Distribution and seasonal variation of phosphorus in Tokyo Bay
Journal of Oceanography - Tập 42 - Trang 241-254 - 1986
Phosphorus dynamics in Tokyo Bay waters were investigated along with other oceanographic variables. Seasonal variations of dissolved inorganic phosphorus (DIP) and particulate phosphorus (PP) are inversely correlated with each other, and reflect variation in biological activity. A high concentration of PP in summer surface waters is caused by high primary production. The PP settled in the deeper l......
Circulation pattern and current variations with respect to tidal frequency in the sea near the head of Suruga Bay
Journal of Oceanography - Tập 37 - Trang 149-159 - 1981
Current measurements were conducted 10 m below the sea surface near the head of Suruga Bay intermittently from 1970 to 1978. The circulation pattern is usually counterclockwise; northward along the east coast (off Heda and at the mouth of Uchiura Inlet), westward along the north coast (off Fuji), and southwestward along the west coast (off Shimizu). The amplitudes of the four major tidal constitue......
Iron, manganese and aluminum in upper waters of the western South Pacific Ocean and its adjacent seas
Journal of Oceanography - Tập 64 - Trang 233-245 - 2008
Total dissolvable iron, manganese and aluminum distributions in upper waters were determined in the western South Pacific, Solomon Sea, Coral Sea, and Tasman Sea. In these oceanic regions, the surface aluminum distributions well reflect the atmospheric deposition pattern of mineral dust in the western South Pacific reported previously. Surface manganese distributions derive mainly from lateral tra......
Sudden strong current generated by an eddy in the eastern part of Wakasa Bay, Japan
Journal of Oceanography - Tập 73 - Trang 181-192 - 2016
A sudden strong coastal current called a “kyucho” occurred in August 2013 in the eastern coastal waters of Wakasa Bay, Japan. This study examined its characteristics based on both observational data collected by intensive field investigations and the simulation results of a numerical model. The field investigations comprised moored buoy observations near the coast and voyages by a research vessels......
Seasonal dynamics of the phytoplankton community in Sendai Bay, northern Japan

Interannual variations of the Hawaiian Lee Countercurrent induced by potential vorticity variability in the subsurface
Journal of Oceanography - Tập 68 - Trang 93-111 - 2011
Interannual variations of the Hawaiian Lee Countercurrent (HLCC) in the 2000s were investigated using satellite and Argo profiling float observations. The satellite-observed sea surface height shows that the geostrophic eastward current was anomalously strong to the west away from Hawaii in 2003 and 2005. However, the trade winds and the orographic wind curl dipole in the lee of Hawaii that drives......
Flushing rate and salinity may control the blooms of the toxic dinoflagellate Alexandrium tamarense in a river/estuary in Osaka Bay, Japan
Journal of Oceanography - Tập 69 - Trang 727-736 - 2013
The first observation of a red tide of the toxic dinoflagellate Alexandrium tamarense in the Yodo River estuary, Osaka Bay, Japan was in the spring of 2007. To clarify which environmental factors controlled the abundance of A. tamarense, field surveys were conducted in 2008 and 2009. In 2008, the increase of A. tamarense occurred from early to mid-March and temperatures ranged from 9 to 13 °C. In ......
The effect of background flow shear on the topographic Rossby wave
Journal of Oceanography - Tập 76 - Trang 307-315 - 2020
Due to the ubiquitous steep continental shelf slope in the East China Sea, topographic Rossby waves are very common when the Kuroshio Current flows along the slope, and of great importance in the water and energy exchange between the open ocean and coastal sea. To examine the structural characteristics of topographic Rossby wave, we use stretching transform of time and space and perturbation metho......
Space–time variations of sea ice in Bohai Sea in the winter of 2009–2010 simulated with a coupled ocean and ice model
Journal of Oceanography - Tập 77 - Trang 243-258 - 2020
Sea ice variations in the severe winter of 2009–2010 in the Bohai Sea are simulated with a coupled ocean and ice model. The modelled ice coverage shows good agreement with satellite observations. Integrated over three sub-regions [the extended Liaodong Bay (LDB), Bohai Bay, and Laizhou Bay], the temporal variations of ice volume and surface air temperature are well correlated at time scales of 5–1......
Spatial and temporal distributions of water temperature in aSargassum forest
Journal of Oceanography - Tập 38 - Trang 63-72 - 1982
The present study examined the influence of aSargassum forest on the spatial and temporal distributions of water temperature in a small cove on a time scale of the order of hours. Water temperature and algal density were measured along a fixed transect at the cove for almost 2 days. The measurements were carried out in May 1977 during the season of luxuriant seaweed growth, and in August during th......
