In September 2006 the scientific polar schooner Tara sailed into the pack-ice and has been allowed to drift with the ocean currents and wind.
The two-masted manned vessel (ex Seamaster of New Zealand sailing hero Sir Peter Blake fame) is crammed full of sensors to monitor the ocean, atmosphere and ice.
The aluminium hulled, ice-strengthened boat is now on its way to the island of Spitsbergen in the Arctic Ocean.
