Detailed Description

Preliminary seafloor bathymetry (shown in colors) collected by the USGS research vessel Parke Snavely on July 11, 2017. Relative depths shown in color, superimposed on a shaded-relief map from the June 26 USGS air-photo survey. Note white data gap next to the shore where water was too shallow for the Snavely to map. Shawn Harrison hopes to fill this gap with data derived from drone videos
