黄海南部的溶解无机氮
Dissolved Inorganic Nitrogen in the Southern Yellow Sea
摘要
Abstract
Based on the investigation data from the project “Res earch onthe Dynamic of Seawater Circulation and Mass Long-Term Transportation ”, which was implemented in May 1998, the distribution patterns of dissolved in organic nitrogen (DIN) in the Southern Yellow Sea in May were discussed. The major results could be summarized as (1) The horizontal distribution features of am monia and nitrite show high concentrations in the coastal area and relatively low concentrations in the central area. In the light of the distribution of nitrate, high concentration was identified in the area off the Changjiang River estuary. In the central and northern part of the Southern Yellow Sea, the depth is great and the concentration of nitrate is low. The input of the Changjiang River fr esh water with high concentration nutrients and the alongshore currents should be responsible for the distribution pattern. (2) In the deep-water area, the vertical profiles of DIN stratified obviously. The isopleth of DIN has a significant trend of going up, which is caused by the upwelling Yellow Sea Cold Water. The concentration of nitrate increases from surface to bottom, with a sudden increa se at the 10m layer. (3) The content of chl-a at the surface is high in the alongshore area, but low in the central area.关键词
