The Icefin probe passed through 20 meters of ice and 500 meters of seawater to the Antarctic sea floor.
Tencent Space News According to foreign media reports, a research team assembled a detector called Icefin and passed it through 20 meters of ice and 500 meters of seawater to reach the Antarctic sea floor. This is the first time that this type of robotic probe has sneaked into the deep water under the Ice Ice Shelf in Antarctica and brought back video footage of life on the ocean floor.
Britney Schmidt, an assistant professor at the Institute of Earth and Atmospheric Sciences at the Georgia Institute of Technology, said: “The detector we built is a hybrid of a small detector and a marine submersible that can pass through boreholes in the Antarctic ice.†Icefin Detector The techniques used can also be used to search for life on other planets, such as Europa. The icy ocean of Antarctica is very similar to the liquid ocean of Europa.
Schmidt said: "At the same time, we need to better understand the ocean system in order to explore Europa. We are also continuing to develop and perfect these technologies, which will eventually give us a more realistic understanding of the polar region and even Europa." A scientific device carried by the detector enables it to measure the ocean conditions under the ice.
A team of scientists and engineers at Georgia Tech assembled this unmanned diving device at Antarctica. The team hopes that the Icefin detector will land on the Arctic for the first time in the summer of 2016 and return to Antarctica in the fall. The Icefin Explorer's exploration of the environment under the Antarctic ice shelf and the recorded video will help us understand how the Antarctic ice shelf is changing under global warming conditions. It also helps us understand how organisms survive in a cold, frosty environment.
The team leader, Mick West, a research engineer from Georgia Institute of Technology, said: "The distinguishing feature of Icefin that truly distinguishes it from other submersibles is that it is quite slim and has all the sensors scientists need. Its instruments can be used for navigation as well. Can be used for scientific exploration, which is not available in other submersibles."
The deepest seawater in the Southern Ocean reaches 5,000 meters. Icefin can reach a depth of 1500 meters and explore 3 kilometers. Submersibles of the same level as Icefin can only sneak into sea water several hundred meters deep. Icefin's video shows a stunning shot of the 500 meters below the Ross Ice Shelf.
Schmidt said: “We have seen in the video the complex underwater ecosystem that we have never seen before, and the details of the ice-to-ocean interface that we have never seen before. The biologists at McMurdo Station were very surprised. The amount of ecological resources at this location includes creatures such as starfish, sponges, and sea anemones."
