Hydrogen and carbon isotope ratios of methane as well as the relevant biogeochemical parameters and microbial community compositions in hydrothermal plumes in the Okinawa Trough were observed. We succeeded in simultaneously determining hydrogen and carbon isotope fractionation factors associated with aerobic oxidation of methane in seawater (εH = 49.4 ± 5.0 ‰, εC = 5.2 ± 0.4 ‰) – the former being the first of its kind ever reported.

The Synthesis Product for Ocean Time Series (SPOTS) is a novel achievement expanding and complementing the biogeochemical data landscape by providing consistent and high-quality biogeochemical time-series data from 12 ship-based fixed time-series programs. SPOTS covers multiple unique marine environments and time-series ranges, including data from 1983 to 2021. All in all, it facilitates a variety of applications that benefit from the collective value of biogeochemical time-series observations.

In this paper, we present the first edition of a global database compiling previously published and unpublished measurements of dissolved organic matter (DOM) collected in coastal waters (CoastDOM v1). Overall, the CoastDOM v1 dataset will be useful to identify global spatial and temporal patterns and to facilitate reuse in studies aimed at better characterizing local biogeochemical processes and identifying a baseline for modelling future changes in coastal waters.

We carried out parallel year-round observations of pH and related parameters in five stations around the Japan coast. It was found that short-term acidified situations with Omega_ar less than 1.5 occurred at four of five stations. Most of such short-term acidified events were related to the short-term low salinity event, and the extent of short-term pH drawdown at high freshwater input was positively correlated with the nutrient concentration of the main rivers that flow into the coastal area.

This is the first study of the current and future impacts of climate change on Pacific oyster farming in Japan. Future coastal warming and acidification may affect oyster larvae as a result of longer exposure to lower-pH waters. A prolonged spawning period may harm oyster processing by shortening the shipping period and reducing oyster quality. To minimize impacts on Pacific oyster farming, in addition to mitigation measures, local adaptation measures may be required.

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.

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.

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.

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.

Recent variation in air–sea CO2 flux in the Arctic Ocean is focused. In order to understand the relation between sea ice retreat and CO2 chemistry, we conducted hydrographic observations in the Arctic Ocean in 2013. There were relatively high pCO2 surface layer and low pCO2 subsurface layer in the Canada Basin. The former was due to near-equilibration with the atmosphere and the latter primary production. Both were unlikely mixed by disturbance as large sea-ice melt formed strong stratification.

The current study provides the first quantitative budget analysis of radiocesium re-suspended from ground surface contaminated by the Fukushima nuclear accident. It provides useful information to society since our simulation can be used for the long-term assessment of internal exposure to residents in Japan. It also discussed that the re-suspension from forest ecosystems could be a dominant source of suspended radiocesium in the warm season in Japan.

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
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.
