Inter-annual dynamics of changes in hydrooptical characteristics of ecosystem of the Yenisei basin

摘要

The seasonal variability of hydrooptical and fluorescent characteristics from the coastal waters of the Yenisei river have been studied. The work was estimated chlorophyll content, photosynthetic activity, concentration dissolved organic matter (DOM) and mineral component. The data have been obtained from series of regular observations in the coastal waters of Krasnoyarsk during 2012-2014. During year the chlorophyll "a" concentration and mineralization varied 2 times for warm and cold seasons. Regression analysis revealed relationship between coefficient synthetic activity and concentration of chlorophyll "a".
