Plankton community structure and dynamics versus physical structure from Terra Nova Bay to Ross Ice Shelf (Antarctica).
During the austral summer 1997/1998, an oceanographic cruise was carried out on a large-scale grid in the Ross Sea. In this contribution, we focused our attention on the coastal area from the Terra Nova Bay (TBN) polynya to the eastern edge of the Ross Ice Shelf (RIS). We analyzed picoplankton, nano...
