Abstract:

在粤东上升流区和南海北部陆架陆坡区共选取7条断面,通过分析水体的温度、盐度、密度、浊度、叶绿素浓度特征和悬浮体现场粒度平均粒径、体积浓度特征等,初步研究了南海北部海洋雾状层的特征及其受控机制。研究发现粤东上升流区底部雾状层普遍发育,在个别站位存在表层雾状层,高能的近岸浪流作用和来自港湾、河流的泥沙为表层雾状层和底部雾状层提供物源;南海北部陆架陆坡区底部雾状层也普遍发育,在珠江口外的内陆架和外陆架陆坡区表层雾状层比较常见,陆坡区中层雾状层比较发育,本区雾状层的物源主要来自珠江和台湾岛西南部河流的入海泥沙、海底沉积物以及生源颗粒物。南海北部底部雾状层的强度和扩散范围主要受水动力条件、河流入海物质的扩散和底质再悬浮等控制。
