The Antarctic Environments Portal provides ready access to high-level summary information on Antarctic issues, based on the best available scientific knowledge. SCAR’s primary aim in hosting the Portal is to fulfil its remit of providing objective and independent scientific advice to the Antarctic Treaty System on issues of science and conservation affecting the management of Antarctica and the Southern Ocean. We are excited to have launched a ‘new look’ Portal website which has been redesigned to make it easier for users to find the information they want and to access additional resources. The Portal’s Information Summaries have also been designed to make them more user-friendly.
