There is a world teeming with life beneath Antarctica

A group of researchers from the universities of Wellington, Auckland and Otago, but also the National Institute of Water and Atmospherics and the department of geological and nuclear sciences traveled to Antarctica a few days before the eruption of the Hunga Tonga-Hunga Ha'apai volcano, in Tonga.

The eruption would have caused a significant pressure change and tsunami. Researchers marveled at an incredible corner of the world, observing the real-time influences of events about which virtually everything is known. This incredible corner of the Antarctic is located near the Ross Barrier, the largest ice shelf in the South Pole which is located in a territory claimed by New Zealand.
In a large area of ​​Antarctic ice, many shrimp-like animals have been found, which inhabit an underwater ecosystem.

There is a world teeming with life beneath Antarctica

This lost world can also be explored due to climate change and consequent global warming, which have led to an Antarctic record in terms of temperatures. After drilling some holes, they realized that under the ice there were many amphipods, small creatures that are part of the same family as lobsters and crabs.

The specimens measure approximately 5 millimeters. It is not the first time that something mysterious has been discovered in this part of the world, such as the lakes identified some time ago by NASA, while this time we have stumbled upon a microworld.

The various detection tools were left on the platform to get new information about the ecosystem that could rewrite the history of Antarctica. In particular, we need to understand what makes the water so unique in the ice we are talking about.

The seas are very rich in zooplankton and Antarctic krill. Krill, in turn fed by a few species of algae that make up phytoplankton, is the food of fish, whales, seals and sea lions, penguins and numerous sea birds. Four species of penguins live and reproduce on the pack ice: the emperor penguin, the Adelie penguin, the Pygoscelis papua and the Pygoscelis antarcticus.

Another thirty species of birds reproduce in the Antarctic continent, among these are the royal albatross, the snow petrel, the Antarctic fulmar, the last two nesting in the snow-free parts, called nunatak, of the mountains of the interior. , going inland up to 100 km from the coast.
