Ziel der Reise / Objectives of Cruise:
The R/V POSEIDON cruise 317/4 takes place in the framework of the German-Russian WTZ cooperation and the German BMBF program METRO (METhane and methane hydRates within the Black Sea: Structural analyses, quantification and impact of a dynamic methane reservOir). The focus of the R/V POSEIDON cruise 317/4 is to investigate near-surface methane and methane hydrates in the Black Sea in order to understand their origin, structure, and behavior as well as their interaction with the sedimentary and oceanic environment. Using different techniques of seafloor mapping (multibeam bathymetry, deep-towed sidescan sonar and video observation) the aim of the cruise is to identify and map various facies and environments that are related to near-surface gas hydrates and methane seeps off the coast of Georgia and Turkey.
