Notes on Vent Field Description: 
depth approximate; approx. position from Fig.3, targets generated by cruise SS02/2009 (http://www.marine.csiro.au/nationalfacility/voyagedocs/2009/MNF-SS2-09_sum.pdf): "CTD tow line CL2_TY_1 along a parallel ridge to the CLSC. Two excellent plumes were found on this tow. Both are coincident strong NTU and Eh responses. The first (CL_7) is on the south flank of an elongated mound where there is a distinct flattening of slope. The second plume (CL_8) occurs about 10km to the north."; dredge did not recover sulfides
Notes Relevant to Biology: 
Year and How Discovered (if active, visual confirmation is listed first): 
2009 plume only
