The approach of selective excitation of phytoplankton pigments has been applied to investigate the small-scale spatial inhomogeneities of phytoplankton distribution over the water basins, including stratification, and to produce the maps of various phytoplankton groups. The comparison of lidar and sampling data revealed the difference in remote data calibration when sensing the mixed phytoplankton community or the community with expressed dominant species.
The UV excitation channel of FLS-lidar has been used to map oil pollution in sea water onboard aircraft. By using the difference in spectral shapes of returned fluorescent signals recorded by gated multi-channel detector, the trace amounts of oil pollution were detected
The future development of the techniques for shipboard and airborne application is discussed. The field data of remote sensing of organic pollution, DOM and phytoplankton in the Baltic and Norwegian seas are presented.
