Eight-month expedition to study the impact of climate change

As Christopher Nolan's The Odyssey, an adaptation of Homer's epic poem, arrives in cinemas, a very different odyssey is about to begin. Next month, a team of scientists will travel to the remote Arctic town of Kirkenes in Norway to board the floating laboratory Tara Polar Station for an eight-month expedition. The mission will study the impact of climate change and pollution on the Arctic Ocean. For more, we're joined by Marcel Babin, Scientific Director of the Tara Polaris I expedition.
