The Second Kamchatka Expedition (1733-43) was a very large scientific expedition. It was also led by Bering. The scientific expedition sent out smaller explorations to chart the coasts of Siberia, the Pacific, and several research expeditions. Ships were sent to Japan and America to promote Russian interests. Bering reached Alaska in 1741. On the return journey they had to stop at Bering Island. While there nearly half the crew, including Bering, died. In 1991, Danish archaeologists found his grave.
