Abstract
Ulleung basin (UB) located in southwestern part of East Sea (Japan Sea) is considered having a high primary productivity even in summer. There are several studies suggest nutrient supplements maintaining high primary productivity in the UB such as wind-driven upwelling, current transport, eddy-induced upwelling. This study focused on impact of nutrient supplements by vertical mixing in the UB applying the one dimensional biological model (1D GOTM-ERSEM). We used bi-monthly observed temperature and salinity data to assilmilate simulated temperature and salinity. We found vertical mixing mainly contributes to primary productivity and other processes relatively low and accurate physical structure roles importantly. Also we found vertical distribution of temperature and salinity may control the blooming time of phytoplankton. The diatom which is usually dominant was limited due to lack of silicate which mean not only silicate supplement vertically but also horizontally is important in the area.such as wind-driven upwelling, current transport, eddy-induced upwelling.
