Distant assessment of concentration of the chlorophyll in the polluted water basins

Now the considerable proportion of the terrestrial population is located in coastal zones of the seas, oceans and lakes. Anthropogenous impact on various water basins in these inhabited zones exerts the negative impact on functions of local ecosystems and demands operational assessment of their state. One of efficient methods of monitoring of a condition of ecosystems is remote sensing. It should be noted that extent of pollution of reservoirs of Chla can reach (9 ¸ 10) · 103 mg/m3. It causes emergence of a number of the specific phenomena, such as saturation and wide spacing of gaged parameters. The authors describe an easy and efficient way to assess the concentration of Chla with the use of shift longwise effect of the wave of maximum reflective range of l » 700 nanometers. According to the carried-out analysis, from the point of view of achievement of high value of the relative sensitivity, the most expedient site is the site in the position of a maximum P » 715 nanometers; Р
