The world's largest marine reserve has been created off Antarctica – with more than 1.5m sq km of the Ross Sea now protected.

The deal brokered last Friday, between 24 countries and the European Union, means that this remote and largely pristine stretch of ocean will now be set aside as a no-take ‘general protection zone’. 

The Ross Sea is largely untouched by humans, its nutrient-rich waters the most productive in the Antarctic, leading to huge plankton and krill blooms supporting vast numbers of fish, seals, penguins, and whales.

This landmark protection agreement, prohibiting fishing in the Ross Sea, came at the conclusion of two weeks of discussions in Hobart, at the annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) with the new protective measures to go into force on December 1, 2017.
