2018-2019 USAP Field Season
EAGER: Acoustic ecology of foraging Antarctic blue whales in the vicinity of Antarctic krill
Dr. Ana NMI Sirovic
Supporting Stations: Special Project
The Australian Antarctic Division and the University of Tasmania will lead an international voyage to the Antarctic in the austral summer of 2019. The goal of this project is to advance the understanding of blue whale behavior and krill dynamics through acoustic mapping. US participants will deploy passive and active acoustic technologies on a fixed mooring to track and localize blue whales. The acoustic information will allow better directing of ship operations towards aggregations of animals such that fine-scale acoustic tracking and prey-field mapping can be achieved.
Field Season Overview
Two USAP participants will deploy on the Australian research vessel, R/V Investigator, from mid January to early March in collaboration with the Australian Antarctic Division. The study area is south of 60° S and between 140° E and 175° W. USAP participants will contribute their acoustic expertise to the cruise, which will use autonomous underwater vehicles, short-term tags, photogrammetry and ship-based, real-time, active and passive acoustics.
