| 摘 要： | Hydrological character and Sea-current profiles structure are studied andanalyzed in sea-area of the front of Amery Ice Shelf,Prydz Bay with LADCP,CTDdata.These LADCP,CTD data were acquired during the 19th Chinese Antarctic Sci-entific Expedition.Results of this study agree with that,there exist four differentkinds of water masses in the area of the front of Amery Ice Shelf in the summer of Ant-arctica.Current distribution presents a semi-circumfluence which flows in at the eastand flows out in the west.Moreover,clockwise and anti-clockwise vortices werefound in upper layer and mid-layer in the Prydz Bay.Western areas of these anti-clockwise vortices are positions of inflows from Prydz Bay to Amery Ice Shelf.Thesource of these inflows is the coastal westward current originated in the east of PrydzBay.All these characteristics come down to the pattern of circumfluence,ice meltrate under Ice Shelf,scale of Ice Shelf water production and form of water exchangesbetween area of Ice Shelf and area of Prydz Bay.

| Abstract: | Hydrological character and Sea-current profiles structure are studied and analyzed in sea-area of the front of Amery Ice Shelf, Prydz Bay with LADCP, CTD data. These LADCP, CTD data were acquired during the 19th Chinese Antarctic Scientific Expedition. Results of this study agree with that, there exist four different kinds of water masses in the area of the front of Amery Ice Shelf in the summer of Antarctica. Current distribution presents a semi-circumfluence which flows in at the east and flows out in the west. Moreover, clockwise and anti - clockwise vortices were found in upper layer and mid-layer in the Prydz Bay. Western areas of these anticlockwise vortices are positions of inflows from Prydz Bay to Amery Ice Shelf. The source of these inflows is the coastal westward current originated in the east of Prydz Bay. All these characteristics come down to the pattern of circumfluence, ice melt rate under Ice Shelf, scale of Ice Shelf water production and form of water exchanges between area of Ice Shelf and area of Prydz Bay. |
