Wind-blown Antarctic sea ice helps drive ocean circulation
27 June, 2016
Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study published today in the journal Nature Geoscience (Monday 27 June) shows how that ice migration may be more important for the global ocean circulation than anyone realized.
