Notes on Vent Field Description:
volcanic island in rifted fore-arc; Pichler and Humphrey (2001): "Focused, vigorous discharge of gas from vent orifices, 20-50 cm in diameter, was observed at six locations. A possible discharge of clear liquid associated with the gases is inferred from observations of shimmering above vent orifices. ... Temperatures at the point of discharge range from 60 to 96 C. Sites of gas exhalation are marked by small funnel-shaped indentations (i.e., conical depressions) in the sandy bottom. ... Two types of hydrothermal precipitates are predominant around the submarine vents: (1) Fe-sulfides... and (2) dolomite"
