A special issue of the Philosophical Transactions of the Royal Society A has been published today (Monday 2 June) which brings together a collection of papers on many of the unresolved issues relating to the Southern Ocean. Professor Michael Meredith from the British Antarctic Survey was a guest editor on the issue; ‘The Southern Ocean: new insights into circulation, carbon and climate’.

The research includes: Why greenhouse gases and the ozone holes are melting the Arctic sea ice but are having a cooling effect in some parts of Antarctica, and how dust, which provides iron and essential nutrients to the ocean, might have been the cause of increased biological productivity in the southern Atlantic Ocean during the last ice age.
