Abstract:
The laser remote sensing (lidar) techniques are applied in a variety of environmental studies. It fills the gap between the satellite remote sensing and ground sampling. One of the principal merits of laser sensing is the possibility to obtain extensive information with high resolution from large water surfaces in real time. Fluorescence LIDAR is a useful tool in water pollution monitoring, based on fluorescence signature of each contaminant. The paper presents a comparative analysis of river and seawater quality in the aim to emphasize the organic pollution under the influence of the human activities.
Laser induced fluorescence measurements were performed using a Fluorescence LIDAR during the cruise on Danube Delta and on the Black Sea Romanian cost. The characteristics of the spectral fluorescence signatures of water (intensity, shape, bands) were analysed in connection with the extraction area and pollutants type.
