| Abstract | Cruise SO 167 visited the south Tonga volcanic arc, Valu Fa Ridge, South Fiji Basin, Osbourn Trough and Louisville Ridge. Key objectives of this program were to provide the first "ground truth" concerning the south Tonga arc, to locate the geochemical signature of the subducting Louisville Ridge within the arc, to examine the relationship between tectonic, magmatic and hydrothermal processes on Valu Fa Ridge, document any changes in hydrothermal venting at the Vai Lili and Hine Hina sites and establish the origin and age of the Osbourn trough. Tough multibeam data has been recorded to map the different volcanoes, it was not the focus of the cruise and the responsible party has provided no further acquisition information. |
