Scientists at the National Antarctic Science Center have found out the age of the whale, the remains of which lie on Rasmussen Island
Scientists obtained the results of radiocarbon analysis of samples made in a laboratory in Poznan, Poland. And the age of the whale remains was determined, it is approximately 1350 years.
Kit died in the seventh century - "in the era of the Vikings and the Mayan civilization, three centuries before Princess Olga and Prince Vladimir."
Regarding the species, scientists have determined that this is a blue whale - the largest whale and generally the largest animal in the world.
A yacht sank in Antarctica
The yacht "Endless Sea" is the result of a wreck that occurred on the night of 7.04.2012 in Antarctica in Ardley Bay, in Maxwell Bay in the South Shetland Islands archipelago, in the same bay where the Russian Antarctic Station Bellingshausen is located. The yacht was on a mission to shoot a documentary about the nature of Antarctica, but got stuck in the ice. In 2013, work was carried out to raise the yacht from the bottom of the bay, and now she is under repair and preparing for her new expeditions.
NASA discovered hidden lakes under the ice of Antarctica
Using the powerful satellite ICESat-2, scientists have created a map of active lakes in Antarctica, which are covered with thick ice. From time to time, their contours and sizes change due to the ebb and flow of water.
According to scientists, there are approximately 130 active lakes in Antarctica. However, some of their sections rise and fall. As a result, this leads to the filling of these areas with water, or vice versa - the water leaves them.
Lake in the hills of Westfold
It was formed 8,000 years ago when the earth was raised by an isostatic rebound, capturing seawater. Today it is hypersaline, rarely freezing. 51 m below sea level the coastline is the lowest accessible land point in Antarctica
Traditional winter dive at Casey Antarctica station
Overwintering personnel use chainsaws to cut a hole in sea ice 80 cm thick. Water temperature: -2 ° C, air temperature: -9 ° C.
In Antarctica, it suddenly disappeared
The Great Lake
According to scientists, meltwater, which has long accumulated in a deep lake on the surface of the Emery Glacier, split the ice and quickly flowed into the ocean.
Water quickly seeped through the cracked glacier into the ocean.
After the "disappearance" of the lake in its place formed a depression - the so-called ice valley, which occupies almost 11 square meters. km.
The future of the valley, which suddenly arose, is still unknown. It is likely that there will continue to accumulate meltwater, which will flow into the ocean.
The world's largest iceberg broke away from Antarctica
Its area is over 4 thousand square meters. It is currently the largest in the world.
The iceberg formed on the western side of the Ronne Glacier shelf. Satellite imagery shows that it is 170 kilometers long and 25 kilometers wide.
The iceberg was spotted by the British Antarctic Service and later confirmed by the US National Ice Center with images from the Copernicus Sentinel-1 satellite.
