摘      要：We compare the characteristics of Circumpolar Deep Water(CDW)in the Amundsen Sea based on Conductivity-Temperature-Depth(CTD)records in the World Ocean Database.There are considerable numbers of ship-based CTD casts in the year 1994,2000,2007 and 2009.After confining temporal-and spatial-windows,several stations are emerged as having at-least two casts in different years.The comparisons show that the CDWs turn warmer and salter on shelf and near ice shelf.The results therefore describe the geographic differences of CDW changes,and exhibit rareness of ship-based CTD survey in the Amundsen Sea.
