L'Astrolabe enters the ice with penguins in front

Platform for the 15 years of continuous Southern Ocean measurements, L'Astrolabe, enters the ice in January en route to the French Antarctic base, Dumont D'Urville.

The wind, climate change and the Southern oceans

We all know that the oceans are warming, especially in our polar regions. But what role does wind play in raising surface, or deeper, ocean temperatures? A 15 year study of water temperature profiles undertaken by CSIRO, French and US scientists is revealing some surprising answers. (5:46)

This is a very long term collaboration between the French Polar Institute, the CSIRO’s Wealth from Oceans Flagship, and scientists from the Scripps Institution of Oceanography.

In this podcast, Dr Rosemary Morrow from the French Polar Institute explains how the French supply ship, L’Astrolabe, its crew and volunteers have played an important part in revealing the shifts in temperature and salinity in the very cold waters between Hobart and the French Antarctic base of Dumont Durville.

Called SURVOSTRAL (Surveillance of the Ocean Austral), the program has provided researchers with thousands of individual readings.
