Для измерения показателя ослабления был разработан новый погружаемый прибор, дано его описание, алгоритм калибровки и оценка точности измерений. Приведены результаты измерения профилей показателя ослабления, температуры и солености воды в различных точках Баренцева моря. Проведены расчеты уровня эхо-сигнала и отношения сигнал/шум как функций глубины анализируемого слоя. Показано, что на всех станциях мощность эхо-сигнала достаточна для уверенного обнаружения гидрофизических неоднородностей.</p></abstract><trans-abstract xml:lang="en"><p>Lidar detection of hydrophysical nonhomogeneity, such as internal waves or turbulence, is possible if there is marked stratification of the depth profiles of attenuation coefficient and the fluid density, and if the lidar echo-signal from pycnocline area is sufficiently large. A new submersible instrument for attenuation coefficient measuring was developed and produced. In this paper we describe the instrument and the algorithm of its calibration and measurement accuracy estimation. The results of field measurements of attenuation coefficient, density and temperature depth profiles in 12 spots (stations) in the Barents Sea are given. Using the results of these measurements, we computed the echo-signal levels and the signal-noise ratio as functions of depth. It was shown that at all stations the echo-signal power is sufficient enough for hydrophysical nonhomogeneity detection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лидарное зондирование</kwd><kwd>показатель ослабления</kwd><kwd>гидрофизические параметры</kwd><kwd>Баренцево море</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lidar sensing</kwd><kwd>attenuation coefficient</kwd><kwd>hydrophysical parametres</kwd><kwd>the Barents Sea</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dolina I.S., Dolin L.S., Levin I.M., Rodionov A.A., Savel’ev V.A.
