Increasing the Existence of Very Shallow-water LIDAR Measurements Using the Red-channel Waveforms

open access: yes, 2007
Mapping shallow-water bathymetry with acoustic techniques is complicated and expensive. The environmental parameters in shallow-water (\u3c2 m) areas become more variable and greatly impact the depth extraction from the survey measurements.

Atmospheric Correction of Aisa Measurements Over the Florida Keys Optically Shallow Waters: Challenges in Radiometric Calibration and Aerosol Selection

open access: yes, 2015
An Airborne Imaging Spectrometer for Applications (AISA) hyperspectral imager was deployed on a manned aircraft flown at 1305-m altitude to collect data over optically shallow waters in the Florida Keys with the ultimate goal of mapping water quality and

Mapping Bottom Depth and Albedo in Coastal Waters of the South China Sea Islands and Reefs Using Landsat TM and ETM+ Data

open access: yes, 2014
Optical models for the retrieval of shallow water bottom depth and albedo using multispectral data usually require in situ water depth data to tune the model parameters.
