All geopetals are within 2° from horizontal as viewed on the archive-half core face, except at 29.6 mbsf, where the underlying 6 cm of sediment has clearly slumped. Because of >100% recovery in Core 330-U1374A-5R, the geopetals in Section 330-U1374A-5R-4 appear at greater depths below seafloor than those in Section 330-U1374A-6R-1.
