equipped with a slip-type catcher. (As it turned out later, this maneuver was unsuccessful.) The barrel became stuck in the BHA, effectively blocking the base of the pipe and preventing any further out-of-the-pipe logging efforts. By noon on 17 February, a plug of cement approximately 24 m thick had been slurried into Hole 627B from 536 to 512 m sub-bottom in order to isolate the radioactive source in the log ging tool. The cementing process took place with the drill bit at 467 m sub-bottom. Attempts to log in the pipe down to that depth were unsuccessful as a result of further equipment mal functions, so at 1600 hr the decision was made to abandon Hole 627B completely. The drill bit was pulled to a depth of 63 m sub-bottom by 1700 hr, and 50 bbl of mud was pumped into the hole. All pipe was back on deck by 1930 hr, when it was deter mined that the logging tool was lost and therefore presumed ce mented in the bottom of Hole 627B. The JOIDES Resolution was under way for BAH-8-A, approximately 6 n. mi up the slope of Little Bahama Bank along seismic line LBB-18 (Fig. 3), by approximately 2030 hr, 17 February.
