Highlights • A saline formation fluid originated from great depths was documented. • Gas hydrates are currently at a dynamic equilibrium due to the low methane flux. • Fluids were diverted by the buried seep carbonates in Lunde pockmark. Abstract Seafloor seepage sites along the Vestnesa Ridge off w...
