基于Bio-Argo浮标数据研究孟加拉湾中部海域溶解氧分布
The distribution of dissolved oxygen in the central Bay of Bengal based on Bio-Argo observation
摘要
Abstract
The distribution of dissolved oxygen(DO)affects the survival of marine organisms.In order to explore the temporal and spatial variation of sea surface DO and oxycline in the Oxygen Minimum Zone(OMZ)of Bay of Bengal(BoB),we investigated the vertical DO distribution from 0 to 200 m in the central BoB using Bio-Argo and remote sensing data from 2013 to 2017.The results showed that the salinity stratification caused by the input of a large amount of runoff and rainfall induced the significant change of the DO in the central BoB,and DO decreased significantly at～40 m,and dropped to less than 20 μmol·kg-1 within 200 m.The sea surface DO was negatively correlated with the sea surface temperature(r=-0.75).The oxycline depth was significantly correlated with the 23℃isotherm and sea level anomaly(r=0.93 and 0.81).The surface DO concentration was mainly affected by the surface temperature,and the oxycline depth was mainly controlled by the mesoscale eddies in the OMZ of the BoB.关键词
