Sedimentary species data • Warwick and Davis• Outer Bristol Channel• RWE• EA grab sampling• NE Lundy sediment surveys• Andy’s Grab sampling• Lundy Field Society fauna lists • Marine Recorder

Sediment and habitats data • Warwick and Davis

Bristol channel sediments

• BIOMOR 4 (Outer Bristol Channel survey)

• Lundy habitat mapping surveys (Smith and Nunny 2008, Green 2012)

• Andy’s Grabs• EA grab sampling

Data Confidence• Groundtruthing with stakeholders• Using data collected to national standards

where available(e.g. Cefas, MMO, EA, NMBACQ Accredited consultancies, Statutory agencies, etc.)

• Quality Assurance (double checking things are where they say they are, and what they say they are, MESH confidence intervals.)

• Quality grading(saying how confident you are using different datasets)

• Stacking(comparing different datasets collected in the same area to see if they agree)

Additional Data – Can you help?

• Are we missing any important survey work? (see list on table for full data list)• Better understanding of activities and uses

that leave a footprint on the sedimentary habitats (especially fisheries activity).

• Better understanding of sediments. • Better and more detailed understanding of

spawning and nursery areas. • Better understanding of management

activities

Types of data we can takeAnything we can attach a specific or approximate spatial location to.

• GIS (electronic mapping)• Spreadsheets• Paper records• Reports• Dive log records• Local knowledge and descriptions (drawing on maps)
