R.: Oceanography of the Canadian Shelf of the Beaufort Sea: A Setting for Marine Life
ABSTRACT. Conservation of marine biodiversity in the Beaufort Sea demands that we understand what individual organisms require of their physical and geochemical environments in order to survive. Specifically, how do the extraordinary spatial and seasonal variations in ice cover, temperature, light,...
