Measurements of chlorophyll depth distribution in Lake Kinneret (Israel) were carried out using a ship-borne fluorescent Light Detection And Ranging (LIDAR) operating in the frequency domain of 500-750 nm. Depth resolved remote laser sensing of chlorophyll in the upper 0-5.0 meters were carried out and heterogeneous distribution of this phytopigment was detected. Deep vertical profiles (down to 35 m depth) of chlorophyll were also investigated based on water samples collected with Niskin bottle. The chlorophyll concentrations measured in these samples with the LIDAR displayed vertical distribution of chlorophyll with high concentrations in the well-mixed upper 20-m stratum and low ones in the anoxic hypolimnion. The specific temporal variations of fluorescence spectra for collected algae samples were recorded automatically with LIDAR in an onboard container. Perspectives of a compact fluorescent LIDAR for express remote sensing of algal abundance from various carriers (boats, drones) are discussed.
