The calls come at a first-ever international conference on a way of observing the area in Hobart
The sea ice in the Southern Ocean around Antarctica is often described as the beating heart of the earth - it normally forms during winter and melts during summer.
Dr Andrew Meijers is the Deputy Science Leader at the Polar Oceans Program at the British Antarctic Survey. This uncertainty has prompted a group of 300 scientists from 25 countries to call for a sustained and coordinated Southern Ocean Observing system. "It's a race between the science and whatever the changes that are occurring that the science is seeking to measure. So we need urgent action in science but also in communication of science to policy, to get the decision-makers to understand what's happening, what may happen in the future and how we can best manage those changes"
Dr Meijers says that one way to improve the data would be to expand a cost-effective robotic monitoring program that is already being used extensively across the globe.
