Map of seismic research site on seafloor off Puerto Rico

Detailed Description

Locations of multichannel seismic reflection profiles (in black), collected during cruise FA2020-14. The profiles are overlain on colored and shaded multibeam bathymetry, Lidar topography (green and white) and near-shore bathymetry (darker blue), and NOAA coastal relief model (light blue and white).
