Trophic interactions within the Ross Sea continental shelf ecosystem.
The continental shelf of the Ross Sea is one of the Antarctic’s most intensively studied regions. We review the available data on the region’s physical characteristics (currents and ice concentrations) and their spatial variations, as well as components of the neritic food web, including lower and m...
