SATELLITE BATHYMETRY USE IN NUMERICAL MODELS OF OCEAN THERMAL STRESS

SATELLITE BATHYMETRY USE IN NUMERICAL MODELS OF OCEAN THERMAL STRESS

Techniques for deriving estimated bathymetry from satellite data are well established; however, use of this product in complex terrains is limited. Accurate bathymetry is essential in the construction of hydrodynamic models and satellite-derived bathymetry is a strong candidate for use in coastal an...
