人们过去曾猜测,冰山从阿拉斯加和加拿大山脉向西延伸到大陆架的最边缘,也就是大陆架扁平的、延伸到海洋中的水下大陆那部分。
It had been assumed that the ice extended westward from the Alaskan/Canadian mountains to the very edge of the continental shelf, the flat, submerged part of the continent that extends into the ocean.
在这个地方的大陆架是大约600米深,当从外面来的暖流碰上大陆架,就会沿大陆架向上升到浮着的冰川下面。
The continental shelf here is about 600 meters (2, 000 feet) deep, and as the warm water from the open ocean meets the shelf, it continues to flow toward land and rises beneath the floating glacier.
