Greenland's Pristine Seas: Freezing A Moment In Time - Enric Sala

Last week, the British government announced their intention to establish the world's largest marine reserve around the Pitcairn Island's pristine seas. National Geographic Explorer in Residence Enric Sala's Pristine Seas team helped the UK's decision makers understand just how perfect the ocean life around the islands are. And now, Sala and his team have turned their focus to colder waters off Greenland's coast to establish an environmental baseline for what will be the last region in which the water will remain frozen throughout the year.
