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)

Mapping important areasWhat areas do you think are important and why?
