CORE-VTRCC Cruise Report: Geophysical Acquisition and Seafloor Sampling along the Vitória-Trindade Ridge.

This work reports the data obtained by the multidisciplinary cruise CORE-VTRCC surveying on the region around the Vitória-Trindade Ridge (VTR) aboard the vessel NHo Cruzeiro do Sul (October 18 to November 6, 2021). The main objectives of the VTRCC Cruise were (1) to assess the role of the VTR as an oceanographic barrier for bottom currents along the Brazilian margin; and (2) to characterize the morphology of the volcanic seamounts and its relationships with the carbonate sediments that cover it. For that, we performed multibeam bathymetry, magnetometry, high-resolution multichannel seismic survey, subbottom profiling survey, and seafloor sampling along the VTR and along the Columbia Deepwater Channel.
