Shelf Sea Biogeochemistry (SSB) Star-Oddi DST CTD, Star-Oddi Starmon mini temperature recorder and RBR Solo T Temperature logger data from temperature chain mooring BODC Processing

Data from three instruments arrived at BODC in Matlab files. The instruments were the Star-Oddi DST CTD, Star-Oddi Starmon mini temperature recorder and RBR Solo T Temperature logger. The following table shows how the variables within the files were mapped to appropriate BODC parameter codes:

Originator's Variable Units BODC Parameter Code Units Comment
temp °C TEMPPR01 °C -
depth m DPSAZZ01 m Depths were estimated from neighbouring instruments with pressure sensors by originator

The reformatted data were visualised using the in-house visualisation software. Suspect data were marked by adding an appropriate quality control flag. Missing data are set to an appropriate value and the corresponding flag added. Data in files from the first deployment of the mooring were removed before 26/03/2014 00:00:00, the instruments had been set to begin recording on 19/03/2014 but were not deployed until 26/03/2014 16:51 therefore, data before this time was collected while the instruments were on deck. Data prior to deployment and post recovery of the fifth deployment have also been removed due to the instruments being left to record data while on deck for significant time periods.

Sampling and acquisition

The following information has been taken from the method statement (see Wihsgott) provided to BODC by the originator.

A long term temperature and salinity chain was deployed in the Central Celtic Sea (CCS) as part of the Shelf Sea Biogeochemistry programme. Five consecutive deployments covered a period of 17 months, from March 2014 to July 2015. The chain was deployed with a vertical resolution of 2.5 m in the main pycnocline region and 5 to 20 m vertical resolution in the surface and bottom layers. Sampling interval was set to 5 minutes for all instruments.

An alongside bedframe mooring included a SBE16plus instrument that was processed with the instruments from the temperature and salinity chain. The moorings were deployed less than a kilometre apart.

Pressure and conductivity were only recorded by the SBE instruments (SBE16plus, SBE37). For these instruments depth, salinity and potential density (for calibration purposes only) were derived using the Gibbs-SeaWater (GSW) Oceanographic Toolbox (McDougall and Barker, 2011).

Calibration procedures

The moored instruments were calibrated against pre- and post-deployment CTD casts. Each instrument accuracy was also taken into consideration when applying the correction. Small scale instances of vertical instability were not removed by the originator.

Time drift was identified in some instruments however a correction was not applied to the data as it was considered negligible when compared with the sampling interval and deployment period.

Project Information

Shelf Sea Biogeochemistry (SSB) Programme

Shelf Sea Biogeochemistry (SSB) is a £10.5 million, six-year (2011-2017) research programme, jointly funded by the Natural Environment Research Council (NERC) and the Department for Environment, Food and Rural Affairs (DEFRA). The aim of the research is to reduce the uncertainty in our understanding of nutrient and carbon cycling within the shelf seas, and of their role in global biogeochemical cycles. SSB will also provide effective policy advice and make a significant contribution to the Living with Environmental Change programme.


The Shelf Sea Biogeochemistry research programme directly relates to the delivery of the NERC Earth system science theme and aims to provide evidence that supports a number of marine policy areas and statutory requirements, such as the Marine Strategy Framework Directive and Marine and Climate Acts.

The shelf seas are highly productive compared to the open ocean, a productivity that underpins more than 90 per cent of global fisheries. Their importance to society extends beyond food production to include issues of biodiversity, carbon cycling and storage, waste disposal, nutrient cycling, recreation and renewable energy resources.

The shelf seas have been estimated to be the most valuable biome on Earth, but they are under considerable stress, as a result of anthropogenic nutrient loading, overfishing, habitat disturbance, climate change and other impacts.

However, even within the relatively well-studied European shelf seas, fundamental biogeochemical processes are poorly understood. For example: the role of shelf seas in carbon storage; in the global cycles of key nutrients (nitrogen, phosphorus, silicon and iron); and in determining primary and secondary production, and thereby underpinning the future delivery of many other ecosystem services.

Improved knowledge of such factors is not only required by marine policymakers; it also has the potential to increase the quality and cost-effectiveness of management decisions at the local, national and international levels under conditions of climate change.

The Shelf Sea Biogeochemistry research programme will take a holistic approach to the cycling of nutrients and carbon and the controls on primary and secondary production in UK and European shelf seas, to increase understanding of these processes and their role in wider biogeochemical cycles. It will thereby significantly improve predictive marine biogeochemical and ecosystem models over a range of scales.

The scope of the programme includes exchanges with the open ocean (transport on and off the shelf to a depth of around 500m), together with cycling, storage and release processes on the shelf slope, and air-sea exchange of greenhouse gases (carbon dioxide and nitrous oxide).

Further details are available on the SSB website.

Research details

Overall, five Work Packages have been funded by the SSB programme. These are described in brief below:

  • Work Package 1: Carbon and Nutrient Dynamics and Fluxes over Shelf Systems (CaNDyFloSS).
    This work package aims to perform a comprehensive study of the cycling of nutrients and carbon throughout the water column over the whole north-west European shelf. This will allow the fluxes of nutrients and carbon between the shelf and the deep ocean and atmosphere to be quantified, establishing the role of the north-west European continental shelf in the global carbon cycle.

  • Work Package 2: Biogeochemistry, macronutrient and carbon cycling in the benthic layer.
    This work package aims are to map the sensitivity and status of seabed habitats, based on physical conditions, ecological community structure and the size and dynamics of the nitrogen and carbon pools found there. This information will be used, in conjunction with some laboratory-based work, to generate an understanding of the potential impacts on the benthic community as a result of changing environmental conditions, such as rising CO2 levels.

  • Work Package 3: The supply of iron from shelf sediments to the ocean.
    The research for this work package addresses the question of how currents, tides, weather and marine chemistry allow new iron to be transported away from the shallow shelf waters around the United Kingdom (UK), to the nearby open ocean. This will ultimately allow an improved understanding of how the transport of iron in shelf waters and shelf sediments influences phytoplankton growth in open oceans. This in turn improves the understanding of carbon dioxide uptake by phytoplankton.

  • Work Package 4: Integrative modelling for Shelf Seas Biogeochemistry.
    The aim of this work package is the development of a new shelf seas biogeochemical model system, coupled to a state of the art physical model, that is capable of predicting regional impacts of environmental change of timescales from days to decades. It is envisaged that the combination of predictive tools and new knowledge developed in this work package will underpin development and implementation of marine policy and marine forecasting systems.

  • Work Package 5: Data synthesis and management of marine and coastal carbon (DSMMAC).
    This work package is funded by Defra and is also known by the name 'Blue Carbon'. The aim is to provide a process-based, quantitative assessment of the role of UK coastal waters and shelf seas in carbon storage and release, using existing data and understanding, and also emerging results from SSB fieldwork, experiments and modelling. Particular emphasis will be given to processes that may be influenced by human activities, and hence the opportunity for management interventions to enhance carbon sequestration.

Fieldwork and data collection

The campaign consists of the core cruises in the table below, to the marine shelf (and shelf-edge) of the Celtic Sea on board the NERC research vessels RRS Discovery and RRS James Cook. These cruises will focus on the physics and biogeochemistry of the benthic and pelagic zones of the water column, primarily around four main sampling sites in this area.
