A Scenario of the Late‐Pleistocene‐Holocene Changes in the Distributional Range of Antarctic Krill ( Euphausia superba)
Abstract. Oceanographic evidence along with the data on Euphausia superba distribution indicate that the reproductive range of this species is related to the southernmost core of the Antarctic Circumpolar Current (ACC), the Weddell Gyre, the Ross Gyre, and the systems of mesoscale eddies in the Bell...
