A submersible dive conducted on Volcano #1 located near 21 degrees 09'S-175 degrees 45'W on the Tonga Arc showed that the volcanic edifice with a caldera floor area of 30 km(2) located at and 450 m deep (b.s.l.=below sea level) was constructed recent

New multibeam mapping and whole-rock geochemistry establish the first order definition of the modem submarine Kermadec arc between 30 degrees and 35 degrees S. Twenty-two volcanoes with basal diameters > 5 km are newly discovered or fully-mapped for

Hydrothermal gases from shallow seafloor vents in the Bay of Plenty, New Zealand contain CO2, CH4, and the higher gaseous hydrocarbons up to i-, n-C4H10. The gases are similar to those discharged at fumaroles on the nearby White Island. Carbon isotop

The well-studied Galapagos Archipelago is a small part of the much larger Galapagos Volcanic Province (GVP) consisting of the Cocos, Carnegie, Coiba and Malpelo aseismic ridges and related seamount provinces. Although these aseismic ridges and seamou

Submarine hydrothermal vents and associated seafloor mineralization on the Tonga arc have been found for the first time, in the summit calderas of two shallow-water volcanoes, greatly extending the known areas and diversity of seafloor hydrothermal a
