Radiocarbon datings of mollusk shells, sedimentation rates and accumulation rates of sediment matter in core PS2718-6

A bottom sediment core about 8 m long sampled in the eastern Kara Sea near the entrance to the Vil'kitsky Strait was studied. An age model was constructed based on four 14C datings obtained from by thy accelerating mass spectrometry method. Results of grain size, chemical, mineralogical, and foraminiferal analyses were adjusted to the model. A paleoceanological interpretation of these data together with paleoclimatic data on the Bol'shevik Island located in the neighborhood was performed.

(Table 1) Summary of acoustic properties at DSDP Holes 60-453 and 60-459B

Laboratory measurements of physical properties are important because the results may be applied to the interpretation of seismic and other types of geophysical data, and because they can be used to estimate the in situ physical properties of different lithologies present beneath the sea floor. In this chapter, wet-bulk densities and compressional-wave velocities, measured at elevated confining pressures, are reported for a suite of seven sediment samples recovered on DSDP Leg 60. Of the seven samples studied, two are mudstones, two are vitric tuffs, and three are chalks. All but one of the samples are from Hole 459B, near the eastern limit of the Mariana fore-arc region. In five cases, velocities were measured parallel and perpendicular to bedding to test for velocity anisotropy.
