Gamma ray attenuation density and P-wave velocity of pressure cores from the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

This dataset includes gamma ray attenuation density and P-wave velocity measurements of pressure cores from the Pressure Core Analysis and Transfer System (PCATS). See Expedition UT-GOM2-2 Methods: Pressure Core Logging and Imaging (Flemings et al., 2025a, https://doi.org/10.5281/zenodo.13971228). The attached readme file, previewed below, describes the data file in this dataset and its contents. The readme file also contains links to where the data is presented in the expedition proceedings. Additional data you might expect to find in this dataset can instead be found at the following locations: The sample depths can be found in the curation dataset (http://doi.org/10.5281/zenodo.14926309). Download the file UT-GOM2-2 CORE LOG depths – sortable.xlsx. See tab “Core log”, Core type “FB” for the Pressure Coring Tool with Ball valve (PCTB) in the face bit configuration (PCTB-FB), and “CS” for the PCTB in the cutting shoe configuration (PCTB-CS) AND Core Process “PC” for pressure core processing. A summary of all logging and imaging for each core and section type can be found in the core images dataset http://doi.org/10.5281/zenodo.14261688. X-ray and CT images of pressure core, and X-ray and CT of whole round quantitatively degassed sections can also be found in the core images dataset http://doi.org/10.5281/zenodo.14261688. Quantitatively degassed sections were measured manually for whole round magnetic susceptibility and then imaged and logged for point magnetic susceptibility and X-ray fluorescence after splitting. Magnetic susceptibility for quantitatively degassed sections can be found in the conventionalized pressure core logs (http://doi.org/10.5281/zenodo.14518437). Split core logging of quantitatively degassed sections can be found in the split core logging dataset http://doi.org/10.5281/zenodo.14277995 and visible images for split quantitatively degassed sections can be found in the core images dataset http://doi.org/10.5281/zenodo.14261688. Processed conventionalized pressure core whole core logging data can also be found in Appendix E, of Expedition UT-GOM2-2 Site H (Flemings et al., 2025b, https://doi.org/10.5281/zenodo.13971276).
