Notes on Vent Field Description:
southernmost segment, Northeast Lau Spreading Center (NELSC); Maka was discovered in 2008 commercial ROV funded by Teck/Nautilus Minerals; SRK Consulting report for Nautilus Minerals (http://www.nautilusminerals.com/i/pdf/2008NautilusExplorationNI43-101Report.pdf): "The Maka chimney field is on the crest of the NE Lau Spreading Centre and consists of numerous black smokers."; Puipui eruption site (between Maka and Tafu) was observed in 2009 ROV Jason II Dive 416, after eruption plume detected in 2008; Maka is southern summit at 1560 m; Tafu is the shallower, northern summit on this segment; German et al. (2006): Stations RC 142–145 plume site; Merle et al. (2008): vertical cast NELSC, v08c07; Global Volcanism Program groups Tafu, Puipui, and Maka all together as one volcano "Tafu-Maka" 243120
Notes Relevant to Biology:
(http://laueruptions.blogspot.com/2009/05/biological-preview.html): "exploration of the Northeastern Lau Spreading Center (NELSC) has yielded two active vent fields that host foot long tubeworms, mussels, crabs, several species of small snails and shrimp, as well as vent-endemic fish"
Year and How Discovered (if active, visual confirmation is listed first):
2008 commercial ROV; 2004 plume only; 2006 plume and chimney samples
