Notes on Vent Field Description: 
2015 MESH Expedition website, accessed 13 May 2015, http://web.whoi.edu/mesh/379/: "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, http://www.fish.govt.nz/en-nz/Environmental/Seabed+Protection+and+Research/Benthic+Protection+Areas.htm, accessed 13 May 2015
