This dataset records the depth to which free oxygen is available in seabed
sediments; referred to as the Oxygen Penetration Depth (OPD). It also includes
the original oxygen profile data, recording the depeletion of oxygen as the
sediment is penetrated. Samples were collected from sites in the North Sea:
Northern Dogger Bank, Oyster Ground and Sean Gasfield during various cruises
on RV Cefas Endeavour throughout 2007 and 2008.

dataset
The standard methodology comprises driving a very fine metal-in-glass oxygen probe into undisturbed core
samples recovered from the seabed using a box corer (NIOZ design). The probe is driven ino the sediment
in millimetre depth increments, recording the 'oxygen profile' which can be displayed graphically. The
depth at which the probe first records zero oxygen is the Oxygen Penetration Depth.
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)
