摘要

Abstract

Based on the field data obtained during cruises on the shelf of the East China Sea from 1997 to 1999

seasonal variations of coastal upwelling on the inner shelf are discussed by using cross-shelf transect profiles and horizontal distributions of chemical and hydrographic variables. Results show that the coastal upwelling was year-round

but the areas and intensities of the upwelling were quite different in season. The coastal upwelling occurred in all of the coastal areas of the region in spring and summer

but in autumn only in the area off Zhejiang Province

and in winter in the area off Fujian Province. It was the strongest in summer and the weakest in winter. Geographically

it was the strongest in the area off Zhejiang Province and the weakest in the southmost or northmost parts of the East China Sea. The estimated nutrient fluxes upward into euphotic zone through coastal upwelling were quite large

especially for phosphate

which contributed significantly to primary production and improved the nutrient structure of the coastal ecosystem in the East China Sea.
