The six-week Australia-New Zealand Antarctic Ecosystem Voyage saw RV Tangaroa travel through the Southern Ocean to the Ross Sea to conduct a range of scientific fieldwork. The voyage was a collaboration between Antarctica New Zealand, the New Zealand National Institute of Water and Atmospheric Research (NIWA) and the Australian Antarctic Division.
Research focused on the feeding areas of cetaceans, primarily blue whales and humpback whales, to better understand factors affecting their numbers and distribution. Work was also undertaken in the Ross Sea Slope area to explore any ecosystem effects of commercial toothfish fishing.
