The world's biggest marine reserve in Antarctica officially comes into effect on Friday, in what has been hailed as a watershed moment in conservation. The marine protected area in the Ross Sea curbs damaging activities such as fishing, to protect wildlife including Adelie and emperor penguins in the high seas off Antarctica.

The failure of a fuel pump and engine left the Silver Cloud adrift as it headed toward Antarctica on November 20, 2017. Power was reportedly restored to the ship in about an hour, permitting the cruise vessel to return to Puerto Madryn in the South Atlantic for repairs.

The Antarctic is being melted from below, according to a new study by Nasa - and a type of buried super-volcano may be to blame. The Nasa study adds evidence that there is powerful geothermal activity underneath the ice, creating lakes and rivers below the surface.

The United Kingdom government has been urged to create a marine sanctuary around islands in the South Atlantic which are “virtually untouched by humans”. Fully protecting 500,000 square kilometers around the South Sandwich Islands would preserve wildlife including penguins, seals, seabirds and whales, conservationists said.

Thousands of Adelie penguin chicks died in Antarctica early this year, in an event now prompting conservationists to call for the urgent protection of east Antarctic waters. Scientists studying a colony of more than 18,000 pairs of Adelie penguins in the French Antarctic territory, Adelie Land, discovered only two chicks had survived at the start of 2017. The rest of the chicks had starved.

Argentina’s losses on its oil and gas assets, as well as its labor disputes, have prompted China’s Sinopec to consider selling its operations in the country.

A team of cartographers at British Antarctic Survey (BAS) has re-produced a high-resolution updated map of the sub-Antarctic island of South Georgia.
