December 2004
The CPE coastal geology team collected sand samples from Bay County DNR
monuments T-5 to R-60. According to protocols, surface samples were collected
along the mean tide line, on the mid-berm slope, and at the berm crest.
Additionally, a sample was obtained at a 3-ft depth below the mid-berm
surface.

The tug and barge docked at City Marina dock, Panama City, during the night.
The drilling barge departed the dock at 6:30am. Due to sea conditions (waves
were 3 to 5 ft high), no coring was conducted on the offshore borrow areas.
A core was collected within St Andrews Pass, but during recovery, a leg on
the coring unit was twisted and damaged. This twisting was caused by the
strong in coming tide. The barge returned to the dock to repair the coring
frame.

The drilling barge left the dock at 6:30am. Due to the sea conditions (waves
were 4 to 6 ft high), no coring was conducted on the offshore borrow areas.
Three cores were collected in St Andrews Pass and one core was taken just
outside the jetties. Due to sea conditions (wave 3-5 ft high; winds: 15-20
kts) one core was taken outside the jetties but no more cores were attempted
outside the jetties.
