DGPS and Echosounder data for Glass Window Bridge, Eleuthera, Bahamas.

Bathymetric and Differential GPS data collected on Eleuthera, Bahamas as collected by survey instruments. These data are used in Rovere et al., 2017 (PNAS, see references). Bathymetry: data was acquired with an MX Biosonics Aquatic Habitat Echosounder (Depth accuracy 1.7cm±0.2% of depth; DGPS positional accuracy: <3m, 95%) mounted on a small boat. No tidal correction has been applied. No IMU corrections to take into account wave motion were applied. GPS: GPS points and lines were measured with a Trimble Pro XRT GPS receiving real-time Omnistar HP corrections (2-sigma 95% accuracy of 10cm). Heights are referred to the ITRF Ellipsoid. All data is in .shp format.
