Photographs of Vitoria Trindade Ridge sediment samples from the CORE-VTRCC cruise (2021)

This data set presents photographs of sediment samples collected in 2021 over the Vitoria Trindade Ridge during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. During the sampling program, nine seafloor sediment samples were collected within the Vitória-Trindade Ridge with a Van-Veen grab sampler (3600 cm²) on the top of the volcanic seamounts. Sample V7 collected only rhodoliths, without additional sediments. Samples were washed, dried, weighed, sieved, and analysed. Microscopic photographs were taken with a Zeiss Stemi DV4 stereomicroscope, at zoom scale of 8x and a total diameter of 26 mm. The photographs are in JPEG image format. For the analysis, each seafloor sample was subdivided into ten subsamples (Q number). Codes: V# - Number of Sample (_# goes when there is multiple images for the same sample); Q# - Number of the quartile sample (only for the biofacies). Funding for this work was provided through FAPESP awards 2016/24946-9 and 2020/08847-6, and through the Brazilian Navy program PROAMAZONIA AZUL.
