Submarine structures made by leaking gases
Spectacular submarine complex structures, consisting of rocks, pavements and pillars up to 4 m high. These formations are due to the aggregation of sandstone by a carbonate cement resulting from microbial oxidation, mainly methane. The methane most likely originated from the microbial decomposition of fossil plant materials. The formations are interspersed with gas vents that intermittently release gas. These formations shelter a highly diversified ecosystem with brightly coloured species.

EU conservation status
Conservation status assesses every six years and for each biogeographical region the condition of habitats and species compared to the favourable status as described in the Habitats Directive. The map shows the 2013-2018 assessments as reported by EU Member State. Assessments are further detailed in the summary document available behind the link below.
