      <gmd:abstract>
        <gco:CharacterString>The CARBON-OPS data set comprises partial pressure of carbon dioxide (pCO2) and ancilliary parameters, measured aboard selected UK research vessels between 2007 and 2008. The parameter suite includes geographical position; partial pressure and fugacity of CO2; sea surface temperature, salinity, and dissolved oxygen concentration; air pressure, temperature and humidity; occasionally the parameter suite also includes fluorescence, transmittance, wind speed and direction. CARBON-OPS, led by Nick Hardman-Mountford at Plymouth Marine Laboratory, was funded by the Natural Environment Research Council under the Knowledge Transfer initiative (2007-2009). The aim of the project was to develop an automated supply chain of ocean surface and atmospheric carbon dioxide measurements from research ships to operational end-users. The data were first provided in near real-time following an initial level of automated quality control and processing. Following a secondary level of manual quality control and processing (delayed mode) the data are integrated into the BODC National Oceanographic Database. Measurements were taken aboard five UK research vessels: RRS Discovery, RRS James Clark Ross; RRS James Cook; RV Plymouth Quest; and RV Prince Madog.</gco:CharacterString>

The measurements and supporting data are sent in near real-time via Iridium satellite communications to Plymouth Marine Laboratory. They are then forwarded daily to the British Oceanographic Data Centre (BODC) to undergo an initial level of automated quality control and processing, prior to being loaded in the BODC CARBON-OPS database. A complete list of the automated quality control and processing procedures applied to CARBON-OPS data is available at http://www.bodc.ac.uk/carbon-ops/data/processing/.&#xD;Instrument(s) used to collect data: anemometers; meteorological packages; fluorometers; thermosalinographs; continuous water samplers; salinity sensor; dissolved gas sensors; geothermometers; continuous air samplers; Differential Global Positioning System receivers; transmissometers; water body temperature sensor; water temperature sensor.</gco:CharacterString>
