Abstract:

Based on multi-year (1924-1995) observations of Secchi disc, the variability of water transparency in the Karkinit Bay is studied. According to the peculiarities of transparency field formation, five regions in the bay are distinguished, for which the estimations of seasonal and intra-annual variations of Secchi disc visibility depth are obtained. Good characteristic correspondence of seasonal and intra-annual variations of transparency and biooptical parameters (chlorophyll a concentration, particle backscattering and total absorption coefficients), which are determined according to satellite data of colour scanners CZCS (1978-1986) and SeaWiFS (1997-2009) is shown.

Keywords:
