Macheriotou, Lara; Bezerra, Tania N; Pape, Ellen; Vlaeminck, Bruno; Vanreusel, Ann: Grain size distribution measured on MUC and PUC samples during SONNE cruise SO295 to the BGR and GSR license areas in the Clarion Clipperton Fracture Zone [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.982349 (dataset in review)
Abstract:
This dataset contains sedimentary parameter grain size distribution measured from Multicorer (MUC) and Pushcore (PUC) samples from the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR, Germany) and Global Sea Mineral Resources (GSR, Belgium) license areas in the Clarion Clipperton Fracture Zone (CCFZ) collected on onboard the RV SONNE295 cruise in 2022. Grain size analysis was completed using laser diffraction (Malvern Mastersizer Hydro 2000 G). These data were collected to characterize the sediment in the CCFZ and to correlate these values to observed levels of biodiversity. Values are given in their respective units (SI) and have been collected and measured by the Marine Biology Research Group of Ghent University (Belgium).
