Examination of the final map of interpreted slick-like features on the sea surface, revealed a close
correlation of some of these occurrences to several bathymetric features which have underlying seismic
signatures similar to previously identified gas hydrate “pipes” or chimney anomalies as seen in data from
offshore Nova Scotia and in the Irish Sea. Globally, many active marine hydrocarbon seeps appear on the
seafloor as “pockmarks”; in this case no seafloor depressions were seen on conventional multi channel 2-
D seismic data associated with active seepage. Instead, very distinct mound-like structures are seen
associated with seeps at two locations east of Hudson Strait. The presence of significant cold water coral
in close proximity to the active seepage sites may show a link between seafloor petroleum seepage and
coral reef development similar to that observed offshore Norway.
