The SW Pacific is an area of active plate collision renowned for its seismicity and hydrothermal processes. The Hikurangi-Kermadec margin and bark-arc have been studied for hot vent mineralisation; they have also recently become the focus of detailed first-time studies of cold methane seepage off the east coast of New Zealand. The existence of hydrothermalism and cold seepage in close proximity with fossil exposures on land makes this a unique area for studying the link between hot and cold fluid flow and its long-term history by integrating marine and related terrestrial disciplines.
Fluid genesis, migration and fluxes, mineral formation, C-cycle, gas hydrate formation/dissociation, biogeochemical processes, ecology, mapping techniques and modelling are topics that have to be addressed for a better understanding of how these fluid systems function. This is especially important given the impact submarine fluid systems have on the environment and the potential for utilizing the vast resources, e.g. in deep sea mining and gas hydrate exploitation.
This session explicitly seeks to invite integrated studies covering all aspects of marine research around hot and cold venting, including geophysics, geology, geochemistry, oceanography, and biology, with the aim to understand and model fluid flow from small (single vents) to large (margin-wide) scales. It is also intended to provide an overview of what has been done in the past, is currently ongoing/planned, and identify gaps in our knowledge to be addressed in the future.
