Young Fish Survey Data 1981 to 2010

Total numbers of individual fish identified during the Cefas Young Fish Survey (YFS) which ran from 1981 to 2010. The survey deployed a light 2-meter beam trawl to survey inshore locations for small / young fish around the British Isles, predominantly along the south and east coasts. Total numbers of fish (identified to species or if not to the highest taxonomic level) were recorded at each station, and were measured in the majority of cases....

Modelled gridded data of aquaculture potential in the Dorset and East Devon Fisheries Local Action Group area, 2018-2019

Gridded data (GeoTiff format) produced in the context of the FLAG Aquaculture Mapping project (2018-2019). The purpose of the project was to identify and map areas best suited (and with least conflict) to specific types of sustainable marine aquaculture, within the boundaries of the Dorset and East Devon Fisheries Local Action Group (FLAG) area. The aquaculture potential layers were derived by combining information on conservation and legislative boundaries, human infrastructure and activity constraints, with environmental...

Gridded data (GeoTiff format) produced in the context of the FLAG Aquaculture Mapping project (2018-2019). The gridded layers were derived by modelling a suitability score based on environmental requirements for each specific combination of species and culture method. The purpose of the project was to identify and map areas best...

Modelled vector layers (shapefiles) of spatial extent of aquaculture potential in the Dorset East Devon Fisheries Local Action Group area, 2018-2019

Polygon shapefiles converted from modelled raster layers of aquaculture potential, with values ranging between 0 (representing no potential) and 1 (representing full potential). The underlying raster layers were derived by combining conservation, legislative, human infrastructure features and activity boundaries with environmental requirements for specific aquaculture species/system combinations. The polygon boundaries delineate aquaculture potential areas with a modelled raster classification of 0.5 or higher (i.e. 50% of threshold values are optimum for the specific species/system combination)....

Connectivity matrices for seven benthic species

These are connectivity matrices calculated from the results of Lagrangian models (GITM forced with GETM) for the period 2001-2010 and for seven benthic species: Alcyonium digitatum, Echinus esculentus, Lophelia pertusa, Metridium senile var. dianthus, Porifera, Mythilus edulis and Crepidula fornicata. The paper describing the calculation of these matrices and the analysis can be found in: https://www.nature.com/articles/s41598-018-32912-2.The data were produced by analysing the results of the Lagrangian model GITM. The connectivity was calculated between the sectors...
