Notes on Vent Field Description: 
2015 MESH Expedition website, accessed 13 May 2015, "At Havre we’ve found several hydrothermal vents. We identify them by measuring temperature with a heat probe and observing temperature gradients that exceed the geothermal gradient. The presence of vents shows that there is still excess heat underground - possibly from cooling magma that was not erupted in 2012. ... Bacterial mats flourish around the vents we see at Havre."; NZAPLUME II cruise; located in New Zealand's Kermadec Benthic Protection Area,, accessed 13 May 2015
Year and How Discovered (if active, visual confirmation is listed first): 
2015 ROV Jason II; 2002 plume only
