Spring phytoplankton onset after the ice break-up and sea-ice signature (Adélie Land, East Antarctica)
The phytoplankton onset following the spring ice break-up in Adélie Land, East Antarctica, was studied along a short transect, from 400 m off the continent to 5 km offshore, during the austral summer of 2002. Eight days after the ice break-up, some large colonial and...
