History

The first evidence of the existence of Clark was found during 1988 GLORIA side-scan mapping. These interpretations were later confirmed via photography and oceanic dredging in early 1992 during the 3-week Rapuhia cruise.[1]

In 2006, during a New Zealand-American NOAA Vents Program expedition, sulfide chimneys and diffuse hydrothermal venting were observed.[2]

There have been no known eruptions of Clark.[3]
