Ziel der Reise / Objectives of Cruise:

Cruise SO165/ OTEGA I represented the first joint expedition of the collaborative projects LOTUS, OMEGA and MUMM to study the gas hydrate province at Hydrate Ridge (Oregon continental margin). All three projects are funded as a part of the research initiative "Gas Hydrates in the Geo-System" within the scope of the "Geotechnologien" programme of the German Ministry of Education and Research (BMBF). Main objectives: - deployments long-term observatories (lander) to measure fluid flows and to monitor mechanisms that control the formation and dissociation of gas hydrate. - exploration of near-surface gas hydrates structure and the conditions leading to their formation and dissociation. - determination the biogeochemical turnover and the role of micro-organisms in marine sediment containing gas hydrate.
