Antarctica, Marine life, Brunt Ice Shelf, Iceberg : Scientists startled by wealth of life under iceberg the size of Bedfordshire
Exposing an environment hidden under the ice for the last 50 years snapshots show the iceberg a 74 measuring 490 square miles. The size of bedfordshire county splintering from the brunt ice shelf. Researchers aboard the german polisten icebreaker were then able to slip into the gap between the iceberg and antarctic to conduct their research. Their seafloor cameras photographed a fascinating world of alien. Looking mollusks, sponges and anemones.the creatures have been thriving under a 490 feet. Thick 150 meters cover of ice, some 18 miles, 30 kilometers below the surface.the finds were announced last week by scientists from the alfred wagoner institute helmholtz center for polar and marine research. Aoe coma.the polar researchers said in a statement. The first images from the seafloor reveal an amazing level of biodiversity in a region that was covered by thick ice for decades.one of the incredible photos: showcases a 10 centimeters sea anemone attached to a rock on the sea floor. These creatures, typically feed on shrimp and small fish.another image, shows the twisty tendrils of a brittle star starfish raised up to catch prey dot in another picture, a pink sea worm can be seen expelling a coiling line of fecal trail among a scattered collection of rocks corals And sponges.most of these animals are filter feeders, although it is unclear whether they feed on the remains of algae or organic particles carried on the ice dot. The researchers also came across at least five species of fish and two squids.
although thrilled at their discoveries. The researchers did not stop at just taking photos. The scientists collected sediment samples from the seafloor which they believe will provide more insight into the ecosystem.in particular the researchers are hoping to learn more about how antarctica has been responding to climate change.tanya karlixek. The german federal research minister said it is a unique opportunity offered to researchers on board polarston to explore the antarctic ice. Sheet.I am grateful to the crew of the polistan for taking on the associated hardships and also risks. Polar research makes a decisive contribution to better understanding and foreseeing climate change and its consequences for our earth.we need this knowledge in order to be able to take effective counter measures against climate change.the effects of climate change in antarctica, among others, are worrying.the. West antarctic has been particularly affected by rising temperatures worldwide with east antarctica. Yet to experience global warming.climate models, however, suggest temperatures will start to rise in the east antarctic this century. According to the aoe scientists, the antarctic is already losing ice at higher rates than before 2021.. Hartmut helmer, a physical oceanographer and he expeditions leader, said it’s extremely fortunate that we were able to respond flexibly and explore the carving event at the bronte ice shelf in such detail.that being said, im even happier that we successfully replaced a number of moorings which will continue To record elementary data on temperature, salinity and ocean current directions and speeds once we’ve left.this data forms the basis for our simulations of how the ice sheet will respond to climate change.
icebergs, the size of a74 only break off or carve every 10 years or so.but.
