In order to clarify the primary productivity in coastal area, we have sampled sea water in the surf zone on Kashima-Nada since July 1999, and investigated the variations of nutrients and chl.a. It has been shown that the temporal variations of nutrients concentration are due to various meteorological or oceanographic conditions, and vertical mixture or stratification of sea water as seasonal change. It is thought that the difference in the rainfall from late spring to summer cause the yearly variation of nutrients concentration and phytoplankton biomass in summer. Moreover, it is thought that course of the Kuroshio Current in winter effects nutrients concentration and phytoplankton biomass in period of spring bloom.
