Coastal Biodiversity and Ecosystem Service Sustainability (CBESS) surface sediment chlorophyll concentrations in saltmarsh and mudflat habitats
The dataset details surface sediment chlorophyll concentrations across six intertidal sites in the winter and summer of 2013. Chlorophyll concentrations in surface sediments (<2mm) provide a quantitative measure of the microphytobenthos (MPB) community present. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England, each of these sites consisted of a saltmarsh area and adjacent mudflat area, twenty two sampling quadrats were placed on each area. Five replicate sediment samples were taken at each quadrat and then underwent acetone extraction of pigments followed by spectrophotometer analysis of absorptions at relevant wavelengths. Values for chlorophyll a, b and c1+ c2 are expressed as micrograms per gram of sediment. This data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme. BESS is a six-year programme (2011-2017) funded by the UK Natural Environment Research Council (NERC) and the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the UK's Living with Environmental Change (LWEC) programme.

Sediment chlorophyll content was determined through the collection of contact cores. Contact cores use liquid nitrogen to freeze the top 2mm of the sediment surface, excess unfrozen sediment is removed and sample core is stored below -80 degree centigrade to ensure preservation of pigments. The sample is freeze dried to remove all water and a sub-sample taken. Acetone is added to the sediment sample and stored at -20 degrees centigrade for 48 hours to allow extraction of pigments. The sample is centrifuged and supernatant is analysed in a spectrophotometer for absorption at wavelengths 630, 647, 664 and 750 nanometres (nm). Values for chlorophyll a, b and c1+ c2 are expressed as micrograms per gram of sediment. The location of the sample sites was determined by randomly allocated quadrats. Twenty two 1 x 1 m quadrats were randomly allocated to each mudflat and saltmarsh site using R (R Development Core Team, 2014) to specify four different spatial scales (A = 1 quadrat only, B = 3 quadrats at 1 m to 10 m apart, C = 6 quadrats at 10 m to 100 m apart, D = 12 quadrats at 100 m to 1000 m or site maximum).
