The habitat was recorded using a MiniRov Observer on a large outcrop at ca. 55–60 m in the Luiz Saldanha Marine Park. A method to estimate the maximum uncertainty of the ROV position is illustrated and the occurrence of the facies is discussed.engcircalittoralLuiz Saldanha Marine Parkmono-specific faciesParazoanthus axinellaeROV position uncertaintysouth-west Portugaljournal article10.1017/s1755267215000597
