1986 Participant in the CASM VI cruise to the northern and southern segments of the Southern Explorer Ridge and Tuzo Wilson Seamounts. Took part in operations as on CASM V. Sulfide deposits were dredged from the southern segment of the Explorer Ridge, and hydrothermal plumes were located on the northern segment.
1985 Participant in the CASM V cruise to the Southern Explorer Ridge and Tuzo Wilson Seamounts: bottom photography, basalt dredging, nephelometer runs, sediment coring, and hydrocast deployment to obtain smoke samples from the hydrothermal vents. At least 10 new sulfide deposits were discovered. Also: co-leader of field trip to examine Precambrian stratigraphy and iron-formations north of Lake Superior.
1984 Participant in the CASM IV cruise and PISCES submersible dives to the Southern Explorer Ridge in the northeast Pacific (in Canadian territorial waters). Seventeen new massive sulfide deposits were discovered and sampled; near-axial sediments were recovered by gravity coring.
