Notes on Vent Field Description: 
cone within Macauley Caldera, venting at summit, also has flank vent fields 200-400 m below the summit; Wright et al. (2006): "A 700-m wide and 300-m high post-caldera cone coalesces with the inner eastern caldera wall, sited within 1.5 km of the island shoreline."; de Ronde et al. (2007): "submersible dives during April 2005 at Macauley cone (see http://oceanexplorer.noaa.gov/explorations/05fire/) showed this site was precipitating large amounts of elemental sulfur"; 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
