Abstract
The results of the first comprehensive limnological experiment conduct ed in Lake Onega in the summer of 1989 are presented. The concurrent s paceborne observations (Cosmos-1870 SAR), airborne surveys (visual obs ervations and IR radiometry), and shipborne observations (visual obser vations, thermal and optical water characteristics), made it possible to establish the presence of vast regions of phytoplankton in the lake . It is shown that the activity of phytoplankton may change water surf ace conditions, thus causing strong radar signal contrasts.
