Carbon, nitrogen and phosphorus concentrations of plant material and pond sediments collected at three seperate visits to Blakeney salt marsh, North Norfolk (UK). In October 2015 and August 2016, 2 replicate cores were collected from one pond with benthic fauna and one pond without benthic fauna. Organic carbon and total nitrogen measurements, as well as sequential phosphorus extractions ('SEDEX') were performed on these pond sediments. In August 2018, 4 ponds with benthic fauna and 4 ponds without benthic fauna (2 replicates each) were sampled. Organic carbon, total nitrogen, total and inorganic phosphorus measurements were performed on these sediments. Plant material was collected in August 2018 and analyzed for total carbon, nitrogen and phosphorus contents.
