Quick Summary

The Eurasia Basin is a major deep basin within the Arctic Ocean. It was formed by seafloor spreading along the Nansen-Gakkel Ridge. This basin is located on the European side of the Lomonosov Ridge, which divides the Arctic Ocean into two main basins: the Eurasia Basin and the Amerasia Basin. The Eurasia Basin is further divided by the Nansen Cordillera into the Fram Basin and the Nansen Basin. The sediments on the Arctic Ocean floor, including those in the Eurasia Basin, record past environmental conditions, climate, and ecosystems.1
