Canada's northernmost federal weather and research station is scaling back some environmental measurements and possibly suspending some others for six months due to a staff shortage blamed on "unusually high" turnover, CBC News has learned. Scientists say that will leave a permanent gap in records needed to understand global climate change.
Despite international sanctions and record-low oil prices, Russia pursues a rather offensive plan of further developing oil resources in its Arctic region. This is gambling with high stakes. However, Russian authorities as well as Rosneft and Gazprom both are confident that the investements will pay off eventually.
Albatrosses sail the Southern Oceans almost effortlessly. Even though known for centuries, only now, engineers have developed a new model to simulate dynamic soaring, and have used it to identify the optimal flight pattern that an albatross should take in order to harvest the most wind and energy. They found that as an albatross banks or turns to dive down and soar up, it should do so in shallow arcs, keeping almost to a straight, forward trajectory.
Footage from penguin-mounted mini video recorders shows four species of penguin eating jellyfish and other gelatinous animals of the open ocean, a food source penguins were not previously believed to partake of, scientists report this month in the Ecological Society of America's peer-reviewed journal Frontiers in Ecology and the Environment.
October 1, 2017 marks the ten-year anniversary since the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) research aircraft Polar 5 began service. In that time, the Basler BT-67 has flown more than 1.3 million kilometres to fulfil essential scientific and logistical duties. In the course of 48 measuring campaigns, predominantly for atmospheric research and geophysics purposes, the airplane has landed on the Arctic sea ice near the North Pole, and at the South Pole.
An international agreement is now in place to give special protection to the area of ocean left exposed when one of the largest icebergs ever recorded broke free from the Larsen C Ice Shelf in July this year. The iceberg – known as A68 – is starting to move north, and it will leave behind a 5,818 km2 area of seabed exposed to open marine conditions. Much of this area may have been ice-covered since the last inter-glacial period around 120,000 years ago, providing a unique opportunity for scientists to study how marine life responds to this dramatic change.
This September, the extent of Arctic sea ice shrank to roughly 4.7 million square kilometres, as was determined by researchers at the Alfred Wegener Institute, the University of Bremen and Universität Hamburg. Though slightly larger than last year, the minimum sea ice extent 2017 is average for the past ten years and far below the numbers from 1979 to 2006. The Northeast Passage was traversable for ships without the need for icebreakers.
Australian expeditioners will have new wheels when they travel across Antarctica this summer, with an upgraded bus destined for Australia’s Casey research station. The new bus will share the name of its predecessor, ‘Priscilla’, named by expeditioners after the iconic Australian movie about a road-trip across the Simpson Desert by a bus of the same name.
On October 1 - 4, more than 90 representatives from the Arctic and Antarctic expedition cruise industry will gather in Iceland for the second AECO/IAATO Polar Field Staff Conference. The topic of the conference is evolution and new challenges in the polar tourism industry.
Previous news about possible life forms under the ice of Antarctica had been published over the last few years. A new study by scientists from the Australian National University now found further evidence for this hypothesis. Previously undiscovered animals and plants may live in warm caves under Antarctica's glaciers. Forensic analysis of soil samples from caves on Ross Island revealed traces of DNA from algae, mosses and small animals.
