Estimating chlorophyll a concentrations from remote-sensing reflectance in optically shallow waters
Remote Sensing of Environment, 2006A multi-spectral classification and quantification technique is developed for estimating chlorophyll a concentrations, Chl, in shallow oceanic waters where light reflected by the bottom can contribute significantly to the above-water remote-sensing reflectance spectra, Rrs(k). Classification criteria for determining bottom reflectance contributions for

Global Delineation of Optically Shallow and Optically Deep Water Using Machine Learning
IGARSS 2024 - 2024 IEEE International Geoscience and Remote Sensing SymposiumWe developed a Random Forest model to classify optically deep and optically shallow water pixels in Sentinel-2 imagery. The model was trained and tested on a global dataset of pixels visually interpreted from Sentinel-2 imagery.

Ocean color algorithms in optically shallow waters: limitations and improvements
SPIE Proceedings, 2005Current ocean color algorithms based on remote-sensing reflectance spectra, Rrs(λ), overestimate chlorophyll a concentrations, Chl, and particulate backscattering coefficients, bbp(λ), in optically shallow oceanic waters due to increased bottom reflectance.

Decorrelating remote sensing color bands from bathymetry in optically shallow waters
IEEE Transactions on Geoscience and Remote Sensing, 2006We have developed a simple technique to decorrelate remote sensing color band data from depth in optically shallow water. The method linearizes color band data with respect to depth by subtracting an optically deepwater value from the entire waveband under consideration and taking the natural logarithm of the result.

Airborne mapping of shallow water bathymetry in the optically complex waters of the Baltic Sea
Journal of Applied Remote Sensing, 2016Accurate determination of the water depth is important for marine spatial planning, producing maritime charts for navigation, seabed morphology studies, and carrying out different activities in the coastal waters. Bathymetric data are lacking foremost in the shallow water regions as those areas are often inaccessible to the hydrographic ships carrying ...
