CD-ROM
Leg 157 Materials
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 157. This CD also contains expanded versions of tables from Chapters 4, 5, 6, 7, 8, 9, and 10. CD-ROM production was conducted by the Borehole Research Group at Lamont-Doherty Earth Observatory, the wireline logging operator for ODP.
