions and help prevent maritime accidents.Japan Institute of Navigation, 2023, The Journal of Japan Institute of Navigation, 148, 58 - 64, Japanese

- Diesel engines are used as the main power source of marine transport and the continuous improvement of their performance offers better specific fuel oil consumption (SFOC). From the standpoint of Carbon Dioxide (CO2) emission, marine engines are environment friendly compared to those used in land transportation and other industries. Attention should be focused only on CO2 emissions but also on other greenhouse gases (GHG), such as Nitrous Oxide (N2O), which is the result of a reaction between nitrogen and sulfur components of low-grade fuels.The Japan Institute of Marine Engineering, Sep. 2013, Marine Engineering, 48(5) (5), 692 - 698, Japanese
N2O is known as the third major GHG following CO2 and methane (CH4). The global warming potential (GWP) of N2O is 310 times as large as that of CO2 because N2O in the atmosphere is very stable, and it becomes a source of secondary contamination after photo-degradation in the stratosphere. N2O concentration 1800 years before was less than 280 ppb, but in the last 200 years it has increased rapidly. Since N2O emission from natural sources is very difficult to control, discussions on N2O emission reductions should be centered on artificial N2O which represents 35% of the total N2O emissions. To argue this point, it should be noted that there are some reports on the N2O exhaust characteristics from stationary power plants and land transportations, but those of marine transportations are very limited.
In this experimental study, the authors investigated N2O emission characteristics of an actual ship at the sea, and examined relationships between N2O and other gaseous emissions. The experimental results showed that N2O emission exhibited different characteristics compared with NO which makes up over 80 percent in NOX, and had exhaust characteristic very similar to SO2 emission. But when based on the excess air ratio, the difference between these two species increased with decreasing excess air ratio.[Refereed] - 神戸大学, Jul. 2013, 神戸大学大学院海事科学研究科紀要, 10, 33 - 44, Japanese神戸大学深江キャンパスにおける海洋・気象観測(2012年1月〜12月)

- Database of Maritime Casualties Relating Weather and Sea States.Many maritime casualties occur in sea areas around Japan every year, and the loss of the human life and economy and the damage to the natural environment are so huge. The causes of casualties are various. But, in this report their relating weather and sea states were focused on and the construction of the data base for 24 years from 1980 to 2003 was reported. The data base was constructed based on the judgment records of Japan Marine Accidents Inquiry Agency published from 1980 to 2004. The total number of constructed datasets is 1729. The data base consists of the date and time, place, information of ships, maritime traffic conditions, weather and sea states, causes, and so on.Yuge National College of Maritime Technology, 26 Feb. 2010, 弓削商船高等専門学校紀要, 32(32) (32), 31 - 34, Japanese
- A submarine groundwater discharge was estimated by water and salt budget analysis based on hydrographical observations offshore of Omae Beach, Osaka Bay, Japan. Those observations were carried out from August 23 to 23 2006. The estimated submarine groundwater discharge and through-flow on the boundary sections were compared with observed submarine groundwater discharge and current speeds as well as with the results of tidal current simulation by POM. The difference between variations in water volume estimated by the observed water level and the calculated result was less than 0.3%. Estimated through-flows on the boundary section qualitatively agreed with the results of the tidal current simulation. Estimated submarine groundwater discharge was 5 times the observed discharge. This will be recognized when various factors are considered. This method is available for estimating the submarine groundwater discharge over an entire target area. The water budget of this area during the period studied was dominated by the through-flow. Sea water continuously flowed in from the southern boundary, influenced by not only the tidal current but also by the residual current. An outflow that corresponded to a tidal change was observed in the eastern boundary. The contribution of submarine groundwater discharge to volume variations in the area was estimated at 5 to 8%.The Japanese Society of Limnology, 2009, Japanese Journal of Limnology (Rikusuigaku Zasshi), 70(2) (2), 117 - 128, Japanese

- A-06 Particulate associated and free-living denitrifiers in the seawater samples at microalgal blooming : Comparison of Nitrous Oxide Reductase Genes (nosZ)(AQUATIC ECOSYSTEM,(2) Oral presentation)We have studied the eco-physiology of denrtrifiers in marine habitats, especially in seawater columns where N_2O accumulation is sometimes observed. Based on some observations, which relate the increase of denitrifying bacteria and the occurrence of high N_2O seawater mass with the algal blooming, we make the hypothesis that the bacteria can denitrify in the anaerobic microhabitat around particles derived from algal cells. In this study, we enumerated denitrifying bacteria in two fractions, particle-associated and free-living, of the seawater, where diatoms were blooming, and analyzed the diversity ofnosZ (N_2O reductase gene) in each fraction. From the result, we concluded that unique denitrifiers, different from free-living ones, were living in association with particules, but the number of those were not so many comparing with free-living denitrifiers.Japanese Society of Microbial Ecology, 30 Oct. 2005, 日本微生物生態学会講演要旨集, (21) (21), 202 - 202, Japanese

- The Wave Observation by the Doppler Radar-I : Observations in Ishikari and Wakasa BaysThe doppler radar observation was made to examine the relationship between ocean waves and radar sea echo signals and to obtain the information of ocean waves from those sea echo signals in Ishikari and Wakasa Bays in winters of 1991-1992 and 1997-1998, respectively. The doppler wave direction is defined here as a direction in which the maximum doppler shift of sea echo signals occurs, and the doppler wave speed is also done as a doppler speed on that doppler wave direction. It was found out that the doppler wave direction and speed were not related with the direction and speed of winds and currents. The doppler wave direction agreed with the observed wave direction within two points in the 16-point direction system. The doppler wave speed was proportional well to the phase speed estimated from the observed wave period with the 1/5 to 1/4 slope. It is concluded that the doppler shift of the sea echo signals is mainly caused by the wave propagation rather than winds and currents.Japan Institute of Navigation, Sep. 2001, 日本航海学会論文集, (105) (105), 97 - 102, Japanese[Refereed]

- Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (C), Kobe University, 2011 - 2013, Principal investigatorIn this experimental study, the authors investigated N2O emission characteristics of an actual ship at the sea, and examined relationships between N2O and other gaseous emissions. The experimental results showed that N2O emission exhibited different characteristics compared with NO which makes up over 80 percent in NOX, and had exhaust characteristic very similar to SO2 emission. But when based on the excess air ratio, the difference between these two species increased with decreasing excess air ratio.Competitive research funding
- Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (B), 2007 - 2009This study has been carried out for the investigation of minimization of ship disasters when tsunamis attach bay and coastal areas. First, basic ship navigation and mooring data were obtained by AIS(Automatic Identification System) for the evacuation analysis from the tsunami attack. Then we developed ship simulation programs for ship evacuation from tsunami attack. It is found that most ships in Bisanseto area can evacuate safely to the shelter areas by use of the program. Moreover, evacuation guidelines for an LNG ship, which is representative of a hazardous cargo carrier, were considered for the case of the ship entering the port. It is possible that the ship may encounter the first tsunami event in the case that the ship begins to evacuate from an inbound mooring direction. However, in the case where the ship is moored in the outbound direction and is oriented toward the open ocean, it is likely to overcome the potential threat of the first tsunami event. In addition above, we have developed ship motion analysis programs suitable for inter moored and/or connected ships under tsunami attack external forces. Using this system it is possible to evaluate whether those moored ships can ensure the tsunami attack. Above mentioned programs can evaluate several complex ship situations under tsumai attackCompetitive research funding

And based on the results of those on-board observations, related observations and experiments, "The analysis of marine plankton, bacteria and germ", "the hydraulic experiment of the ballast water tank", “the development research of the ballast water disposal technique using shack waves" were conducted. The main research items are following below. (1) Information and movements related on the international regulation and treaty on ballast water disposal and management methods were collected. (2) The hydraulic experiment of the ballast water tank and three dimensional numerical simulation experiment were conducted. And the situations of the ballast water circulation and exchange and its effectiveness were clarified. (3) The basic development research on the inactivation technique of marine bacteria using shock waves generated by a compressed air gun and the micro bubble collapse were conducted. And the characteristics and the effectiveness were clarified. (4) Analyses of marine plankton, bacteria and germ in the sediments of the ballast water tank were conducted. And those characteristics were clarified. (5) Observations of the marine biological activity condition by the satellite in the ballast water exchange ocean area and the marine chemical and production structure in the ballast water intake coastal sea area were conducted. And those characteristics were clarified. In 2008 too, the development research of the ballast water disposal technique using shock waves and the DNA analysis of plankton will be continued.Competitive research funding

However a ship anchored or moored in a harbor is pitched and rolled by a long period gravity wave (for period dozens of seconds, several minutes), it's countermeasure cannot be still enough, and now some problems on a mooring line strength and cargo handling work are still remained. Such a long period wave (for the amplitude is less than dozens of cm, a period, about dozens of seconds, several minutes) that is propagated from the open sea and coastal waters area includes the following problems. (1) A strong detachment and early flow are caused in harbor mouth neighborhood by long water particle exercise orbit of a long period surge, and they cause a harbor burying by drifting sand of bottom of the sea. (2) By a strong detachment and early flow near harbor mouth, it causes a serious and security problem on a ship navigating a narrow area near harbor mouth. (3) Wave energy of a long period gravity wave has a small propagation and reflection decrement, and after incidence to a harbor a greater part of the wave energy is kept and it may grow in the case of resonance with the harbor inherent frequency. Then a dangerous pitching and rolling movements for a mooring or anchoring ship in the harbor are caused by it. These serious problems for harbor design and the anchorage in a harbor caused by such a long period wave is beginning to examine. There development of a study for a long period wave is expected immediately, because the cause and characteristics of a long period wave are not made clear yet. In particular it is appear that a study to make clear the causes and the characteristics of a long period gravity wave on the basis of an observation fact is important. However it is difficult that the measurement is done by conventional wave observation technology, because a period of the long period gravity wave is too long and amplitude of it is too small compared with a normal gravity wave. Therefore in this research arrayed wave observation buoys system whose 3 dimensional movements are measured precisely by the Carrier-Phase Differential GPS is proposed. In this proposed system, a wind wave direction which is observed in before Cloverleaf-Buoy and a 3 dimensional wave information of a long period wave are measured precisely. And an evaluation of effectiveness was carried out by the experiment on land and some computer simulations. As using this proposed system, it made clear the cause and characteristics of a long period gravity wave and solve some problems about a ship's mooring and anchoring or harbor design. In near future, we will be able to clear the characteristics of the long period gravity wave and some problems about safety of port and mooring ship according to the long period gravity wave with the use of our proposed GPS Measurement System.
