Abstract
The composition and operation principle of an instrument for measuring the water extinction coefficient in real time are described, including measurements in water under the ice surface. Examples of instrument testing under field and laboratory conditions are given. The measuring instrument is recommended for estimation of maximal receiver-source distances when line-of-sight optoelectronic communication or communication on scattered laser radiation is possible.
