World Atlas of Submarine Gas Hydrates in Continental Margins

As methane hydrate stability depends mainly on pressure, temperature, gas composition and pore water chemistry, gas hydrates are usually found in ocean margin settings where water depth is more than 300 m and gas migrates upward from deeper geological formations.

Deoarece stabilitatea hidratului de metan depinde in principal de presiune, temperatura, compozitia gazului si chimia apei din pori, hidratii de gaz se gasesc de obicei in zonele pe marginea oceanului unde adancimea apei este mai mare de 300 m si gazul migreaza in sus din formatiunile geologice mai adanci.
