HELCOM Metadata catalogue
Submarine structures made by leaking gas (1180)
Submarine structures made by leaking gases (according to Habitats Directive Annex I) are also known as “bubbling reefs”. These formations support a zonation of diverse benthic communities consisting of algae and/or invertebrate specialists of hard marine substrates different to that of the surrounding habitat. The distribution map is based on data submission by HELCOM contracting parties. Only Sweden and Denmark reported occurrences of submarine structures made by leaking gases.

Data source:
Denmark: Polygon and point data on the distribution of submarine structures made by leaking gases. Source: Danish Nature Agency.
Estonia: No reported submarine structures made by leaking gases.
Finland: No reported submarine structures made by leaking gases.
Germany: No reported submarine structures made by leaking gases.
Latvia: No reported submarine structures made by leaking gases.
Lithuania: No reported submarine structures made by leaking gases.
Poland: No reported submarine structures made by leaking gases.
Russia: Habitats Directive not implemented.
Sweden: Polygon data of potential pockmarks based on bathymetric data. Source: Swedish Agency for Marine and Water Management (HaV)
Data quality:
Data quality and habitat definitions vary between countries. Data is often based on modelling and ground-truthing has not always taken place.
The dataset was approved by all HELCOM Contracting Parties in the HOLAS II Ecosystem component data review process during first quarter of 2017 after corrections from Denmark.
Attribute information: Raster value representing presence (1) or absence (0) of submarine structures made by leaking gas.
