A transient iceberg kingdom meanders through the Southern Ocean

January 29, 2020

This image of icebergs at Rothera Station in Antarctica was taken during the final cruise of of the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES) project aboard the British icebreaker RRS James Clark Ross. This five-year joint US/UK  field program was aimed at studying mixing in the Southern Ocean–a critical regulator of Earth’s climate processes–and examining connections between the circumpolar current and the three large ocean basins (Atlantic, Pacific, and Indian) immediately to the north.
