Subsurface Fluid Flow and Material Transport

Abstract

Submarine subsurface fluid flow is ubiquituous with rates varying enormously with space and time. Therefore, fluid flow most probably is of paramount importance for the transport of matter and heat as well as to control fluxes between the subsurface and the ocean. However, rates to date still are only very poorly understood. In this study we therefore first identify major fluid flow systems including fault transport at active and passive margins, gas hydrate affected flow systems, or submarine groundwater discharge. Then, we describe geophysical and geochemical methods which are capable to better and quantitatively understand interacting submarine fluid flow systems and lastly, propose strat..
