Ma. Naumenko et al., ANALYSIS OF HYDROBIOLOGICAL CONDITIONS IN LAKE ONEGA BASED ON COMBINED SPACE RADAR DATA, AIRCRAFT DATA AND CONTACT MEASUREMENTS, Soviet journal of remote sensing, 11(3), 1994, pp. 515-528
The paper gives the results of the first systematic limnological exper
iment on Lake Onega in Summer 1989. It is shown that combined satellit
e (Kosmos 1870, SAR), aircraft (visual observations and IR radiometry)
and ship surveys (visual observations, recording of the temperature a
nd optical characteristics of the water) enable us to establish the pr
esence of vast areas of phytoplankton in the lake.
