Understanding satellite-derived bathymetry using Sentinel 2 imagery and spatial prediction models

GIScience & Remote Sensing, 2020
Optical satellite data is an efficient and complementary method to hydrographic surveys for deriving bathymetry in shallow coastal waters. Empirical approaches (in particular, the models of Stumpf and Lyzenga) provide a practical methodology to derive ...

Swath sonar multibeam bathymetry during HEINCKE cruise HE450 with links to raw data files of bathymetry and water column information

, 2016
The aim of the cruise was to explore gas emissions using the echosounders of the ship along the slope of the Barents Sea up to Svalbard to find more evidence for dynamic changes of gas hydrates and emissions of free gas.
