Synergistic approach to measuring lake properties using satellite and in-situ remote sensing
Radar and electro-optical remote sensing data have been combined with in situ measurements of lakes on the North Slope of Alaska to obtain a baseline characterization of these lakes, determine change detection, document salt water intrusion, and investigate yellow billed loon habitat preference. This multi-faceted program, which also has applicability to the Great Lakes basin, has been aimed at using cost-effect technologies to investigate the remote lakes. In-situ data collected includes measurements using our autonomous water quality and bathymetry mapping robot instruments. ALWAS and BathyBoat robotic data have been used to provide baseline data as well as control and algorithm validation points for satellite remote sensing applications. Specifically, water depths from ALWAS and BathyBoat have been used in electro-optical and radar based water depth algorithms to produce bathymetry and volume of lakes on the North Slope. Additionally, in-situ data from the ALWAS buoys have been used to tune and validate satellite methods to then extend estimates of turbidity, chlorophyll, and salinity (expressed in alterations of aquatic vegetation and shoreline communities) to lakes that have not been directly sampled. These observations can then be linked to trophic index, saltwater intrusion, vegetation, and habitat.
