Pore-water is the sea water held in the pore-spaces of marine sediments and was sampled using by a sipper system from 11 depth horizons in undisturbed sediment cores collected by a NIOZ box corer. Resulting water samples were filtered and analysed using a Skalar nutrient analyser.This data is used to determine where and how organic matter is decaying, as well as analysing sediment linkage to macronutrient cycles (N, P, Si) via nutrient fluxes or uptake across the sediment-water interface. Samples were collected from three sites (North Dogger Bank, Oyster Ground, Sean Gasfield) in the North Sea during various cruises throughout 2007 and 2008. Records include data from Defra funded project ME3205 entitled "Marine Ecosystem Connections: carbon and nitrogen fluxes through the benthic and pelagic domains" which sampled three fixed stations in the North Sea. Semi-autonomous in situ systems were deployed at each study site to follow temporal changes in environmental conditions such as temperature, light, nutrients, and chlorophyll fluorescence. Detailed studies of pelagic and benthic food webs were carried out during 8 research cruises spaced to capture seasonal changes (February , April, May, September, and October/November 2007; January, April and September 2008). Cruise sampling was focussed on identifying ecosystem structure, in terms of seabed types, physics, chemistry, and the abundance (as numbers and/or biomass) and diversity of planktonic and benthic communities (from micro- to macro- organisms). Experimental work was carried out to obtain estimates of the rates of key processes such as primary production, zooplankton secondary production, carbon cycling, and nutrient fluxes across the sediment-seawater interface (see Painting et al. 2010) Further details of the project can be found at: `http://randd.defra.gov.uk/Default.aspx?Menu=Menu&Module=More&Location=None&Completed=0&ProjectID=13011`_ .. _`http://randd.defra.gov.uk/default.aspx?menu=menu&module=more&location=none&completed=0&projectid=13011`: http://randd.defra.gov.uk/Default.aspx?Menu=Menu&Module=More&Location=None&Completed=0&ProjectID=13011 MEDIN 3.1.1
