| Abstract: | Based on the Australian data in Nov.1982 and in Feb.1987,as well as the data by the Chinese "Ji Di" Research vessel,we have reached the following conclusIOns:The hydrologic characteristics of Prydz Bay in the early suaver are:1.Thehydrologic characteristics of Prydz Bay are effected by the longshore ice shelf.Outside Davis Station,the water of low temperature, low salinity and low-density iscaused by the melted water of the West Ice Shelf. It extends north-westward until75"E and 68"40'S,150km away from the coast.At greater depths the tongue deflects westward with increasing depth.Near the Fram Bank the water has also low temperature and low salinity,which is related to the malted water of the Amery IceShelf and flows along the east margin of the Fram Bank;2.The center water,withlow temperature and low salinity in the east to the Amery Ice Shelf is caused by thesinking of the surface water; 3.The center water with high salinity and high density northwest to the Bay is caused by the upwelling of bottom water; 4.The opensea water invades only the margin part of the continental shelf.The hydrologic characteristics of Prydz Bay in late summer are:1.During thelate summer,the density of the three low temperature and low salinity tongues remarkably weakens and can not control the hydrologic regime as it does in the earlysummer; 2.At the northwest cutting place of the continental shelf, the southwardinvading of the Summer Surface Water and the Winter Residual Water is strongerthan in the early summer;3.The upwelling area lies in the middle of the Bay,whose center deflects to the Amery Ice Shelf within the 50m layer and deflects.notrhward to the Bay;in the 100-400m layer it is mainly in E-W direction.Theintensity and scope of the upwelling increases greatly in the center of the Bay. |
