Potential Annex I submarine structures made by leaking gases

 

The map shows the location of known Annex I submarine structures made by leaking gases. It also shows areas where gas seeps are known to occur and therefore where there may be additional submarine stuctures that have not yet been found. For information on the identification of SACs for submarine structures made by leaking gases within 12 nautical miles of the coast, please contact the relevant country conservation agency.

 

There are currently only  five known locations of submarine structures made by leaking gases in the UK, as highlighted on the map. The map also displays ‘fluid seep’ areas where gases are known to seep up from below the seabed.  Methane gas seepage from the seafloor mixing with seawater can react under certain conditions to form carbonate rock (MDAC), therefore the range of this known fluid seepage can be used as an indicator for where there may be other, as yet undiscovered, occurrences of submarine structures made by leaking gases in the UK.
