Notes on Vent Field Description: 
position approximate from cruise SS02/2012: "caldera of the East Futuna Zone" (east of Futuna Spreading Center and not to be confused with Futuna Trough in New Hebrides back-arc); longitude is updated from Ver. 2.1 database; depth from specimen deposited into MNHM with record in GBIF accessed 10 June 2015,; Konn et al. (2011): "A new area off-shore the Futuna island was surveyed in fall 2010 during a French cruise conducted by Ifremer and two new hydrothermal active fields (Amanaki and Kulo Lasi) were discovered"; FUTUNA 2010 cruise likely confirmed venting:; Charlou et al. (2011): "The fluids exhibit temperatures of 343 C, pH of 2.36, low H2S content..."; cruise SS02/201: "hydrocast (NLTH-14) detected a large multilayered hydrothermal plume, with a major layer at ~1180m and subsidiary layer at 1280m. The former coincides with the deepest portion of the caldera rim"; Bird (2003) model does not represent this complex region well enough to provide good estimate of spreading rate
Year and How Discovered (if active, visual confirmation is listed first):
