MIDAS scientists have returned from a successful cruise in the Black Sea, and are now busy processing huge volumes of seismic data. The cruise aboard the German research vessel, RV Maria S. Merian, spent six weeks over the 2013/14 festive period examining gas hydrate accumulations in the ancient Danube delta. An extensive 2D and 3D seismic survey was carried out, identifying a number of inactive and partly buried channel systems and the presence of gas hydrates in the overlying sediments.
