Antarctica has no owner and no country can lay any claims on the continent. However, Antarctic bases are under the jurisdiction of the appropriate country making these remote places always a bit like the homeland. Recently, penguins living near the Australian Antarctic station Davis became witness of an unusual ceremony: The Australian Citizenship Ceremony.
The melting of Arctic sea ice during the winter of 2015/16 had received immense media attention. Several causes had been debated and many saw global climate change as the main culprit. But now, researchers at the ETH Zurich found unique weather anomalies to be the main causing factor. Yet, the researchers have not given an all-clear-signal.
Tourism in the Arctic is a fast-growing branch within the cruise industry. However, this also increases the potential risk of accidents and incidents as not all ships are equally suited for visits to the Arctic. Now, Cruise industry, authorities and researchers will join forces to enhance Arctic SAR through the new ARCSAR network. Having secured €3.5 million in EU funding, the ARCSAR project will run for five years and include a live exercise on a cruise vessel.
To find fossilized remains of dinosaurs in Antarctica is quiet difficult not only due to the conditions. Because of the glaciation that had started 40 million years ago, most of any fossils have been washed into the ocean. Ironically, also remains of marine dinosaurs also found their way back into their original habitat. However, near the Argentine station Marambio on the eastern side of the Antarctic Peninsula, scientists now found the fossil of a huge plesiosaur.
During WWII and the Cold War era, Greenland was in the focus of western military strategists due to its proximity to Russia. Agreements between Denmark and the USA allowed the establishment of US military bases on the world’s largest island, even under the icecap. At the end of the conflicts, most of the base were abandoned but not cleaned up which led to a debate between the Danish and the Greenlandic governments. Now, the two parties signed an agreement to finally conclude the quarrel.
Southern right whales long had suffered from unchecked exploitation in the early days of industrial whaling. Especially around the subantarctic island of South Georgia, whalers quickly had decimated the slow, fat animals. Since the whaling ban in the 70ies, however, the species made a comeback. Now, an international team of researchers led by British Antarctic Survey (BAS), travels to the sub-Antarctic island of South Georgia this month (January) to carry out the first scientific whale survey and to check the status of this whale species.
With the arrival and unloading of the EDEN ISS greenhouse at the edge of the Antarctic ice shelf, the construction process has begun. In the coming weeks, a team from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) will set up the greenhouse, designed for extreme environments, just 400 metres from the German Neumayer Station III in the Antarctic. It will be run by the Alfred Wegener Institute (AWI), which is working on the EDEN ISS project together with DLR.
While the Trump administration is currently trying very hard to undo the protection measurements in its Arctic areas, Canada goes the other way. Last year, on December 21, the Federal government announced the establishment of seven new marine refuges along the coast of Nunavut and Newfoundland. Altogether, the marine refuges will be more than 145’000 km2 of ocean and will increase add another 2.53 percent to the Canadian protected areas.
Penguins are iconic birds for the Antarctic. However, more than half of all species have always lived outside of the Antarctic boundaries for millions of years. Thus, fossils of these special birds are found in many un-penguin-like places like Australia, Chile or New Zealand. Here, scientists have unearthed another previously unknown early penguin species, Kumimanu, Maori for “monster bird”.
Researchers from the Canadian Museum of Nature and the Natural History Museum of Los Angeles County have identified remains of a 3.5-million-year-old bear from a fossil-rich site in Canada's High Arctic. Their study shows not only that the animal is a close relative of the ancestor of modern bears -- tracing its ancestry to extinct bears of similar age from East Asia -- but that it also had a sweet tooth, as determined by cavities in the teeth.
