Abstract
Ulleung basin (UB) located in southwestern part of East Sea (Japan Sea) is considered having a high primary productivity due to nutrient supplements such as wind-driven upwelling, current transport, eddy-induced upwelling. We applied a vertically one-dimensional biological model (1D GOTM-ERSEM) to Ulleung basin focusing on timing and magnitude of phytoplankton bloom. To investigate impact of stratification on timing and intensity of phytoplankton bloom in the Ulleung basin, three different temperature and salinity dataset were assimilated in GOTM. When MLD in winter is relatively shallow, spring bloom tends to occur earlier (in Feb.) by two months, compare with observations. The magnitude is smaller than the observations. In contrast when MLD in winter is relatively deep, timing of spring bloom and intensity become more realistic. This represents the stratification contributes to determining timing of spring bloom and magnitude of spring bloom in the Ulleung Basin.ically one-dimensional biological model (1D GOTM-ERSEM) to Ulleung basin focusing on timing and magnitude of phytoplankton bloom.
