Ocean eddy is a closed circulation system having a vortex that creates a closed flow. These eddies vary in size from a few centimeters to a few hundreds of kilometers and can lead to changing in sea surface level, sea surface temperature, and nutrient concentration, which can be used to detect eddies using various satellite sensors. Thus, such a vo...

The long-term surface warming trend in the East Sea (Japan Sea; ES hereafter) stalled from 2000 to 2014 (−0.05°C yr⁻¹, surface warming slowdown), while the subsurface (100–300°m) warming trend continued (+0.03°C yr⁻¹). To address the processes underlying these contrasting trends in surface and subsurface temperature change, the trends in sea-level...

The mixed layer depth (MLD) is generally estimated using in situ or model data. However, MLD analyses have limitations due to the sparse resolution of the observed data. Therefore, this study reconstructs three-dimensional (3D) ocean thermal structures using only satellite sea surface measurements for a higher spatial and longer temporal resolution...

Solar radiation, particularly ultraviolet radiation (UVR, 280–400 nm), is known to play a significant role in driving primary production in marine ecosystems. However, our understanding of the specific effects of UVR on the primary production of natural phytoplankton communities is still limited. We utilized the 13C stable isotope to quantify prima...

In the Philippine Sea, mesoscale eddies have been frequently observed, but little is known about their contributions to the biological productivity and community structure of phytoplankton in the region. In situ carbon and nitrogen uptake rates and phytoplankton community structure were investigated in the Philippine Sea based on the ¹³C‐¹⁵N dual‐t...
