ESA Envisat Images: Improve safety in icy Southern Ocean

An award-winning new website is using realtime imagery from ESA's Envisat satellite to provide a wealth of information on sea ice to aid safe passage through the treacherous waters of the Antarctic.

Although remote, the Southern Ocean is an increasingly busy route for sea traffic.

These seas are used more and more to conduct scientific research, transport freight, harvest fertile fishing grounds and carry tourists to experience one of Earth's last wildernesses.

However, ever-changing pack ice and icebergs pose a serious danger to marine safety – as demonstrated by the loss of the MS Explorer tourist ship in 2007

Owing to the remote and inhospitable nature of the Southern Ocean, satellite imagery offers the only real practical means of obtaining timely information on sea ice required for the safe passage of marine traffic. While safety may be a primary concern, so is cost, as sea ice can significantly delay passage times.

For some years, ESA has been providing these key data to aid navigation – but the 'Polar View' ice-monitoring service in the Antarctic has recently been greatly improved by a wealth of satellite images made accessible through a new interactive website.
