  • The dataset details organic carbon content of sediments across 6 intertidal sites in the winter and summer of 2013. The data provide a quantitative measure of the organic carbon present within surface sediments (up to a depth of 2 cm). Three sites were located in Essex, South East England and the other 3 in Morecambe Bay, North West England. Each site consisted of a saltmarsh habitat and adjacent mudflat habitat. 22 sampling quadrats were placed in each habitat covering 4 spatial scales. 3 replicate samples of surface sediment were collected at each quadrat. They were then processed for organic carbon content using the Loss on Ignition method (detailed below) Values are expressed as a percentage of the total sample collected. 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.

  • This dataset contains results from in situ field measurements of riverbed nitrogen transformations in the Hammer Stream, a sandy tributary of the River Rother in West Sussex, UK. Measurements were performed in November 2014 and February, April and July 2015. The data include baseline concentrations of nutrients (NO2, NO3, NH3, PO4), chloride, oxygen, pH, temperature, Fe(II), organic carbon, 15N-N2 and methane (CH4) and nitrous oxide (N2O) sampled from porewater prior to injection of 15N-nitrate.

  • The dataset comprises of physical property and biogeochemical measurements of saltmarsh soil collected using the hammer coring technique from the Kyle of Tongue saltmarsh in the North of Scotland. The site was chosen to represent northern, loch head marshes and to test different coring techniques in organic rich soils. The data provides a quantitative measure of the dry bulk density, water content, porosity and organic carbon content present within the soils of the Kyle of Tongue saltmarsh. A total of 4 cores were collected, 39 samples were collected at 10cm intervals down the length of each core. The samples were processed for bulk density, water content, porosity and organic carbon content which was quantified through elemental analysis. The data were collected to help create a detailed picture of saltmarsh carbon storage in the soils of UK saltmarsh and test different coring approaches. The cores were collected by the data authors in November 2018. The work was carried out under the NERC programme - Carbon Storage in Intertidal Environment (C-SIDE), NERC grant reference NE/R010846/1 Full details about this dataset can be found at https://doi.org/10.5285/b57ef444-54d4-47f9-8cbf-3cfef1182b55

  • The data provide a quantitative measure of the dry bulk density, soil texture, organic matter content (LOI) and organic carbon present within surface soils (up to a depth of 10 cm). A total of 212 samples from 49 sites across England and Wales were collected using modified syringe samplers as part of the citizen scientist programme CarbonQuest, part of Carbon Storage in Intertidal Environments (C-SIDE) project. Sites were chosen to represent contrasting habitats across England and Wales, in particular sediment types, vegetation and sea level history.The samples were processed for bulk density, soil texture, organic matter content using the Loss on Ignition (LOI) method and the organic carbon was quantified through elemental analysis. The data were collected to help create a detailed picture of saltmarsh carbon storage in surficial soils across England and Wales. The work was carried out under the NERC programme - Carbon Storage in Intertidal Environment (C-SIDE), NERC grant reference NE/R010846/1 Full details about this dataset can be found at https://doi.org/10.5285/e5554b83-910f-4030-8f4e-81967dc7047c
