AB An experimental techniques to estimate the influence of dissolved organic matter (DOM) on remote sensing of chlorophyll in water has been developed, based on the relationship between fluorescence and absorption of light by a substance. The profiles of fluorescence, chlorophyll content in sea water and estimates of light attenuation in water samples were used in the paper. These data have permitted to calculate the regressions linking fluorescence and light absorption at 450 nm by chlorophyll (ABC450) and by DOM (ABD450). The remote sensing needs no correction for DOM if M450 = 100* (ABC450/ABD450) much greater than 100. This technique has been applied to data collected during the international Skagex field experiment in the straits of Skagerrak and Kattegat in spring and autumn of 1990. It was found that M450 <= 100 everywhere in the subsurface layer. Unfavorable conditions for remote sensing of chlorophyll prevailed in the straits because of the uptake of DOM-rich water from the continent and the accumulation of phytoplankton in deeper layers. These and another processes can increase relative content of colored DOM even in waters of open ocean.
