Notes on Vent Field Description:
note: Nautilus Minerals had camera tow and FRSC02 sampled in 2009 Chief Sci R. Arculus (http://www.nautilusminerals.com/s/Media-NewsReleases.asp?ReportID=352245&_Title=Nautilus-Confirms-High-Grades-in-Phase-One-of-2009-Tongan-Exploration), (http://www.marketwire.com/press-release/Nautilus-Minerals-Inc-TSX-NUS-995322.html); southern section of line NEL11a on cruise SS02/2009 (http://www.marine.csiro.au/nationalfacility/voyagedocs/2009/MNF-SS2-09_sum.pdf): "Upon post-processing of the NEL11a southern extent tow data, we resolved another target approximately 5km south of the site central venting area. This site lies on a small ridge line between NEL11a and NEL11b and was identified by significant Eh response on the two lines."; located between Stations RC133 and RC132 reported by German et al. (2006)
