Tahi Moana 7

video camera tow following up the water column anomaly identified on the NEL5a survey line, defined an approximately 150 m long traverse containing features interpreted as sulphide outcrops, and other indicators associated with hydrothermal activity, Chief Sci R. Arculus; Crowhurst et al. (2009): "Sulfides were recovered from ... a new discovery on the NE Lau spreading centre (NELSC), ~14 km north of the commercial discovery by Teck and ~7km north of the eruption site discovery during a RV Thompson NOAA survey, both during 2008."; Merle et al. (2008): tow NELSC, t08c11; Baker et al. 2019: site 3 with spreading rate 38 mm/year in Table 1; SRK report (2011): "One camera tow was conducted over Tahi Moana 7 which delineated a several hundred metre extent of chimney field. Also viewed were biota, alteration indicators and pillow basalts. A dredge of the seafloor recovered basalts and massive sulphides.";
