Borehole Seismic Data
ODP logging contractor: LDEO-BRG
Location: Demerara Rise (equatorial NW Atlantic)
Latitude: 9° 27.230' N
Longitude: 54° 20.518' W
Logging date: January 18-19, 2003
Bottom felt: 2962 mbrf (used for depth shift to sea floor)
Total penetration: 284.7 mbsf
Total core recovered: 216.05 m (75.89%)
TOOL USED: WST (Well Seismic Tool)
The logging data was recorded by Schlumberger in DLIS format. All processing, including first arrival picking and stacking, was performed by Schlumberger during Leg 207. The data was then converted into SEGY format at the Borehole Research Group of the Lamont-Doherty Earth Observatory, using the SEGY Save module in GeoFrame.
Stacks are generally calculated with at least seven good traces.
All the data in the SEGY files are sorted shot by shot (i.e. chronologically).
