These data are used in Rovere et al., 2017 (PNAS, see references).</p> <p><strong>Bathymetry: </strong>data was acquired with an&nbsp;MX Biosonics Aquatic Habitat Echosounder (Depth accuracy 1.7cm&plusmn;0.2% of depth; DGPS positional accuracy: &lt;3m, 95%) mounted on a small boat. No tidal correction has been applied. No IMU corrections to take into account wave motion were applied.</p> <p><strong>GPS: </strong>GPS&nbsp;points and lines were measured with a Trimble Pro XRT GPS receiving real-time Omnistar HP corrections (2-sigma 95% accuracy of 10cm).
