Abstract

1. Important environmental problems of coastal and lagoon areas have stimulated interest in scientific research. Innovative technologies can provide good tools for observing phenomena and measuring parameters.

2. The short overviews given in this article refer to the results obtained using active remote sensors and passive remote sensors in practical applications to support monitoring and research activities.

3. Active sensors such as FLIDAR-3 (Fluorescence Light Detection and Ranging) (optical), tomography (acoustical), and CODAR (Coastal Ocean Dynamics Applications Radar) (radio) emit their own electromagnetic energy to the investigated surface and sense the reflected energy from the surface; while the passive sensors, such as MIVIS (Multispectral Infrared and Visible Imaging Radiometer), NOAA (National Oceanographic and Atmospheric Agency)/AVHRR (Advanced Very High Resolution Radiometer) and Landsat/TM, do not emit energy but measure energy reflected/emitted to the sensor from the investigated surface.
