Melting Ice in the NZESM
Freshwater from icebergs and ice shelf melt in the NZESM
While the reduction of Arctic sea ice is alarming researchers worldwide, Antarctic sea ice extent has actually been increasing over the past 30 years.
- Project budget: $300,000
- Project duration: July 2017 – June 2019
Changes in Antarctic sea ice can have a huge effect on weather patterns over New Zealand, causing varying wind patterns that lead to cyclones, increased rainfall and abnormal temperatures. In addition, the amount of Antarctic sea ice affects the global climate, by influencing the heat uptake of the Southern Ocean – one of the world’s largest carbon sinks.
Current climate models have been unable to replicate the increase in Antarctic sea ice. Through model development and improvements, this project will investigate if the recent increase in Antarctic sea ice is being influenced by freshwater from melting icebergs or from the bases of Antarctic ice shelves.
Our research will inform the development of the NZ Earth System Model.

Latest news and updates
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.
