Notes: Potential seawater contamination and microsphere counts are from sediment samples and parallel slurries. The delivery of microspheres was confirmed by detecting microspheres in scrapings and water samples from the outer core liner (right column). Fov = field of view. ND = not determined. BD = below detection. * = slurry and sediment samples are from different core sections. † = single, nonreproducible bead observation, may represent handling contamination. ‡ = the samples are from a wet portion (~58-65 cm) and a dry portion (140-145 cm) of Section 201-1230A-38X-1. BD = below detection, ND = none detected.
