Globally, heat flow measurements are sparse – but this is particularly true of the Arctic Ocean. In a new article, CEED's Grace Shephard and co-workers present new heat flow measurements from 15 distinct sites in the Central Arctic Ocean, and compare the results in the context of existing measurements. They have new measurements from the Amerasia Basin (Marvin Spur, Alpha Ridge), the Lomonosov Ridge (crest and foot) and Eurasia Basin (Yermak Plateau and Amundsen Basin). The possibility of a “North Pole thermal anomaly” sounds pretty interesting — the researchers explore surface and deeper mantle evidence, or the lack thereof, for such a feature and its relation to the heat flow measurements.
