Summer phytoplankton distributions in the Weddell Sea
The quantitative composition of phytoplankton was studied along a transect of 14 hydrographic stations, between the southern coast of the Weddell Sea and the Antarctic Peninsula, during the austral summer of 1984-1985. The most apparent feature of the phytoplankton distribution was the presence of a...
