Sampling rate
GSC / Dalhousie instruments		139.00 Hz

Instruments
GSC = Geological Survey of Canada (Atlantic Division)	three-component 4.5-Hz geophones + hydrophone
DAL = Dalhousie University (Dept. of Oceanography)		three-component 4.5-Hz geophones + hydrophone

Clock drift
+ sign	OBS clock is ahead of GPS clock
- sign	OBS clock is behind GPS clock
1) There is an additional static shift of +2 ms for all instruments
2) Instrument probably had clock jump. Time check indicated a drift of -3580 ticks = -28.640 s. No clock drift applied to SEGY data other then static shift
