Abstract:

After finding an error in the composite section for ODP Site 145-882, we reconstructed a new composite (continuous sediment section) using Hole 145-882A and Hole 145-882B. Equivalent sediment features in cores from each hole are aligned by changing the depth of cores from each hole by an offset added to the original CSF depth. This dataset displays the offsets in meters for each core to align them with each other.
