From the Caltin Arctic Survey website: Four polar explorers are conducting an extreme expedition, travelling up to 350 miles (560 km) across floating sea ice from early March to May during the harsh winter to spring transition. Their mission – only possible because of their unique experience – is to gather valuable oceanographic and ice data for Dr Boxall and the National Oceanography Centre in Southampton, UK.
