Core curation and sampling logs from the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

This dataset contains the coring log for Hole H002 (core depths, drill ahead depths), the coring log for Hole H003, the final core log (core depths all cores), the cut sections and pieces of the cores, and the locations of discrete samples and measurements from the cores. Depths presented include archived and compressed depths for all conventional and pressure cores. The archived depth scale includes expansion due to gas voids and allows for overlaps between successive cores. The compressed depth scale uses linearly compresses the depths in each expanded core to fit within the length of the coring advance. All depths are calculated as the measured depth below seafloor and are not corrected for deviation of the borehole.
