This layer forms one of a set of data layers created for the Defra MB0102 contract. This work will support the delivery of a network of Marine Protected Areas as required to meet existing international and national obligations and commitments, including Marine Conservation Zones (MCZs), a new measure to be delivered as part of the Marine and Coastal Access Bill, and equivalent measures under Scottish legislation. The availability of these data layers will also be of importance in underpinning Marine Planning (e.g. licensing) in our marine area.

Data was collated from a range of conservation and academic organisations and through a literature search. The survey used to collate the point data are: MRMLN004000000E0 - 1999 Plymouth Perophora japonica records MRMLN004000000E1 - 2000 Fleet Perophora japonica record MRMLN004000000EA - 2004 South coast of England Alien species marina search MREN016000000002 - 2002 Chesil and the Fleet cSAC Fleet Lagoon and Tidal Rapids Survey MRCCW80000000003 - 2002 CCW/CALM Milford Haven and Daugleddau Estuary tidally exposed seabed and shores MPALAYERS000040 - 2009 John Bishop Perophora Personal Comments Full survey information is available from the survey table in the project geodatabase which can be joined to the layer by the Survey ID Field Explanations. Original Scientific Name: The scientific name (or in some cases the common name) recorded in the original survey. Scientific Name: The current accepted name for the taxon using WORMS as the definitive species list. See link: www.marinespecies.org Survey ID: A link to survey information. Where data is entered in to Marine Recorder this refers to the MR SurveyID. A few surveys could not be entered into Marine Recorder without risk of duplication occurring. e.g. Seasearch data that will be entered into MR at a later date, data from polygons etc. These have been given a project surveyID using the reference: MPALAYERS0000XX Date: The date the species was recorded. Vague dates have been entered as the first of a month, if only the month is known, e.g. 01/03/89 or as the first of January if only the year is known, e.g. 01/01/78. Unknown dates show as 00:00:00. Location Name: The location or site name where provided. SampleID: For Marine Recorder surveys the sample_key field has been entered. Event name: Where known an event name has been provided. Latitude: The latitude of the sample point. Longitude: The longitude of the sample point. Determiner: Where known the determiner of the species record as specified in Marine Recorder. For non MR surveys the recorder has been inputted into this field as it has been assumed that the recorder is the determiner unless otherwise stated. Status: The species status as defined by three terms; Present - the default indicating the presence of a species. Absent - Absence records have only been included in a small number of cases where a key historical population has disappeared. Uncertain - Indicates that the identification of the species may be incorrect and further investigation is required. Coordinate Precision: An estimate of the spatial resolution in metres of the co-ordinate, based on survey method, date and the derivation of the co-ordinates . This ranges from 10-10000 metres.
