Abstract

Abstract

In recent years,the area of sea ice have been substantially reduced in the Arctic Ocean. The reason behind this is still in debate. Based on the data of hydrology and remote sensing satellite from 2003 to 2011,the relationship of Pacific Water and sea ice in the Canada Basin were studied. Spatial distributions of potential temperature of Pacific Water and sea ice concentration in 2006 were compared with those in 2007. It was found that the warm Pacific Water anomalies entered the central Canada Basin in January to March 2007,which probably led to the melting of sea ice in the summer of 2007. Between 2003 and 2011,it was found that the potential temperature of Pacific Water and sea ice concentration were negatively correlated in the central Canada Basin. In August 2007,the spatial correlation was also found to be negative in the central Canada Basin. It might indicate that the inflow of warm Pacific Water anomalies transferred the heat upwardly. To a certain extent, the heat melted the sea ice and triggered the ice-albedo feedback,which resulted in the decline of sea ice area. Therefore,Pacific Summer Water,which travels through the Bering Strait into the Arctic Ocean,plays an important role in the reduction of sea ice area in the Arctic Ocean.
