FIELD: physics.SUBSTANCE: system includes sub-satellite (shipborne) and satellite means of measuring oceanographic characteristics. The sub-satellite measurement means are represented by four sets of measurement sensors and integrated measurement devices, the first (1) of which is mounted on the bow of the ship underwater, and the second (2) on the bow of the ship above the water, the third (3) on-board the ship, the fourth (17) on a carrier (18) in the form of a probe linked to an anchor-buoy line device (19). The first (1) set consists of sensors for measuring temperature, electrical conductivity and pressure of the seawater, oxygen concentration, light scattering coefficient in the water, a device (12) for collecting overboard seawater, a multibeam echo sounder and side-looking sonar. The second (2) set consists of sensors for measuring temperature, humidity and atmospheric pressure, direction and speed of wind, a device for measuring fluorescence of phytoplankton and dissolved (yellow) organic substance, a device for measuring radiant temperature of the sea surface, a device for measuring spectral brightness of the sky, the sea and irradiation of the sea surface with solar radiation. The third (3) set consists of a device for measuring spectral attenuation of light in the seawater, a device for measuring fluorescence of phytoplankton chlorophyll and the dissolved (yellow) organic substance, a device for measuring concentration of chlorophyll and the dissolved (yellow) organic substance, a device for measuring concentration of carotenoids, pheophytin and carbon. The fourth set (4) consists of a device for measuring vertical profiles of dissolved methane, content of alpha-, beta- and gamma radioactivity nitrates, the zonal and meridian components of the flow speed and sound speed in the seawater. The satellite measurement means include a lidar, which comprises a red and green range laser, a device (6) for determining coordinates of the ship, a device (8) for determining coordinates of the beam for scanning the water surface with an artificial Earth satellite. Readings of the sub-satellite measurement means are used in correcting satellite data in a device (11) for correcting satellite information and storing oceanographic data.EFFECT: high reliability of determining oceanographic characteristics and detecting spatial distribution thereof.2 cl, 1 dwg |
