Field Experience:

Between 1966 and 1996, spent 45 months at sea on research vessels VEMA, CONRAD, ELTANIN, MELVILLE, MT. MITCHELL, KELEZ, ALVIN-LULU/AII, ATLANTIS II/ALVIN, JOHNSON, SURVEYOR, DISCOVERER, LANEY CHOUEST, SONNE, WECOMA, SONNE,and YOKOSUKA.
Have served as Chief Scientist or Co-Chief Scientist on thirty-seven expeditions, including eight submersible and five ROV campaigns.

Participated in ALVIN-LULU/AII expeditions in 1977 and 1978 off the East Coast of the U.S., in 1980, 1981, and 1985 on the Cocos-Nazca plate boundary, in 1984, 1987 and 1988, 1990 and 1991, 1993, and 1994 on the Juan de Fuca Ridge, Northeast Pacific. Observer on fifty-nine ALVIN dives and more than twenty dives on other submersibles.

Recent Professional Activities:
