Notes on Vent Field Description:
on Ghizo Ridge, which is putative extinct spreading segment; this location does not correspond with an OSR (oceanic spreading ridge) segment in Bird (2003); re-classified to arc volcano based on Chadwick et al. (2009): "Although Simbo and Ghizo Ridges are part of the Woodlark Basin in a geographic and tectonic sense, very few of the samples recovered there have N-MORB chemical and petrographic characteristics, and most reveal a strong influence of an arc component."
Notes Relevant to Biology:
although 2000 cruise FR04/00 report (http://www.marine.csiro.au/nationalfacility/franklin/plans/2001/fr04_00s.html) says "a site on the western flank in an area described by the [Metal Mining Agency Japan]/SOPAC cruise as a hydrothermal vent community" - the SOPAC report online (http://www.sopac.org/data/virlib/TR/TR0209.pdf) does not mention hydrothermal vent community
Year and How Discovered (if active, visual confirmation is listed first):
1993 observations did not confirm activity
