Notes on Vent Field Description:
sample obtained at seamount immediately north of Awu Volcano; McConachy et al. (2001): "appears relatively young and may be parasitic to Awu volcano. It has a summit crater or small caldera, about 800 m across and breached to the northwest. A dredge hauled within the caldera returned numerous un-abraded fragments of fresh pumiceous dacite glass with prominent phenocrysts of plagioclase, orthopyroxene and clinopyroxene, plus small angular fragments of a similar but less vesicular lithology. Coatings of soft ferruginous deposit on some fragments suggest that the caldera is hydrothermally active"; 2010 EX1004 cruise, ROV Dive ROV05, http://oer.hpc.msstate.edu/okeanos/ex1004l2/ex1004L2-DIVE05-SUMMARY-FINAL.pdf, accessed 1 June 2015: "CTD casts the previous night indicated hydrothermal activity", "ROV found no evidence of hydrothermal activity"
