Shelfbreak Upwelling in the Western Beaufort Sea, Zooplankton Morphometrics data for August 2018
Atmospherically-forced wind-induced upwelling along the shelf break leads to enhanced feeding opportunities for intermediate links in the pelagic ecosystem that in turn sustain the exploitation of this environment by animals such as beluga, seabirds, and seals. The Beaufort Sea shelf break is a hots...
