Stunning Antarctica sea creatures discovered after detachment of the iceberg
Ice ice cream has exposed a region that that they had never seen before through human eyes, revealing a living, flowering ecosystem
A big sponge, a cluster of anemones and a special life could be seen almost 230 meters deep in the sea DNA area, which was recently covered with the George VI ICE shelf in Antarctica. Sponges can grow very slowly, sometimes lower than two centimeters a 12 months, so the size of this specimen suggests that this community has been lively for many years, and possibly even a whole bunch of years.

In relaxing science fiction hp lovecraft In the mountains of madness, A gaggle of researchers reveals the ruins of ancient foreign civilization during exploration at Antarctica. Now the real team has examined what’s under some frozen ice of the continent, and its discoveries are actually unearthly.
Scientists on board the Schmidt Ocean Institute Falkor (also) He sailed to Antarctica to explore the nearby bottom of the sea, the creatures living there and the way the climate change affects the Antarctic ice and ecosystems that evolved around it. But their plan stayed aside after the ice cream chicago from a close-by ice shelf in the Bellingshausen Sea on January 13.

This event was a chance that was too good to go: a probability to explore the sea bottom below the original location of the iceberg – like overthrowing the rock or logs in the forest to see what creatures lie hidden underneath. “There was a sense of entering the complete unknown,” says co -chairman of the expedition of Sasha Montelli from the University College London. “We thought we could see some life there, but it was really surprising to see the degree in which life bloomed in such a hostile environment. And it was not only there, but apparently it was kept for a very long time.”
Scientists sent underwater underwater work in the depths and located an ecosystem crammed with bundles that seem like dr. Seuss, in addition to sea, ice spiders, octopuses. Some creatures which are recent species, and plenty of can only be found near Antarctica. In addition to being just distant, the continent has been isolated for hundreds of thousands of years by Antarctic round current, which surrounds him like a moat around the castle.

The tentacles of lonely waterwood drift in a depth of 360 meters in the seabed area, which was recently covered with the George VI ICE shelf. Lonely waterids are related to corals, jellyfish and bundles, but they don’t form colonies.

“Because the Bellingshausen Sea is not very tested in terms of deep biodiversity, we expect many new species from the expedition. In fact, we have already confirmed some, including snails, polyichete worms, crustaceans and even fish,” says the scientist of Patricia Esquete of Center for Eventational and Marine Studies in Portur.
Researchers also encountered large wreath sponges, the size of which indicates at their age. “Based on the size of animals, the communities we observed, have been there for decades, and maybe even hundreds of years,” said Esquete in Last press release.
Observations attract a pointy contrast with previous ecology studies below ice, which either dropped the cameras through the ice holes or years after the clamping of the iceberg took place. “These studies have shown that ecosystems seemed quite impoverished, with a limited number of species,” says Esquet. “We now know that under the ice shelves, at least in the first 15 kilometers from the front”-the unveiled area of the recent expedition scientists were in a position to explore after an ice cream-“there are various, justified ecosystems.”

It is less certain how this live ecosystem will have the option to do now when the icebergs have broken off. Many deep -sea residents are adapted to unchanging conditions occurring of their environment, in order that they are very sensitive to even small environmental changes. In the case of life forms discovered in the Bellingshausen sea, the dramatic loss of their former ceiling of the iceberg may shake the ecosystem.
Montelli says that the floating ice shelf, from which the iceberg broke away, withdrew inland by about 25 miles (40 km) in the last 50 years – simply one example of accelerating ice loss on the continent. “The loss of ice from the Ice Antarctic is the main factor contributing to the growth of sea levels around the world,” said Montelli in the last press release. “Our work is crucial to ensuring the long -term context of these last changes, improving our ability to design future changes.”
