Title:
Sound velocity data for the CORE-VTRCC cruise (2021)
Abstract:
This data set consists of sound velocity data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. To estimate sound velocity profiles for bathymetric processing, temperature profiles were first obtained for the water column throughout the survey every 50 nautical miles, for a total of 31 profiles. For that we used Expendable Bathythermograph (XBT) Lockheed Martin model T5 for the deeper portion of the survey (down to 1860 m water depth) and the model T7 over the shallower regions (down to 760 m). A salinity profile was then calculated by linearly interpolating the measured temperature profile to the nearest WOA/RTOFS salinity profile. Sound speed values were then calculated from the salinity updated profile using the UNESCO equation. The data file is in ASCII format. Funding for this work was provided through FAPESP awards 2016/24946-9 and 2020/08847-6, and through the Brazilian Navy program PROAMAZONIA AZUL.
