The Australian scientists developed technology, allowing to watch the consequences of global rise in temperature on a sound. New method is the basis of circumstance that formation of cracks in glaciers unavoidable must be accompanied by loud sounds. In theory, they can be located through a sensible equipment. Investigated decided to avail for this purpose by devices which use for monitoring of nuclear explosions.As an object research scientists chosen the Antarctic glacier.
Measurings specialists conducted, being from him for thousands of kilometres. The submarine stations of supervision are located in the district of cape Levin in Western Australia and on the archipelago of Chagos in the middle of the Indian ocean. Every station is placed in natural ocean
acoustic channel. On such ductings a sound can travel on enormous distances, not co-operating with the surface of ocean and with a bottom.Scientists can analyse signals from the submarine stations real-time. According to authors, weekly they
get about hundred signals from the Antarctic glacier. Comparing of these information to information, got a sound-recording technique, set in Antarctic Region, rotined that the submarine stations indeed fixed the sounds of the Antarctic glacier.Scientists
assert that they succeeded to locate the seasonal changes of glaciers, however no certificates that a global rise in temperature violated the underlying structure of glacier, got by them it was not. However much authors intend to continue the experiment. In their opinion, measurings
conducted too not long and the collected information not enough in an order to do synonymous conclusions.In connection with the change of climate, uchenye-klimatologi is concerned by the state of arctic snow caps. While glaciologists did not come to single opinion in relation to speed
melting of arctic and Antarctic glaciers. The different groups of specialists get results, proving, that a danger is strongly exaggerated or, opposite, that the catastrophic melting began already, reports Lenta.ru.
