Antarctic Seafloor Mission makes ‘Astounding’ Discoveries

A team of international researchers on board New Zealand’s Ross Sea ‘ACTUATE’ Voyage 2025 is celebrating the discovery of vibrant, complex seafloor communities near the Ross ice shelf and Ross Island.

The benthic ecology team on board NIWA’s RV Tangaroa includes University of Tasmania marine ecologist and ACEAS Chief Investigator, Dr Nicole Hill, who describes the area as “pretty much as far south as you can get by sea and mind-boggling in scale.”

This 39-day voyage, including 30 days within the Antarctic Treaty area, is the Tangaroa’s 16th voyage to Antarctica and the Southern Ocean. It departed from Wellington NZ, in mid-January and arrived at Ross Island at month’s end.

The Ross Sea is the southern-most sea in the world and home to the planet’s third-largest Marine Protected Area.
