Metadata: 2007-2008 North Sea Sediment Oxygen Profiles
Abstract:
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.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 10488 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 2007-2008 North Sea Sediment Oxygen Profiles |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFASada68af3-ffa8-479d-87fb-a628fbbc4525 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS912 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2007-01-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2008-12-31 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |
| Abstract | The abstract provides a clear and brief statement of the content of the resource. | 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. |
| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | 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) 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 |
