Paper Abstract

The results of simultaneous lidar monitoring of phytoplankton (PP) and organic matter (OM) horizontal distributions in the subsurface layer of the Baltic Sea are presented in the paper. A special shipboard lidar system has been developed. Total length of the monitoring route was 8390 km. The horizontal distributions of near-surface PP and OM for the second half of May and the first ten days of June were reconstructed using the data obtained. The polluted areas near the industrially active regions were detected. Diurnal rhythms of PP fluorescence were measured in situ by lidar. It proved the necessity of adjustment of lidar data for such diurnal variations. The temporal divergence of detected structures was explored. For most parts of the area, averaged time of divergence for phytoplankton horizontal distribution was estimated as 1.2% per day.
