  • The data set comprises trace metal and isotope data from the GEOTRACES programme. The data set incorporates the core GEOTRACES parameters for example, Iron (Fe), Aluminum (Al), Zinc (Zn), Manganese (Mn), Cadmium (Cd), Copper (Cu), delta 15 Nitrogen, delta 13 Carbon, Thorium (Th) isotopes, Protactinium(Pa) isotopes, Lead (Pb) isotopes, Neodymium (Nd) isotopes and aerosols, These data are also supported by ancillary measurements. GEOTRACES is global in scope and consists of ocean sections complemented by regional process studies. The ocean sections are designed to cross regions that provide the most information about sources, sinks and internal cycling of trace elements and isotopes (TEIs). The programme started in 2006, with the first International Polar Year - GEOTRACES cruise, and aims to study all major ocean basins over the next decade. Advances in clean sampling protocols and analytical techniques provide an unprecedented capability for measurement of a wide range of TEIs. All measurements collected for GEOTRACES will use ultra clean techniques as many of the countries involved have built specialist winches, wires and conductivity-temperature-depth (CTD) units specifically for this programme. SAFe standards (standards developed following the Sampling and Analysis of Fe (SAFe) cruise) and GEOTRACES inter-calibration protocols provide quality control.The GEOTRACES programme builds on the data collected during the Geochemical Ocean Section Study (GEOSECS) in the 1970s. The potential afforded by advances in sampling protocol and analytical techniques had not been realized since then, largely because of a lack of coordinated research. The GEOTRACES programme includes scientists from approximately 30 nations, although the key countries are the UK, Germany, France, Spain, Sweden, Netherlands, USA, Canada, New Zealand, Australia, Japan, India and China.

  • This dataset contains data collected during the integration and demonstration of the newly developed SenseOCEAN multifunctional sensor package. The data were collected from field tests in Kiel Fjord (Germany), the Baltic Sea and the Mediterranean Sea in September 2016 and May 2017. New marine chemical sensors (such as optode sensors (O2, CO2, NH3, pH), lab on chip (LOC) sensors (NO3-, NO2-, PO43-, Fe2+, pH) and electrochemical sensors (silicate, N2O)), an integrated multifunctional sensor, plug and play Modbus module and data assembly centre were developed by the EU consortia, SenseOCEAN. The consortia consisted of TU Graz, Pyro Science GmbH, Chelsea Technology Group, Aarhus University, Alfred Wegener Institute (AWI), CNRS-LEGOS, Max Planck Institute, nke Instrumentation, TE Laboratories, University of Southampton, National Oceanography Centre (NOC), Unisense A/S and the British Oceanographic Data Centre (BODC). The sensors and Modbus module were deployed for demonstrations on various platforms including CTD Rosettes, fixed-position pontoons and NKE PROVOR profiling (ARGO) floats. The data were collected as part of the SenseOCEAN Collaborative Project funded by the European Union Seventh Framework Programme (FP7/2007–2013) under grant agreement No. 614141. The main aim of the SenseOCEAN project was to develop new chemical sensors for in situ measurements of the marine environment and to combine these to produce an integrated multifunctional biogeochemical sensor package. The coordinator was Professor Douglas Connelly at the National Oceanography Centre, Southampton, UK. The data are held by BODC as a series of ASCII data files conforming to the NASA AMES 1001 format together with a PDF document that describes the data set.

  • This data set comprises hydrographic measurements including temperature, salinity, fluorescence, attenuance, dissolved oxygen concentrations and current velocities. Water samples were also collected for salinity and geochemical analysis, and the data set also includes bathymetric, sediment and upper ocean turbulence measurements. The data were collected over six Science Missions at the Strait of Sicily, West Coast of Scotland (Loch Etive and Loch Fyne), North-East Scotland and Shetland Islands, North Weddell Sea, Isles of Scilly, Southern North Sea (Norfolk Bank) over the period 19 April 1999 – 25 May 2001. The data were collected by both shipboard sensors and those attached to the Autosub (Autonomous Underwater Vehicle) package. Shipboard data collection included deployment of a conductivity-temperature-depth (CTD) package with attached auxiliary sensors. Lowered acoustic Dopper current profilers (LADCPs) were also attached to the CTD frame, while discrete water samples were collected from the CTD stations. Oceanographic, bathymetric and sediment data were collected along the ship’s track. Autosub measurements included standard environmental parameters and acoustic instruments were used to measure ocean bottom relief at high resolution. A camera was also attached to the vehicle, permitting the collection of detailed photographs of the seabed. The broad aims of the Autosub Programme are the collection of interdisciplinary data sets that cannot be obtained by research ships, and demonstration to the scientific and wider user community of the usefulness of an AUV. Investigators: David A Smeed, Kate Stansfield, Julian Overnell, Kenny D Black, Peter Statham, Chris German, Andrew S. Brierley, Paul G. Fernandes, Mark A. Brandon, Alex Cunningham, Peter Burkill, Glen Tarran, Prof. Mike Collins, Dr George Voulgaris, Dr John Trowbridge, Dr Eugene Terray, Steve A Thorpe and Thomas Osborn. The British Oceanographic Data Centre holds the Autosub navigation files, CTD and ADCP data for each of the missions listed above. The data are contained as high resolution time series. The data are presently being processed and have not been fully quality controlled. The Autosub science missions brought together researchers and engineers from a number of UK institutions, with the project being coordinated by the National Oceanography Centre, Southampton.

  • This dataset comprises 41 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during April - May 1993 from stations in the English Channel, Bay of Biscay, Ria de Vigo, Ria de Arosa and Ria de Muros.

  • The data set comprises hydrographic and biogeochemical and biological measurements including temperature, salinity, currents, chlorophyll, dissolved organic and inorganic carbon and nitrogen, suspended matter concentrations, nutrients, plankton and fish. The results of primary production experiments are also included. The data were collected from the Bristol Channel, Severn Estuary, Celtic Sea and Plymouth Sound between 1971 and 1983. Measurements were taken over a series of more than 100 cruises, many with more than 50 stations. The most intensive sampling took place before 1975. The original data were collated and stored at Institute for Marine Environmental Research (IMER), which became Plymouth Marine Laboratory in 1988. As this is a large and important data set, which was previously held in an inaccessible format, it was selected for long-term archival at BODC as part of the NERC SEEDCORN programme. The data have been extracted, loaded into a relational database and are available on CD-ROM.

  • The dataset contains a diverse range of environmental data ranging from estuary properties including geomorphology, water depth and habitat characterisation to detailed time series of parameters such as salinity and chemical and nutrient concentrations. The data are stored in a database containing a directory of existing data sources for estuaries; data for the broad properties of 79 UK estuaries; and detailed hydrodynamic, bathymetric, and sedimentary information for six estuaries: Blackwater, Humber, Mersey, Ribble, Southampton Water and Tamar. The data range from 1965 to 2002 and include both historic datasets and those collected during a recent effort (1997-2002) to enhance our knowledge of estuaries. Data collection employed a variety of instrumentation and techniques, including water, biota and sediment sample collection and analysis and the deployment of hydrographic instruments such as sea level, temperature, salinity and optical backscatter recorders. The Estuaries Research Programme (ERP) began in 1997 with the EMPHASYS project, which aimed to improve our understanding of processes operating in estuaries and use this knowledge to enhance broad scale modelling techniques that can be applied to estuarine processes. This work was funded by the Environment Agency/Department for Environment, Food and Rural Affairs (DEFRA) Flood and Coastal Defence Research and Development Programme. The data are managed by the British Oceanographic Data Centre (BODC) and are available on CD-ROM.
