Russian scientists will test a new device for measuring Arctic ice thickness

Scientists from the Arctic and Antarctic Research Institute (AARI) at the "Ice Base of Cape Baranova" will test new device that allows measuring the thickness of sea ice at the Cape Baranova ice base. This was announced by the press service of AARI on Monday.

"A new acoustic wave recorder, developed by the scientists of the Institute of Applied Physics will be teated at the Cape Baranova ice base. This version of the device is now being prepared to be sent to a research centre", says the message of the press service.

The research of sea ice with a wave scanner has been carried out in the Arctic by scientists of the AARI and IPP RAS for three years. The first acoustic device has been used at the ice station in 2019. But it turned out that this version of the device made some inaccuracies while dealing with the melting ice. 

"The new device will be able to solve this problem, as it allows to measure the ice thickness in any natural conditions. The principle is simple: the recorder is hanged on on the rope and lowered into a wide hole in the ice; the signals are sent from the lower and upper limits of the ice. The maximum depth of immersion is about 300 meters. As a result, scientists get continuous reliable data on the dynamics of ice thicknes", says the report.
