Notes on Vent Field Description:
Nautilus Minerals calls this Tahi Moana 5; SRK Consulting report for Nautilus Minerals (http://www.nautilusminerals.com/i/pdf/2008NautilusExplorationNI43-101Report.pdf): "Seven small fields of chimneys are named Tahi Moana 5a through to Tahi Moana 5g; the largest of which is approximately 230 by 50m in area. Chimney fields with columns up to 15m high are found in Tahi Moana 5a, 5b, 5c and 5d. Many of the chimneys are active although the biota is generally sparse."; cruise SS02/2003 summary (http://www.marine.csiro.au/nationalfacility/voyagedocs/2003/0203s.htm): "we discovered new strong plumes (nephelometry, thermal, and Eh) centred about the northern end of the Hine Hina section"
