Mission Plan
Two ships will be involved in this expedition, the University of
Washington's R/V Thomas G. Thompson and the Canadian Coast Guard's John P.
Tully. The Thompson will use the remotely operated vehicle, ROPOS, to study and
prepare the chimneys for extraction, while the Tully will do the actual
lifting. The following cruise schedule is tentative.
June 22-25
Load Thompson at Seattle, Washington
Load ROPOS & winch system
Mount Applied Physics Lab (APL) chainsaw on ROPOS
Load APL recovery line baskets & recovery frames
June 26
Thompson set sail
June 27
Thompson install & survey transponder net
June 28
Thompson:
ROPOS survey targeted black smoker field & chimneys
Scientific activities: test strength of chimneys & measure temperatures
Test saw on chimney?
