Australian students chance to fly to Antarctica

Australian parliament had decided to invest more resources towards their Antarctic program. To this end, the construction of a new icebreaker was decided earlier this year. To engage the population and increase popularity of its Antarctic program, the government also decided to start a school competition for naming Australia’s new Antarctic flagship.

How warming oceans impact Greenland‘s ice sheet

The mass loss of the Greenlandic ice sheet accounts for more than a quarter of global sea level rise. Scientists anxiously observe the increasing impact of climate change on the entire ice sheet.

Early meteorite hit near Falklands formed Earth’s largest crater

In the past, the Antarctic was hit by meteorites and meteors several times. Traces are found on Antarctica on several occasions rather easily. However, the subantarctic islands and surrounding oceans are harder to screen due to the depth of the basins. An international team of scientists now has found a large crater near the Falkland Island archipelago. They estimate the age of approximately 250 million years and consider it one of the largest craters in the world.

New research ships plans show cooperation between economics and ecology

It is said that economics and ecology seldom go hand in hand. However, Norwegian entrepreneur Kjell Inge Røkke and his family present a perfect example to prove the general opinion wrong.  Røkke has revealed plans for a brand new ice-strengthened research expedition vessel REV which will be built in cooperation with the World Wildlife Fund (WWF). According to the plans, the yet unnamed ship will be ready in 2020 to set sail.

Numerous icebergs drift along coast of Newfoundland

The coastline of Newfoundland in eastern Canada has received increased attention due to a large number of unexpected visitors. For weeks, a larger than usual amount of icebergs and drifting sea ice has been washed up along the shores of the islands. For tourists and locals alike, the bergs and ice pose a spectacular photo motive while sailors and International Ice Patrol worry about the impact on shipping lanes and marine traffic.

Volcanic eruptions decimated Gentoo colony near Deception Island

Gentoo penguins are tough generalists and are capable to withstand the harsh Antarctic climate. However, the tremendous force of volcanic eruptions, as had happened on Deception Island, had put colonies close to extinction several times over the last 7,000 years. This is the result of a study conducted by researchers from British Antarctic Survey (BAS), which they published recently in Nature Communications.

Russia’s latest military base opens its doors

The Franz-Josef-Land archipelago is the northernmost landmass and is part of Motherland Russia. Considered as the western gateway into the Northeast Passage as well as to the North Pole, it is strategically important to the government in Moscow. With the renewed interest in the Arctic and its resources by Russia, authorities had made the establishment of a military base on one of the archipelago’s islands the highest priority. Now, after 3 years of construction, the complex at Nagurskoye Base on Aleksandra Island has opened its doors and was visited by president Putin and a high profile delegation.

This year’s Antarctic sea ice 'obliterates' previous minimum record

Antarctica has about 10 per cent less sea ice this year compared to the previous record minimum - a stunning reversal after an all-time high was recorded in 2014. In March 2017 the sea ice extent around Antarctica has shrunk to 2.1091 million square kilometres.

Gene flow between bear species is easier than expected

The mixing or hybridization between polar and brown bears appears to be easier than previously expected. Senckenberg scientists have sequenced the entire genomes of four bear species, making it now possible to analyze the evolutionary history of all bears at the genome level. It shows that gene flow, or gene exchange, between species by extensive hybridization, is possible between most bear species - not only polar and brown bear. The DNA samples of different bear species came from different European zoos, underlining their importance not only for conservation, but also for research. The study published today in "Nature Scientific Reports" also questions the existing species concept in general, because other genome studies too have, frequently found gene flow among species.
