- Coastal upwelling (CU) is an important process that causes changes in physical and chemical properties, resulting
in variation of biological processes in a coastal area. In the southwestern part of the East/Japan Sea
(SWES), CU has been alleged as one of the mechanisms responsible for higher net primary production (NPP) than
the rest of the East/Japan Sea. We provide, for the first time, high spatial resolution underway observations of
sea surface temperature, salinity, chlorophyll-a fluorescence and Δ(O2/Ar), revealing the physical and biological
characteristics of the upwelled waters in the SWES. The cold, upwelled waters retained high fluorescence and
Δ(O2/Ar), consistent with enhanced phytoplankton biomass and biological O2 production by CU. The net
community production (NCP) in the ambient and upwelled waters were 33 ± 19 and
77 ± 41 mmol O2m？2 d？1, respectively. The latter should be considered as a lower bound, containing a significant
fraction of low O2 waters from subsurface. Satellite observation indicated that NPP in the upwelled
waters were higher than the ambient waters by 51%. This implies that up to half of higher NPP in the SWES than
the rest of the East/Japan Sea can be ascribed to CU events.
