This study investigates gas hydrate distribution in the Danube Fan, NW Black Sea. Using seismic data and drilling results, we analysed the structure, composition, and gas content of underconsolidated sediments. Gas hydrates are present in low concentration and patchy distribution. Free gas is trapped beneath the hydrate stability zone. The area shows signs of past slope failures linked to weak sediments and gas accumulation. The study provides insights into how gas hydrate systems evolve.
