Scientists from the California Institute of Technology in search of the causes melting of Antarctic ice decided to involve in research robot dolphins. robots length of six feet within two months of swimming in the waters of the Southern Ocean, where they launched off the coast of Antarctica, regularly diving to a depth of about 1.2 kilometers. After the robots have returned to the researchers, scientists have detailed data on temperature and salinity.

Traditionally, such measurements are carried out with the help of special equipment, pulling their research vessels, or by using satellite data. However, such methods do not allow researchers to study in detail the process of melting glaciers. After the warm water, which scientists believe provoke melting occurring at great depths. In addition, the scientific interest in most cases are not available for shipping.

 

These circumstances pushed American researchers to create robotic assistant which could remain in water for a long period, monitor changes in temperature and ocean currents during a certain time interval. These devices operate on batteries, and swim by pumping and pumping fluid from different compartments, thus becoming either more or less dense than the water around them. With the help of original wings on the sides, the robots can dive to a depth and glide like a dolphin.
Thanks to the robotic data Californian scientists have unexpected conclusions. It was found that increasing the amount of warm water entering the ice shelves, causing underwater storms caused by whirlpools. In order to understand the effect of such transfer of heat in the long term, according to scientists need long observation.
In the future, authors, developers robotic dolphins plan to continue their studies and further bring them to another robot Waveglider, which runs on the glacier surface. The plans of the scientists - compare oceanic activity in the Drake Passage - between the southern tip of South America and Antarctica - the processes that occur on the surface, given the speed and direction of winds in the area. According to the study authors, this will allow them to obtain new data on the exchange of carbon dioxide between the atmosphere and ocean and shed light on the process of climate change on the planet.
