Ross Sea Voyage 2024

The Antarctic Science Platform is collaborating with the Italian Antarctic Research Programme on a voyage to the Ross Sea in Antarctica. In January 2024, twelve members of the New Zealand team will join Italian colleagues on the RV Laura Bassi for a two-month voyage of discovery.

Voyage track

Our team will spend two months at sea, witnessing sea-ice retreat firsthand.

The planned voyage track is anti-clockwise around the Ross Sea.

The RV Laura Bassi departed from the Port of Lyttelton, New Zealand, on 6 January. It entered the Ross Sea at the western side a week later, working along the Victoria Land Coast and in Terra Nova Bay.

The ship called in at the Italian Antarctic research station, Mario Zuchelli, to collect scientists who had flown in from McMurdo Station/Scott Base.

The vessel is then transiting along the front of the Ross Ice Shelf, then north and west along the continental shelf break.

Our team aims to arrive in Lyttelton on about 3 March.

Voyage Science

The New Zealand science plan has three key objectives.


Ross Sea Polynya

Polynya are sea ice production factories. They are (i) difficult places to make measurements and (ii) poorly represented in climate models – and knowledge of them is critical at a time of rapidly declining sea ice. Our goal for the voyage is to deploy state of the art sensors designed to operate and gather information over a range of spatial and temporal scales, to develop new knowledge of Antarctica’s most productive polynya – the Ross Sea Polynya.

Ross Sea region Marine Protected Area (MPA)

We will use a range of current research tools, including isotopic analysis, gene-scaping, eDNA, acoustics, gathering of key environmental measurements, and deployment of ROVs and ocean gliders, to study Ross Sea pelagic and benthic (coastal) ecosystems. This data will be used, along with existing and future research, to establish a baseline of the Ross Sea region MPA ecosystem function and coastal biodiversity to determine how vulnerable this ecosystem is to the future changes anticipated for this region.

Seabed coring

An important aspect of Platform research is to use sediment records to better understand how the Ross Sea responded to historic climatic conditions. Knowing how sea ice was distributed, and how that impacted on primary production at times when the climate was naturally warmer can inform predictions of how things will respond when such conditions return. To support this research, we aim to collect and analyse shallow cores along the front of the Ross Ice Shelf, areas that we have seldom visited, to enhance existing transfer functions.

Growing Antarctic careers

We are creating inter-generational knowledge in real time.

The New Zealand-Italy research voyage provides an opportunity for Early Career Researchers (ECR) and postgraduate students. The New Zealand contingent includes five ECRs and four PhD students.

MAC3 Impact Philanthropies have provided funding to facilitate New Zealand and Italian ECRs with a passion for Antarctica to use the 2024 Ross Sea Voyage to grow their Antarctic research careers. The recipients will put this support, after the voyage is completed, towards expenses for research time, for undertaking additional lab analyses, producing high quality publications, media engagement and conference travel.

The joint voyage provides an exciting opportunity to build a cohort of Antarctic ECRs.
