 The steady investigated fluid seepage within pockmark fields off mid Norway using remotely operated vehicle dives revealing that present day methane rich fluid seepage through the seabed is indicated by chemosynthetic fauna and microbial mats. The presence of orthogenic carbonates indicates past seepage with very low delta-1 3C values and vesicamiad bivalve shells provide ages for major periods of methane venting corresponding to meltwater pulse IA. The seafloor morphology and pattern of seepage are heterogeneous with poor water chemistry profiles indicating no seepage and anaerobic methane oxidation at a sub-bottom depth.
