Ziel der Reise / Objectives of Cruise:

The TECFLUX programme addressed geophysical, biogeochemical and hydrographic processes associated with fluid venting and gas hydrate outcropping at the Hydrate Ridge off Oregon, USA. SO 143-2 was one of 8 expeditions in 1999 which led to Hydrate Ridge. Scientists from Germany, Canada, Japan and the USA participated in the TECFLUX programme. Investigation at SO143-2 concentrated on:- -methane plume detections (18kHz echosounder) and methane measurements in the water column (CTD/Ro casts) -visual observation of seep communities (OFOS) - sediment sampling with box grab and multiple corer (biogeochemistry, porewater geochemistry, microbiological investigations, faunal analysis) Lander deployments to measure benthic metabolism and in situ fluid flow. SO 143-2 started and ended in Astoria Oregon. USA. Investigations were restricted to the Hydrate Ridge area.
