Coverage:
Latitude: -19.798460 * Longitude: 150.479620
Date/Time Start: 2010-03-11T01:45:00 * Date/Time End: 2010-03-11T01:45:00
Minimum DEPTH, sediment/rock: -10.80 m * Maximum DEPTH, sediment/rock: 18.51 m
Event(s):
325-M0046A (HYD_02ASite8) * Latitude: -19.798460 * Longitude: 150.479620 * Date/Time: 2010-03-11T01:45:00 * Elevation Start: -120.4 m * Elevation End: -117.5 m * Penetration: 32.2 m * Recovery: 2.78 m * Location: Great Barrier Reef, Australia * Campaign: Exp325 (Great Barrier Reef Environmental Changes) * Basis: Greatship Maya * Method/Device: Drilling/drill rig (DRILL) * Comment: Drilling Depth Methods: DSF: tag sea floor; CSF: let overlap if long; CCSF: let overlap if long. Depth correction made because of drill pipe “skipping” down a pinnacle side for 10.8 m before finally penetrating the seafloor; applying the same correction gives 117.5 m instead of the previously expected 106.7 m. Elevation Start = drill string tagging seabed including predicted tidal variations, Elevation End = corrected EM300 echo sounder data.
