Preliminary results of bio-optical investigations at Lake Baikal
The preliminary results of complex bio-optical investigations carried out at Lake Baikal in July 2018 showed high variability in the light absorption properties of all optically active components, as well as their relation with hydrophysical characteristics. Vertical distribution of chlorophyll a was characterized by the presence of a maximum near the bottom of the euphotic zone. In this deep chlorophyll maximum layer, there were specifc features of phytoplankton light absorption spectra reﬂecting the abundance of phycobilin-containing blue-green algae in the phytoplankton community.
