Antarctic sea ice is a key element in the global climate system. Its growth each winter creates cold, deep ocean conditions that help sustain Antarctica’s ice sheets, it modifies storms in the Southern Hemisphere, and it affects the rate of global warming.
The images featured in this series of Ross Dependency stamps represent the work of New Zealand’s leading Antarctic sea ice scientists who are conducting ground-breaking research in McMurdo Sound, investigating how the changing climate may impact the fragile sea ice balance in Antarctica.
This issue includes four stamps, a stamp first day cover, a miniature sheet, a miniature sheet first day cover, a presentation pack and a Limited Edition, and the stamps issue on 2 November.
