ScanFish – North and Celtic Seas

David Morris
This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled. ScanFish is a high performance towed undulating CTD which was deployed by Cefas, initially, to aid the understanding of the coupling between physical and biological processes (Brown et al., 1996). It was towed behind the vessel at approximately 8 knots and undulated from...

Cefas Coastal Temperature Network

David Morris
The Coastal Temperature Network consists of Cefas (and predecessor) originated data and data from external suppliers, who have agreed their data can be published as part of the network (Jones, 1981). The earliest data are from 1875 (Owers Light vessel) and have been supplied by the Met Office. The longest continuous record provided here is from Eastbourne (1892–2014). Sampling is from piers and breakwaters 50-200m from the shore where possible (Jones, 1981). The present network...

Cefas SmartBuoy Monitoring Network

David Morris
This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled. SmartBuoys are autonomous marine monitoring systems making high frequency measurements of physical, chemical and biological parameters (Greenwood et al., 2010). They have been deployed as part of the UK marine eutrophication monitoring programme. Sea surface temperature is measured using an FSI or Aanderaa...

David Morris
This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled. WaveNet, Defra's strategic wave monitoring network for the United Kingdom, provides a single source of real-time wave data from a network of wave buoys located in areas at risk from flooding. In operation since 2002, WaveNet collects and processes data from the Cefas-operated...

Cefas Electronic Data Storage-Tag Database

David Morris
This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled. Electronic tags that record temperature and depth were attached to, or implanted into, cod caught in the southern North Sea between 1999 and 2009 (for methods see Neat et al., 2014). Data from tags that were returned from recaptured cod were downloaded and...

Cefas Historic Secchi Depth Measurements

Elisa Capuzzo
Secchi depth measurements, collected for studying the effects of the light climate on pelagic fish (e.g. fish school position in the water column compared to the depth of penetration of light); The dataset comprise 470 Secchi depth measurements collected in 1931, 1937, 1946-1950, 1968. The coordinates of each observation were generally not indicated in the logbooks and were derived from the associated station-sheets. Occasionally the exact coordinates were not specified but only the location of...

Large Woody Debris Restoration Field Experiment Dataset

Murray Thompson
Riverine species and environmental data relating to Thompson et al. (2017) Large woody debris rewilding rapidly restores biodiversity in riverine food webs. Journal of Applied Ecology. The purpose of this study was to test for causal evidence of ecological restoration following the introduction of large woody debris in rivers. Chlorophyll-a and diatom community structure was estimated from stone scrapes; a Hess sampler (0.017m2) with 335µm mesh was used to collect invertebrates and coarse (CPOM) and...

One file contains spectrum analysis for some of the particles carried out with a ATR-FTIR. A READ-ME text file contains description of columns content for these two csv files. There is a .zip file that includes a csv file with the description of...

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....

Fladen experimental fishing impact recovery data - Acoustic data

Output imagery of multibeam echosounder backscatter (tiffs) from within six experimental boxes (three treatments and three control) during a fishing impact recovery survey within the Fladen Grounds. Data were collected at three time points (before impact (time 0), immediately after impact (time 1) and 8 months after impact (time 2) during two research surveys on the RV Cefas Endeavour in April 2015 and November 2015. One hundred percent multibeam bathymetry and backscatter data were acquired...

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

Modelled raster layers (GeoTiff format) of aquaculture suitability with values ranging between 0 and 1, where the value 0 represents unsuitable and 1 fully suitable. 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 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...

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)....
