Ziphius cavirostris presence relative to the vertical and temporal variability of oceanographic conditions in the Southern California Bight
Abstract The oceanographic conditions of the Southern California Bight (SCB) dictate the distribution and abundance of prey resources and therefore the presence of mobile predators, such as goose‐beaked whales (Ziphius cavirostris). Goose‐beaked whales are deep‐diving odontocetes that spend a majori...
