Yesterday we passed through the Aleutian Islands. The Aleutian Islands are a chain of volcanic islands dividing the Bering Sea from the Pacific Ocean. We were lucky: the visibility was good, and it was still light outside, so that we could see one of the islands relatively clearly, and two others could be seen (using binoculars) on the horizon. South of the islands is the Aleutian trench, where the Pacific Ocean is nearly 8000 meters deep.
The Bering Sea is a marginal sea of the Pacific Ocean, just as the North Sea is a marginal sea of the Atlantic Ocean. But the Bering Sea covers four times as much area as the North Sea and is also much deeper. For our last two stations, we will deploy our instruments once more to depths of 3500 meters, in order to collect sediments and water.
