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. : {"references": ["Rovere, A., Casella, E., Harris, D.L., Lorscheid, T., Nandasena, N.A., Dyer, B., Sandstrom, M.R., Stocchi, P., D'Andrea, W.J. and Raymo, M.E., 2017.
