CD-ROM
The CD-ROM in the back of this volume contains depth-shifted and processed logging data provided by the Borehole Research Group at Lamont- Doherty Earth Observatory, as well as shipboard gamma-ray attenuation porosity evaluation (GRAPE), index property, magnetic susceptibility, and natural gamma, P-wave, and reflectance data of cores collected on board JOIDES Resolution during Leg 160. This CD also contains expanded versions of some tables. CD-ROM production was conducted by the Borehole Research Group at Lamont-Doherty Earth Observatory, the wireline logging operator for ODP.
