Marine ecosystem responses to global climate change in the Bering and Chukchi Seas

2007年和2008年的实地调查和卫星遥感数据显示：1。与往年相比，2007年小型浮游植物占主导地位。2.预计鲑鱼的分布区域将显著减少，鲑鱼将不得不向北移动，如北冰洋，那里的海洋将缩小。3.没有认识到随着海冰范围的迅速减少，底层鱼类的种类发生了重大变化。

In situ investigations in 2007 and 2008 and satellite remote sensing data revealed the following : 1. Smaller phytoplankton was dominant in 2007 compared with past years. 2. Remarkable decrease in distribution area of chum salmon is anticipated and the salmon will have to move toward north such as the Arctic Ocean where sea will be shrunk. 3. Significant change in species of demersal fishes with rapid decline of sea ice extent was not recognized.
