Hobart is the home port for the Australian and French Antarctic programs, and provides port services for other visiting Antarctic nations and Antarctic cruise ships.

Antarctic sea ice varies a lot year-to-year, but even by Antarctic standards this is well outside the bounds of normality.

The UK and Chile also agreed to continue close co-operation on Antarctic issues and to prepare a new UK-Chile Statement on Antarctic Co-operation.

This has also meant the official end of the Argentine Antarctic Campaign 2022/23, which takes place under the operational command of the Joint Antarctic Command.

Clara will join researchers at British Antarctic Survey with a project entitled “Exploring plastic waste removal options to minimize local introduction of micro-plastics in the Antarctic environment”.

The work in an "environmentally sensitive location and Antarctic conditions" requires the management of "significant safety and environmental risks," according to the Australian Antarctic Program.

However, Antarctica’s ice sheet — composed of the East Antarctic Ice Sheet and the West Antarctic Ice Sheet — is not a giant mass of stationary ice but rather a system with inputs and outputs of matter and energy.

They attribute the threefold increase in ice loss from the continent since 2012 to a combination of increased rates of ice melt in West Antarctica and the Antarctic Peninsula, and reduced growth of the East Antarctic ice sheet.

A major and permanent cooling step occurred between 14.8 and 14.1 Ma, associated with increased production of cold Antarctic deep waters and a major growth of the East Antarctic ice sheet.

By 1925, with the advent of the stern slipway in factory ships and the use of steam-driven whale catchers, the catch of blue whales, and baleen whales as a whole, in the Antarctic and sub-Antarctic began to increase dramatically.

Protector is a dedicated Antarctic patrol ship that fulfils the nations mandate to provide support to the British Antarctic Survey (BAS).

Shortly thereafter, the United States began its own program to search for Antarctic meteorites, operating along the Transantarctic Mountains on the other side of the continent: the Antarctic Search for Meteorites ( ANSMET ) program.

The exact opposite heating and atmospheric pressure anomalies occur during La Niña. citation This pattern of variability is known as the Antarctic dipole mode, although the Antarctic response to ENSO forcing is not ubiquitous.

The tasks of the Antarctic Treaty Secretariat can be divided into the following areas: * Supporting the annual Antarctic Treaty Consultative Meeting (ATCM) and the meeting of the Committee for Environmental Protection (CEP).

A false-color view of total ozone over the Antarctic pole is seen in this NASA handout image released October 24, 2012.

And so many of the places scientists find records of past climate conditions — in Antarctic ice or among tiny fossilized sea creatures in rock at the bottom of the ocean — seem so far away.

Antarctic sea ice has been growing sluggishly and staying at record lows for each month since April.

An update from the Scientific Assessment Panel to the Montreal Protocol confirms that the ozone layer is recovering, and ozone levels are expected to return to 1980 levels by around 2066 over the Antarctic.

A sea lion takes a siesta in the Antarctic sun.

British Antarctic Survey researchers looked at satellite images that showed the loss of sea ice at breeding sites, well before chicks would have developed waterproof feathers.
