An industry-acquired (2002) 3D seismic survey over the Mallik area in is used to map heterogeneities in permafrost and to determine the extent of gas hydrate occurrences. Seismic amplitude anomalies associated with lakes and drainage systems are observed in the data. Beneath lakes, the seismic indic...
