The majority of the data were collected by members of the British Phycological Society as part of the Marine Algae Recording Scheme (http://www.brc.ac.uk/recording_schemes.asp) and were published in the 2003 atlas (see below).","EngDescr":"The point data were generated using nomenclature supplied from the AlgaeBase database (www.algaebase.org), developed by Prof. M.D. Guiry, Martin Ryan Institute, National University of Ireland. \r\n\r\nA small number of records are derived from the NCC River Macrophyte Database but the major divisions in the dataset are as follows:\r\n\r\nPurpose of data capture: To provide phycologists and scientists with a distribution map of algal species and encourage future mapping. Also to enable the monitoring of the spread of non-native species like Sargassum muticum and Undaria pinnatifida. \r\n\r\nMethods of data capture: Records were submitted by a variety of volunteers and professionals. The validity of submitted records was checked with the help of two panels of referees. Members of one panel were species experts and members of the other had local geographical knowledge and could consider the likelihood of a species being found in a particular place. Doubtful data were not included. \r\n\r\nGeographical coverage: The dataset contains coastal and estuarine records for many parts of the British Isles. Coverage of certain groups relied on very few experienced recorders and because of this, the entire coastline is not covered for all species groups. This may affect the interpretation of data for some species. \r\n\r\nTemporal coverage: Records span 1750-2003 with peaks at 1950, 1960 and 1999. There is sustained recording effort between 1966 and 1988. \r\n\r\nData quality: The data were validated and verified by members of the Recording Scheme, although according to the atlas, few records are supported by herbarium specimens. Records may not exist for some species while others may be under-recorded. \r\n\r\nThis dataset is held by the Biological Records Centre and was used in the publication of:\r\nHardy, F.D. & Guiry, M.D (2003) A Check-list and Atlas of the Seaweeds of Britain and Ireland. London: British Phycological Society\r\n\r\nThe full tekst can be viewed on the BPS website as a PDF document.\r\n\r\nThis atlas also contains related data that can be found in the following NBN Gateway datasets:\r\n
