WebBathymetry deals with the topography of the seafloor. The history of this branch of hydrography goes back more than 3,000 years, with the first evidence of water depth measurements in historical records from ancient Egypt ( Theberge, 1989 ). The first measuring devices were sounding poles and lines with weights attached to them. WebThis data set is a fusion of land topography with measured and estimated seafloor topography. It is largely based on version 11 of SRTM30+ (Becker et al, 2009; Sandwell et al, 2014), augmented with the gridded bathymetric data sets developed by the four Seabed 2030 Regional Centers.
