Core Images from the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

This dataset contains core images and links to core logging datasets for different core and sample types according to the provided Summary Table. Use the summary table to find the correct zip file by cross-referencing the core type with the image type you are trying to find. For example, to find the CT image of the pressure core H003-08CS from PCATS, cross-reference the column labeled "Pressure core (FB and CS)" with the row labeled "PCATS CT Slabs" to find the name of the zip file you want in the corresponding table cell, "CT-slabs_tif_PCTB_uncut_cores.zip". The attached readme file, previewed below under Files, describes all the data files in this dataset and their 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: Core and section-piece 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 tabs “Core log” and “Section-piece log”. The attached summary of logging and imaging file summarizes the sensor data and images obtained for each core and section type. Summary Table Summary table information: Row 1 and 9: Core types including Column C: conventional cores recovered using the Advanced Piston Corer (H) and the Extended Core Barrel (X); and Column D: pressure cores recovered with the Pressure Coring Tool with Ball Valve in the face bit configuration (FB) and the cutting shoe configuration (CS). Row 2 and 10: Core processes include Column C: conventional core processing; and Column D: Pressure core processing including storing pressure core at high pressure and low temperature (STORE), quantitatively degassing pressure core (QD), cryogenically freezing and depressurizing pressure core (CRYO), rapidly degassing pressure core (RD), and conventional core processing of pressure cores recovered at atmospheric pressure (failed pressure core). Row 3 and 11: Sample codes for sections of whole-round core include regular pore water sample (IWR), organic pore water sample (IWO), microbiology sample (MB), moisture and density (MDW), geomechanics (GEOM), archival half (A), working half (W), and bagged unconsolidated sediment (BAG). Row 4: Data and images collected using a Pressure Core Analysis and Transfer System (PCATS) on the Q4000 including images of failed pressure cores from Hole H002 repressurized with air. These repressurized cores were logged and imaged in PCATS before conventional core processing. Row 5: Data and imaging collected using a Multi-Sensor Core Logger (MSCL) infrared imaging (IR) used on the Q4000. Row 6: Data and imaging from a MSCL standard (S) core logging and X-Ray imaging at College Station. Row 7: Data and imaging from the MSCL split core (XZ) logging and imaging system in Salt Lake City. Row 8: Photos of split core working halves after sampling in Salt Lake City.
