“…Although the surface water of the East Sea is connected with the North Pacific Ocean through the shallow straits (<200 m) (the Korea‐Tsushima Strait, the Soya Strait, the Tatarsky Strait, and the Tsugaru Strait), deep water is almost completely isolated. The dissolved oxygen concentration in deep water of the East Sea (230–250 µmol/L) is significantly higher than the North Pacific (40–70 µmol/L) due to rapid water ventilation [ Kim et al ., ]. The oxygen minimum zone in the deep East Sea extends from 1500 m to 2500 m.…”

The distribution of fluorescent dissolved organic matter (FDOM) in the East Sea (Sea of Japan) was examined by excitation‐emission matrix spectroscopy with parallel factor analysis (PARAFAC). Humic‐like FDOM (FDOMH) increased with depth and was significantly correlated with Apparent Oxygen Utilization (AOU), indicating that FDOMH in the deep water is mainly produced by oxidation of organic matter. In addition, a surprisingly large excess of FDOMH relative to that expected from the observed AOU was found from 1000 m to the bottom (up to 3500 m). Based on the high‐resolution geographical distribution and characteristics of FDOM in the East Sea, we conclude that this excess likely originates from anaerobic FDOMH production in subsurface bottom sediments. This FDOMH flux accounts for 8–15% of the total FDOM production in the water column. Our results suggest that anaerobic activities in subsurface sediments are an important hidden source of FDOM in the ocean.

“…The northern part of East Sea is characterized by cold water, originating from North Korea Cold Current (NKCC), a branch of Liman Current (Cough et al, 2000;Talleyet al, 2006). The southern part of sea is characterized by warm water, influenced by East Korea Warm Current (EKWC), a branch of Tsushima Warm Current (Chang et al, 2002;Ashjian et al, 2005;Kim et al, 2016). Dokdo is centrally located in the southern East Sea/Japan Sea.…”

The aim of this study was to investigate the seasonal changes in distribution, composition and abundance of zooplankton community in relation with hydrography such as temperature and salinity in the East Sea. Seasonal changes of zooplankton community were studied at 12 stations near Dokdo in the East Sea. Zooplankton were seasonally sampled in 2011. Water temperature and salinity were simultaneously measured at the zooplankton sampling sites. The mean surface water temperature was highest in summer, lowest in winter and intermediate in spring and fall. The mean surface water salinity was highest in winter and spring, lowest in summer and intermediate in fall. Total 215 species belonging to 65 families were identified. Zooplankton mean densities gradually increased from winter to fall. Total species number was lowest in winter and highest in summer. Copepods prevailed as dominant zooplankton groups in all seasons. The mean densities of dominant zooplankton species varied with seasons. Zooplankton communities varied with season, particularly water masses were driven by water currents as a main factor controlling zooplankton community composition, abundance and distribution.
