Physical properties at Site 1214 were measured on both whole-round sections and discrete samples from split-core sections. Because of poor core recovery, only one core section was measured on the multisensor track (MST). The MST records of magnetic susceptibility and gamma ray attenuation (GRA) bulk density thus only represent the Pleistocene interval. Discrete measurements of compressional P-wave velocity were made at a routine frequency of at least one measurement per split-core section from Hole 1214A. No index properties measurements were made.
Whole-round Core 198-1214A-1R was measured on the MST for magnetic susceptibility and GRA bulk density at 3-cm intervals. No P-wave or natural gamma radiation measurements were made with the MST. The collected MST data are archived in the ODP Janus database.
Hole 1214A magnetic susceptibility values appear to display no discernible downhole trend, although these data are comparable with values measured in the Pleistocene interval at other Leg 198 sites (see "MST Measurements" in "Physical Properties" in the "Site 1207," "Site 1208," "Site 1209," "Site 1210," "Site 1211" and "Site 1212" chapters). GRA bulk density data show a slight downhole increase between the seafloor and ~1.25 mbsf.
Discrete measurements of compressional P-wave velocity were made on Site 1214 split-core sections using the modified Hamilton Frame (PWS3) velocimeter. These data are listed in Table T8 and illustrated in Figure F8. Data were collected at a routine sampling frequency of at least one measurement per section. A variety of lithologies were cored at Site 1214, each of which has distinct P-wave velocities (Table T9). Within the recovered sediments, a general downhole increase in P-wave velocity between 0 and ~220 mbsf is most likely related to progressive sediment lithification with increasing burial depth.
Physical properties data from Site 1214 primarily reflect compositional variability between the different sediments recovered. Data from the recovered sediments are diagnostic both of the depth of burial (i.e., degree of lithification) and also the amount of silicification. The high degree of variability of P-wave velocities below 90 mbsf, which is related to lithology, has significant implications for seismic interpretations of Site 1214 and related stratigraphic sections.
