As it happens5:29Scientists believed that the floor of the Antarctic Sea would be barren. But it is called life
When the staff learned of the ocean's science expedition that the iceberg was broken by the ice shelf of Antarctica, they knew they had to stop what they do right away.
After all, it was a unique opportunity to study the sea floor in the ocean area that was previously cut to people.
Despite their excitement, the team on the ship of the Shmidt Institute of Ocean did not think they would find a lot of life under the ice much more than the sun.
It turns out they were dead wrong.
The first picture, which came to the ship's management room, the team remote from the car, revealed a large sea sponge, on which the crab creeping shrimp said that the chief scientist of the expedition at the time of the discovery.
HotspentIt was a lot of excitement, “he said As it happens Host Neil County? “After that, we saw more hours and day day.”
Esqurete and his colleagues show surprisingly in the lush and diverse school ecosystem, which includes coral, sponges, fish, giant sea spiders, octopus, etc., are probably new to science.
But it remains a mystery of how much it could flower the depths of the dark ocean, about 1,300 meters, one of the ice slabs, one of the ice ice glaciers on the Antarctic Peninsula.
It is also clear what will happen to this ecosystem now, which has been completely changed from the loss of that ice.
“It's a very interesting discovery, and I can't wait to see all the new types found and understand what the biodiversity is in these ecosystems,” said Gwadalupe Bribiska-Revers.
The university of Aviro University in Portugal is a taxonomy, and the staff studied the bottom of the ocean of the Sea of the Antarco Peninsula in January, when they saw the new iceberg from George VI.
“We immediately knew we had to go there and study that area,” he said. “Our expectations were a very poor ecosystem, as you know, usually the sea ecosystem is fed by the energy of the sun.”
It is true even in the deepest depths, as nutrients from photosynthesis are slowly raining to maintain the ecosystems below.
But for centuries, this region was covered with ice, almost 150 m thick. Before that, the ice was so dense that touched the ocean floor.
“It means that the photosynthesis cannot happen … And food is not going to be produced,” Escet said. “Thus, we were waiting for some of the ways of life that fed with foods that were moved by streams, but we didn't expect much.”
If food and energy are not raining above, what is nourishing and feeding this region, which is called?
“It really will be the most impressive study we can do,” Esshet said.
The team gathered images, as well as some samples and geological designs. Scientists will affect the geology of the region, as well as the ocean currents, try to remove the puzzle. “How does the whole system work?” He said.
But the first step, says Esquete, it will categorize all the creatures they have seen.
“Thus, the complete morphological study of all the types we have found, and then a genetic analysis,” he said.
He doubts that dozens of them can be new for science.
“We were in an area that was very little examined. And we know that when you study the deep sea when you sampling the deep sea, you always find new species. “
While the calf of the iceberg, when and where it does it, it was preferable for the staff, it did not leave anywhere. The ice sheet is melting decades and shrinks decades due to climate change.
Victoria Maritian Biologist Verena Tunnizi, who was involved in the expedition, was amazed at how this newly discovered ecosystem would change now when it is exposed.
“They have a very unusual opportunity to study a world that has been hidden under extremely thick ice for thousands of years,” said the Canadian research chair.
“This expedition is able to create a” initial “data collection. Original settlement and ecosystem. And how will the curtain get back now?
At the same time, Esqurete is excited to disguise several sea tips.
“What makes it possible that the mass of life is something we really want to find out,” he said.
