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]
