As climate change continues to impact the Antarctic, glacier melt and permafrost thaw are likely to make more liquid water available to soil and aquatic ecosystems in the McMurdo Dry Valleys, potentially providing a more nutrient-rich environment for life, according to a Dartmouth study recently published in Antarctic Science.
Approximately two years ago, a huge rift was detected on the Larsen C Ice Shelf on the eastside of the Antarctic Peninsula. Now, scientists have discovered that the crack has increased rapidly and only another 20 km of ice are left to crack before one of the largest icebergs ever recorded will be born. Satellite observations from December 2016 suggest that the iceberg with an area of up to 5,000 km² is likely to calve soon.
Being a penguin isn’t easy nowadays. Changing climate, overfishing, pollution are just a number of threats which make penguin life difficult. On Zavodovski Island, part of the South Sandwich Archipelage, a new threat adds to the list. A volcano erupting there is depositing ash over one of the world’s largest penguin colonies.
Antarctica holds many mysteries but a new one seems to have been revealed recently. Another large lake is hiding under its ice – second only to Lake Vostok in size. Today 370 subglacial lakes are known and they are of great interest because of the possibility that they could harbour unique life forms that may have existed in isolation, locked under ice for millions of years.
AWI glaciologist Dr Daniela Jansen and a team of British researchers have discovered a large rift in the Larsen C Ice Shelf in Antarctica which in time will dramatically reduce its area and could affect its stability.
The largest ever-conducted rat eradication program on South Georgia has reached a huge milestone last Monday. The helicopter transporting the last baiting bucket filled with the blue baits to battle the rat infestation, landed at 12.50 local time at the camp and thus finishes the baiting of the Southwest of the island. During three field seasons since 2011, more than 800 buckets with bait were distributed over an area of more than 1’000 square kilometers. Now a monitoring program commences to check the result of this mammoth task.
