Emperor penguins breed through the dark Antarctic winter on sea ice, in one of Earth’s most extreme environments, making them difficult to monitor yet invaluable as indicators of Southern Ocean health. Our program follows penguins across their lives and vast ocean areas by combining long-term field observations with electronic tagging, ...
Deep-ocean predators depend on patchy prey resources embedded within a poorly understood physical environment, making it difficult to determine how oceanographic variability structures prey fields and shapes predator behavior at bathypelagic depths. Using goose-beaked whales in the Southern California Bight as a case study, I will synthesize recent work combining ...
