Gamma A is a widespread non-cyanobacterial diazotroph and plays a crucial role for marine ecosystems, but its controlling factors are still largely unknown. This study, for the first time, quantified microzooplankton grazing on Gamma A and revealed significance of grazing pressure on Gamma A distribution around the Kuroshio region. It highlights the importance of top-down controls on Gamma A abundance and the associated nitrogen cycle.

Carbon and nitrogen are essential elements for organisms; their stable isotope ratios (13C : 12C, 15N : 14N) are useful tools for understanding turnover and movement in the ocean. In the Sea of Japan, the environment is rapidly being altered by human activities. The 13C : 12C of small organic particles is increased by active carbon fixation, and phytoplankton growth increases the values. The 15N : 14N variations suggest that nitrates from many sources contribute to organic production.

Short summary
The Sea of Japan, surrounding Russia, the Korean Peninsula, and the Japanese Archipelago, is one of the most rapidly changing seas in the world. We measured carbon and nitrogen isotope ratios of zooplankton. We determined that the carbon stable isotope ratio has been decreasing over 15 years, and this trend was comparable to or slightly more rapid than the Suess effect, which is a signal of anthropogenic disturbance. Therefore, carbon dynamics are changing in the shallow coastal waters.

Short summary
We investigated the nutrient assimilation characteristics of deep-water-induced phytoplankton blooms across the subtropical North and South Pacific Ocean. Nutrient drawdown ratios of dissolved inorganic nitrogen to phosphate were anomalously low in the western North Pacific, likely due to the high phosphate uptake capability of low-phosphate-adapted phytoplankton. The anomalous phosphate uptake might influence the maintenance of chronic phosphate depletion in the western North Pacific.

A full-depth-rated conductivity–temperature–depth profiler with
carousel~multiple sampling (CTD-CMS) system on the research vessel R/V Kaimei can illuminate the last frontier, i.e., the hadal zone, an oceanographic province deeper than 7000 m. A series of biogeochemical observations of hadal seawater at the Izu–Ogasawara and Mariana trenches revealed basically well-mixed hydrographic properties and a heterogeneous distribution of likely sediment-derived compounds.

The high abundance of Trichodesmium and active nitrogen fixation in the Kuroshio were not explained by the nutrient (nitrate, phosphate, and iron) distribution. We observed a Trichodesmium bloom and high nitrogen fixation near islands situated along the Kuroshio. Numerical particle-tracking experiments simulated the transportation of water around the Ryukyu Islands to the Kuroshio. Our results indicate that Trichodesmium growing around the Ryukyu Islands could be advected into the Kuroshio.

Short summary
We examined zooplankton community structure along the Japanese coast of the Japan Sea. Zooplankton were collected during 15 cruises in May from 1999 to 2013 by a plankton net. Species were identified under a microscope and were counted. The zooplankton community changed with water temperature and the coastal current, and the submarine canyon structure in this sea makes a difference in the zooplankton community.
