Borehole Seismic Data


ODP logging contractor: LDEO-BRG

Hole: 948D

Leg: 156

Location: N Barbados Ridge (tropical NW Atlantic)

Latitude: 15° 31.464' N

Longitude: 58° 43.907' W

Logging date: June, 1994

Bottom felt: 4949.5 mbrf (used for depth shift to sea floor)

Total penetration: 538 mbsf

Total core recovered: none.


TOOL USED: ASI (Array Seismic Imager).


The logging data was recorded by Schlumberger in DLIS format. All processing, including first arrival picking and stacking, was performed by Schlumberger during Leg 156. 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).
