Notes on Vent Field Description:
Email from C. Devey, Jan. 2010: "we found ... a plume (but did not see the vents on the seafloor) centred around 9°48´S/155°04´E (so on Segment 3B)"; cruise report: "Near the eastern end of segment 3 (segment 3B, station 137) a strong plume anomaly was detected by MAPR on the dredge wire. As a result two tow-yo studies were planned to map the plume. According to the available data a single TV grab deployment was chosen in attempt to find the source of the plume. No vent, but vent proximal indicators were found."
Notes Relevant to Biology:
Year and How Discovered (if active, visual confirmation is listed first):
2009 plume only
