The various physical-chemical features of microniches of this ecosystem (darkness, lack of O2, increased levels of H2S and CH4 \u2013 in Movile Cave; strong light, high temperature (up to 40\u00b0C in summer) and O2 \u2013 in the terrestrial sulphidic springs; dim light, increased concentration of salts, variable temperature \u2013 in the case of submarine springs) are mirrored by different structures of the microbial communities providing insights on the origin of such ecosystems and a better understanding of how an isolated subsurface ecosystem evolves and adapts to such conditions.\r\nThe aquifer has numerous resurgences in the form of terrestrial and underwater (on the bottom of the sea) sulphidic springs.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1990,"yearClosed":null,"relatedSites":null,"siteName":"Sulphidic aquifer of South Dobrogea","shortName":"Movileaquif","siteType":"Stationary land-based site","protectionLevel":[{"label":"Category IV \u2013 Habitat\/Species Management Area","uri":"http:\/\/dd.eionet.europa.eu\/vocabularyconcept\/cdda\/IucnCategoryValue\/IV"},{"label":"Category Ia \u2013 Strict Nature Reserve","uri":"http:\/\/dd.eionet.europa.eu\/vocabularyconcept\/cdda\/IucnCategoryValue\/Ia"}],"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/Google_sulfuros.jpg","alt":"GoogleEarth image of aquifer "},{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/IMG_0605_0.jpg","alt":"Shallow undersea sulphidic spring"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/PB190066.JPG","alt":"Deep undersea sulphidic spring"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/Biofilm%20riu_1.JPG","alt":"Microbial biofilm in sulphidic terrestrial spring"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/PB190066_0.JPG","alt":"Deep undersea sulphidic springs"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/IMG_9646_0.JPG","alt":"Movile cave_gallery"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/Movile%20Cave_Foto%20Petr%20Zaj%C3%AD%C4%8Dek_0.jpg","alt":"Movile cave_Lake Room"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/IMG_6026Used%20by%20Alberto%20Sendra_2021.JPG","alt":"Movile cave_Microbial biofilm in AirBell II"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2023-11\/AHV_Clopot%20I.JPG","alt":"Movile cave_AirBell I"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":13,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":{"label":"Other, non-standardised or incomplete reference period","uri":null}},"precipitation":{"yearlyAverage":299,"monthlyAverage":null,"unit":"mm","referencePeriod":{"label":"Other, non-standardised or incomplete reference period","uri":null}},"biogeographicalRegion":"blacksea","biome":null,"ecosystemType":[{"label":"Coastal","uri":null},{"label":"Lakes","uri":null},{"label":"Marine","uri":null},{"label":"Rivers","uri":null}],"eunisHabitat":[{"label":"Coastal habitats (B)","uri":null},{"label":"Inland surface waters (C)","uri":null},{"label":"Marine habitats (A)","uri":null}],"landforms":[{"label":"Cave","uri":null},{"label":"Coast","uri":null},{"label":"Lake","uri":null},{"label":"River","uri":null},{"label":"not applicable\/not relevant","uri":null}],"geoBonBiome":["Marine","Coastal","Fresh water lakes","Fresh water rivers"],"geology":"Karst region developed in Sarmatian and Neogene limestone.","hydrology":"Karst region, with deep sulphidic water resurging inland, on the bottom of fresh water lakes and on the Black Sea bottom as sulphidic springs.","soils":null,"vegetation":"Since the site covers both land and sea, the vegetation is very diverse.
