In the interests of brevity, we include most of the major oceanographic expeditions of the ice-covered central basins, but many other important expeditions are excluded, such as land-based ethnological, biological, and geological studies. In particular, modern scientific investigations of the Sea of Okhotsk, Bering Sea, Hudson Bay, Labrador Sea, and Greenland-Iceland-Norwegian Seas are not included. A considerable amount of effort has been made to ensure that information presented in this history is objective and accurate, but the compilers of this document are not historians, so readers are referred to the references for more thorough descriptions.
