Taking the pulse of the Ross Sea Outflow
Melt water produced by ice shelves around Antarctica influences ocean currents, temperature and salinity around the Southern Ocean and globally. The Ross Ice Shelf to the south of New Zealand is amongst the largest Antarctic ice shelves. Currently, our capacity to model its outflow and impact on our climate system is limited.
- Project Duration: July 2017 - July 2019
- Project budget: $300,000 (GST excl.)
This project will take new measurements, both from ships and from robotic gliders programmed to fly up and down through the ocean, to understand how water moves between the shallow shelf and the deeper ocean. We’ll compare our findings to historical data and document the ways in which the Ross Sea outflow has changed over the past decade.
In doing so, we’ll improve how these processes are simulated in the NZ Earth System Model and contribute to more accurate predictions of New Zealand’s future climate.

Latest news and updates
The recent Edgecumbe floods saw raw sewage floating through the streets, making the clean-up extremely challenging. Over 300 homes in the district were damaged and six months later, 240 houses are still unliveable. Flood-proofing the town itself remains a distant goal.
The Deep South Challenge announces new research into who should bear the cost of our changing climate, and when.
All over New Zealand, from Haumoana to Westport, from Edgecumbe to the Kāpiti Coast, from Dunedin to Wellington City, homeowners and businesses are starting to feel the financial effects of climate change.
Susan Livengood is the Partnerships Director of the Deep South Challenge, and works within the Engagement programme – which tries to connect what’s happening in every programme of the challenge with both the broader public and with targeted individuals and organisations throughout New Zealand’s public and private sectors.
