Antarctica is the fifth largest continent in the world. Temperatures can drop below -90 ° C in this icy continent and are therefore of great interest to the scientific community that studies its history. Between 1,000 and 5,000 people live in the frozen desert and the number of animals is scarce. Penguins and seals are among the most common observations.
However, a group of scientists was trying to gain a better understanding of what's under the ice.
Amazon Antis "Antarctica – an adventure of another nature" revealed how a team drilled deep into the ice cap and the ice-cold water.
" Here, the Antarctic hides its color and complexity, and in the forests of small plants called algae, the ice grows like a greenhouse.
Antarctic scientists dug 6 feet into the ice

This life chain is so isolated and balanced that scientists find clues to the health of the whole planet
" Millions of krill that like small shrimp are eating the algae.
"Fish eat the krill and seals eat the fish. "
The cameras swiveled around the deep waters, revealing a living space that shines with life before the narrator showed how important this dive was.
s scientists point to the health of the entire planet.
"Here you dive under water for the first 20 minutes, then it gets dangerous."
They drilled into the ice plate
The scientists were baffled
Earlier, scientists from the ice had made an equally amazing discovery about the history of our planet of Antarctica.
The group drilled a nearly 500 feet into an ice sheet to learn how the global Warming affected the region during the same documentary.
The documentary spokesman added, "Ice sheets can read Like the rings of trees and the climate record goes back 100,000 years."
"Prisoner air bubbles from ancient air – the ice cores tell one simple story.

You can only spend 20 minutes under the ice
"When the carbon dioxide content in the atmosphere changes, so does the climate.
"The news from Antarctica is bad from the crystal of ice.
"Methane, strontium 90, lead, increased carbon dioxide, we change the air and we can see the effects."
In May 1985, Joseph Farman, Brian Gardiner and Jonathan Shanklin observed a decline. The polar ozone was far greater than assumed.
The discovery of the ozone hole was initially rejected as unreasonable, but later studies showed that the concerns were valid.
Since 1991, the United Nations Environment Program has sponsored a number of technical reports on the scientific assessment of ozone depletion to reverse the effects.
In 2007, a report was released showing that the hole in the ozone layer recovered and was the smallest hole in about a decade.
The 2010 paper states: "Over the past ten years, global ozone and ozone in the Arctic and Antarctic has not dropped, but is not rising yet.
"The ozone layer outside the polar regions is expected to recover its pre-1980 levels before the middle of this century.
The temperaments may be below -90
Antarctica is of great interest to scientists
"In contrast, it is expected that the spring ozone hole will recover much later over the Antarctic. "
In 2012, NASA confirmed that the hole had narrowed again.
They revealed: "Higher temperatures over the Antarctic led to the second smallest ozone hole of the season for 20 years, averaging 17.9 million square kilometers, reaching its maximum size on September 22, reaching 21.2 million square kilometers."
