Notes on Vent Field Description:
approx. position from Fig.2, targets generated by cruise SS02/2009 (http://www.marine.csiro.au/nationalfacility/voyagedocs/2009/MNF-SS2-09_sum.pdf): "Data review suggests source is possibly the western flank of ridge just to the SE. This is the only feature that appears to be at the right level. The top of the ridge is at 2140m depth. The eastern plume near the south end of ELSC3_TY_1 could either be coming from the nearby volcanic cone or possibly a NS ridge to the north"
Notes Relevant to Biology:
Year and How Discovered (if active, visual confirmation is listed first):
