They see a “fertile” environmental system hidden under the Antarctic snow base

Spiders -Oo GiantsSnow fish and endless organisms usually live in a skilled environmental system on an icy platform that is not inaccessible, which is until last January. I was hidden from a great iceberg.

An international group on the ‘Balcore’ research ship from the Schmid Ocean Institute was traveling through Antarctica earlier this year Biological links between ice and seaWhen a wonderful and unexpected opportunity was provided.

On January 13, the iceberg of Chicago’s size A-84 It is divided George vi. It is a frozen site that occupies the George VI channel, which separates Alejandro I Island from the West Coast from the Antarctic Peninsula. “We are using this moment and changing our travel plan to see what happened in the depths,” says Patricia Escut of Aviro University (Portugal). “We do not expect to find a beautiful and prosperous environmental system like this. Due to the size of the animals, the communities we care have been decades. Maybe even hundreds of years.”

What did scientists invented under the giant glacier?

This group moved to the hole that its original task in the Beltingshausen Sea moved into the hole, became the first men who inquired about a part Until then, it is inaccessible.

Scientists have conducted the first comprehensive study of geography, physics, maritime and biology in the area covered with a very comprehensive and floating ice site. It is equivalent to about 510 square kilometers. With a distant directed vehicleThe group was able to look at the background and sea walls for eight days, and found prosperous environmental systems at a depth of 1,300 meters.

There are among the findings Large coral reefs and sponges It supported a wide variety of animal life. The group suspects that many new species are hidden between them, although it will take years to determine it.

How does life survive under the layer of floating snow?

Is not much known about what lives Under the floating snow sites of Antarctica. This trip was first used as a A vehicle that can sink in the distance restricted water (ROV) Explore this remote environment. The device provides new perspectives about the activity of life to live together in that depth.

Deep water organisms usually depend on the fall of nutrients from the surface to the sea, the marine company Schmid explains. However, these Antarctic environmental systems have been closed for centuries 150 meters thickThe surface is completely isolation of nutrients. Currents The group suggests that they also go with nutrients, and they can be a possible way to maintain a life under the ice layer.

“Lucky moments are part of the emotion of the sea: they give the opportunity to be the first person to see the beauty of our world,” he says GeoticaSchmid Oceanic Institute Director. Although marine researchers are the object of dreams, the circumstances surrounding the iceberg are worrying.

Invemia The iceberg is a normal phenomenon on snow sites. But the Climatic change This accelerates the process, which reduces the snow layer in the recent decades. “Snow losses from the Antarctic snow are greatly contributed to the increase in sea level globally,” says Sasha Mandelly, a scientist and member of the University of London University (UCL) University of the United Kingdom.

International Group formed by Scientists Chile, Germany, Norway, New Zealand and the United StatesIn the past, it has also taken the opportunity to collect data on the behavior of the ice layer. Researchers used other autonomous submarines known as Glyders to study The impact of the iceberg in the area.

The preliminary data indicates the “high -biological productivity” and the strong flow of the dissolving water Wardrobe ice George IV. “Our task is essential to provide the long -term environment of these recent changes, improves our ability to make future changes, and predicts that are the basis for potential principles,” Mandelly says. “There is no doubt that we will make new innovations because we continue to analyze these important data,” he added.
