The result was a never-before-seen ecosystem in the underground river. The team of New Zealand scientists lowered the camera into a cave under the ice shelf, where they drilled a hole. As the camera sinks into the river, after a brief focus, numerous species emerge, including hundreds of shrimp-like crustaceans called amphipods. They found that dozens of different species thrive in a tiny patch of ocean floor beneath an ice shelf in Antarctica. For a place that has never been exposed to such creatures, the diversity of animals is astonishing. Scientists are beginning to question the habitability of the diversity of life, where the animals cannot be protected by the sun energy beam. The dark areas should not have sufficient food to support the diversity of life, because most of the ecological system is supported by photosynthetic organisms such as plants and algae, but now this phenomenon overcomes the theory for a long time.
Under such harsh conditions, the diversity of species is beyond scientists' imagination. Of course, it's one thing to find so much life beneath an ice sheet, but it's another to figure out why it's there, and the continental shelves of communities that scientists think live in the ice-free waters of polar seafloor aren't limited by a lack of food, so they end up with far more than they might need. Besides, they don't consume enough. These animals are attached to the ground and don't have a lot of tissue that requires a lot of energy, so they can survive on the small food that reaches them.
Moreover, carbon dating studies suggest that these seafloor creatures are not current inhabitants of the ice shelf beneath Antarctica. Whatever their age, life here must have been close to isolated for thousands of years, and there may be a correlation between the lack of disturbance and the richness of species in the environment. Storms, floods, and fires do not occur under the ice, enabling all to get the duration and stability needed for each open niche. However, these pristine environments may be among the first to disappear as humans drive climate change. If the Antarctic ice sheet melts, these rare ecosystems may be lost, and once gone, they cannot be recovered.
This discovery proves that there is a vast ecosystem beneath the ice, and it turns human biological theory on its head. As previously stated, Antarctica is known for its extreme cold, dry and frozen, 90 percent of the world's ice and 80 percent of its fresh water comes from this ice cap, which is part of the polar system. As a result, the continent has had a major impact on the rest of the world. To that end, scientists have made it their mission to learn everything they can about it.
Great discovery in Antarctica! Hidden for 100 million years, this mysterious continent is its own ecosystem
Antarctica is commonly considered the coldest and driest place on Earth, yet some life still exists there. The polar ice caps may be melting due to global climate change, but some in the Arctic are celebrating because a major discovery has been made in Antarctica! It is an unknown mysterious world!
The seemingly featureless frozen continent of Antarctica is characterized by whiteness, but it hides a mysterious and complex world that, according to researchers, could hold the key to understanding how climate change is affecting the planet. It's no secret that the Antarctic ice sheet is melting rapidly, with ice sheet glaciers melting six times faster than they did 40 years ago due to rising ocean temperatures, according to NASA.
Currently, Antarctica is losing 252 billion tons of ice a year, the equivalent of 3.5 Olympic swimming pools every second. The National Snow and Ice Data Center estimates that if all the ice in Antarctica melted, sea levels would rise by 70 meters, the equivalent of a 20-story building, enough to submerge every coastal city and wipe parts of the country off the planet. In fact, even a slight rise in sea level would be terrifying. For an area the size of Denmark could be destroyed at a mere ten metres of sea level, let alone near the sea.
Beneath this lurking danger, scientists have discovered a mysterious continent that affects the rate of melting in Antarctica. The ancient continent lies beneath an ice sheet twice the size of Australia. Ninety percent of Antarctica is covered by an ice sheet 1.8 kilometers thick. The ice sheet is the result of numerous years of formation, but the continent remained over Antarctica for about 100 million years without freezing. The continent had a warm climate, lush rainforests, and dinosaurs foraging in dense foliage, considerably better than modern New Zealand at the end of the Eocene and beginning of the Oligocene.
Since then, the climate has changed significantly. The ice sheet has been covered despite the effects of the greenhouse effect, East Antarctica, West Antarctica and the Antarctic Peninsula continue to cool, forming the three parts of today's Antarctica, each with its own distinct geographical location. For example, the ice of the Antarctic Peninsula hides a ridge jutting northwest from the interior of the continent, the largest regional mountain range in East Antarctica and some lowlands, of which the highest peaks of the 1,100km-long Gambit Sev Range, which is about the size of the European Alps, reach up to 3,000 meters and are mostly covered in ice.39bet-xsmb-xổ số tây ninh-xổ số binh phước-xổ số binh dương-xổ số đồng nai
During the last ice age, nearly the entire surface of West Antarctica was below sea level. The weight of the moderately thick ice pressed down on the bedrock, creating the ocean bowl beneath the area. With no land beneath West Antarctica, the region is more vulnerable to melting because it lacks the ridges that help keep the eastern glaciers stable. Satellite data collected between 1996 and 2006 showed faster melting in west Antarctica, but thinning of floating ice shelves connected to the ice sheet revealed a land mass parked in east Antarctica. NASA's most accurate map of the continent, dubbed "SuperAntarctica," was produced in 2019, revealing previously unknown topographic features, such as broad ridges protecting glaciers that flow through the TransAntarctica Mountains, which separate East and West Antarctica.
The map is a radar image created by combining measurements of ice movement with seismic data. Despite major advances in subglacial geological mapping, numerous parts of Antarctica are still up in the air, and the spatially crucial prediction of ice movement accelerated by climate change remains poorly informed. Therefore humans still don't understand what lies beneath Antarctica. There has long been speculation about the possibility of flowing freshwater lakes and rivers beneath the Antarctic ice sheet, but recently, scientists gathered at a site in Antarctica and fully investigated it. They determined it was an underground river, then drilled a hot water hose 1,640 feet beneath the ice to melt it.
The result was a never-before-seen ecosystem in the underground river. The team of New Zealand scientists lowered the camera into a cave under the ice shelf, where they drilled a hole. As the camera sinks into the river, after a brief focus, numerous species emerge, including hundreds of shrimp-like crustaceans called amphipods. They found that dozens of different species thrive in a tiny patch of ocean floor beneath an ice shelf in Antarctica. For a place that has never been exposed to such creatures, the diversity of animals is astonishing. Scientists are beginning to question the habitability of the diversity of life, where the animals cannot be protected by the sun energy beam. The dark areas should not have sufficient food to support the diversity of life, because most of the ecological system is supported by photosynthetic organisms such as plants and algae, but now this phenomenon overcomes the theory for a long time.
Under such harsh conditions, the diversity of species is beyond scientists' imagination. Of course, it's one thing to find so much life beneath an ice sheet, but it's another to figure out why it's there, and the continental shelves of communities that scientists think live in the ice-free waters of polar seafloor aren't limited by a lack of food, so they end up with far more than they might need. Besides, they don't consume enough. These animals are attached to the ground and don't have a lot of tissue that requires a lot of energy, so they can survive on the small food that reaches them.
