A Southern Ocean archipelago enhances feeding opportunities for a krill predator

Productivity in the oceans is heightened around oceanographic and bathymetric features such as fronts and islands. This can have a flow‐on effect, providing increased food availability for higher trophic level species. Using data from a 5‐day combined visual and acoustic survey, we examined the hypothesis that higher Antarctic krill ( Euphausia superba ) density provides a lucrative resource for humpback whales ( Megaptera novaeangliae ) at a...
