EAGER: Collaborative Research: Acoustic Ecology of Foraging Antarctic Blue Whales in the Vicinity of Antarctic Krill
Short Title:
Acoustic ecology of Antarctic blue whales
Start Date:
End Date:
In austral summer 2019, a 48 day, multi-country, interdisciplinary research voyage mapped Antarctic krill (Euphausia superba) and baleen whale, blue whale (Balaenoptera musculus) and fin whale (B. physalus) distributions in particular off East Antarctica. We detected, tracked and localized blue whales and mapped prey fields in the vicinity of a fixed acoustic mooring that combined passive and active acoustics for collection of concurrent predator and prey data. By coupling moored data collection with the ship-based survey focusing on Antarctic blue whale behaviour and krill dynamics, we investigated the dynamics of blue whales and their prey. We found that the production of social calls, D calls of blue whales and 40 Hz calls of fin whales, was correlated with the krill biomass over a week-long period.
