Sediment Particulate Organic Carbon in Marine Sediments around England and Wales 1996 - 2017
Summary
Sediment particulate organic carbon (and nitrogen) data from marine samples collected between 1996-2017 around England and Wales. Measurements for less than 2mm sediment fraction or/and less than 63 micron sediment fraction are given. Silt/clay percentage is also included (for either/both sieving and laser methodologies) as well as sample weight where available. These data have been collated from a variety of sources, including CSEMP monitoring, nephrops monitoring, fishing pressures research and the NERC shelf seas programme to support on-going investigations for the Cefas/Defra project ''Operational indicators of seafloor integrity'. This new revision includes new data from samples collected in 2015 to 2017, including CSEMP monitoring and MPA monitoring surveys (core as well as surface). The work to create this revision was conducted under work package 5 “Data Synthesis and Management of Marine and Coastal Carbon” (C6090, NE/K001914/1) of the Shelf Sea Biogeochemistry programme jointly funded by the National Environment Research Council (NERC) and the Department for Environment, Food and Rural Affairs (Defra) of the United Kingdom.

Lineage
Sediment organic carbon (and nitrogen) have been analysed using the following method. Sediment samples are freeze-dried. Any material greater than 2mm is removed. The sediment is ground (for sediment fraction less than 2mm only). Inorganic carbon is removed using a sulphurous acid digest. Sediment OC is measured using an elemental analyser. Silt/clay percentage is either derived from sieving (weight of dried sediment less than 63 microns divided by total weight of sediment as a percentage) and/or from laser diffraction. Station data included with the results include cruise code; station number; latitude; longitude; date sampled; relative depth of sample and grab type.
