Current Posidonia oceanica meadows distribution (presence points) in the Mediterranean Sea from dataset Seagrass beds distribution along the Mediterranean coasts - Mediterranean Sensitive Habitats (MEDISEH). The dataset of seagrasses distribution across the Mediterranean produced in the framework of MEDISEH derived from the compilation of published and unpublished information. For example literature search was made using mainly the ISI Web of Knowledge engine. At the same time a new search started from the “Bibliographic References” at the end of each paper. We amended the data set with our own unpublished data (grey literature).
