The data set has been interpreted and digitized by NGU, but the interpretations are based on data from the Geological Survey of Norway (NGU), the Norwegian Mapping Authority (SKS), the Norwegian Petroleum Directorate (NPD), Institutt for Kontinentalsokkelundersøkelser (IKU, present SINTEF), and previous interpretations and scientific publications. Various basic gas-related landforms and phenomena are described with SOSI codes. Among other things, it is stated whether the phenomenon can be seen on the seabed or whether it is buried or observed in sedimentary rocks / sediments.

The dataset is a collection of landforms and phenomena in and on the seabed caused by natural gas in the seabed sediments. Shallow gas can originate from both sedimentary rocks and overlying sediments. Typical landforms are pockmarks and diapirs, but shallow gas are also displayed as strong reflectors (bright spots) or gas blanking on seismic profiles. Gas leakage from the seabed has great ecological significance for plant and animal life in the sea, e.g. it is typical with bacterial mats occur around such places. Gas and gas hydrates in the sub-seabed sediments also have an impact on seabed stability and climate change.
