Notes on Vent Field Description:
Coastal Papua New Guinea; Studt (1961): "The most striking hydrothermal feature is the complete absence of hot springs more than a foot or two above sea level. The springs occur typically along the shoreline between high- and low-water levels, ...there are many parts of the Matupi-Rapindik shore-line where bubbling and upwelling of hot water can be seen"; Ferguson & Lambert (1972) sampled sediments and fluids
Notes Relevant to Biology:
see Tarasov et al. (1999)
Year and How Discovered (if active, visual confirmation is listed first):
