Scientists of the Far Eastern Federal University (FEFU)
together with colleagues from the Harbin Engineering University (China)
are developing the world’s first technology of subglacial communication
for exploration and production of oil and gas in the Arctic region, the
FEFU reports.
“In order to master the Arctic, we must first gain a foothold in
shallow areas … The spread of elastic waves in the shallow sea is a
problem for scientists around the world.” By combining the physical
methods of Russian researchers with information processing technologies
of Chinese colleagues, we will be able to achieve a breakthrough in the
development of the Arctic zone, ” Professor Vladimir Korochentsev, Head
of the Instrument Engineering Department at the Engineering School of
the Far Eastern Federal University.
In Novik Bay on the Russian island in Vladivostok, a unique
experiment was conducted to study the new Arctic technology. It used the
developed by scientists FEFU pneumatic sonar radiator, sound waves
which propagate in water and on ice, as well as lens receiving antennas.
Harbin researchers brought high-precision seismic receivers to measure
the vibration of ice.
According to Korochentsev, preliminary observations showed that ice
absorbs about 95% of sound and is the main conductor of hydroacoustic
signals. The data obtained in the course of the joint experiment is used
for further scientific work on the development of ice-making
technologies.
