ODP logging contractor: LDEO-BRG Hole: 1251H Leg: 204 Location: Hydrate Ridge - Cascadia Margin (NE Pacific) Latitude: 44° 34.2089' N Longitude: 125° 4.4514' W Logging date: August 17-18, 2002 Bottom felt: 1220 mbrf Total penetration: 445 mbsf Total core recovered: no cores taken in this hole. VSP TOOL USED: WST3 (3-Component Well Seismic Tool) Acquisition Break Time: Time between start of recording and first break Acquisition Transit Time: Time between shot firing (as recorded by blast phone) and first break. The shot is fired ~12 milliseconds after start of recording. The difference between Acquisition Break Time and Acquisition Transit Time is not constant and varies for each shot.
