Data acquired during the CORE-VTRCC Cruise. (a) Multibeam bathymetry survey occurred throughout the vessel track with the exception of shallow depths (<100 m). Seafloor samples were acquired atop the Columbia Seamount (V01 and V02), atop the Dogaressa Bank (V03 and V04), atop the Davis Bank (V05 and V06) and atop the Jaseur Seamount. (b) Sub-bottom and sound velocity profiles were also acquired throughout the cruise track but not at <100 m depths. (c) Multichannel Sparker Seismic data was acquired along the Columbia Channel (L01-L03), along the VTR (L07-L15) and at the Rio de Janeiro continental slope (L17). (d) Marine magnetometry was acquired throughout the survey track when sea conditions were safe.
