RAGNARoCC: Radiatively active gases from the North Atlantic Region and Climate Change (June 2014 onwards)

The RAGNARoCC dataset includes surface and deep ocean measurements of greenhouse gas concentrations including carbon dioxide, methane and nitrous oxide. The dataset was collected in the North Atlantic Ocean during the RRS James Clark Ross cruise JR20140531 (JR302) which surveyed from Canada, to Greenland, to the United Kingdom via Iceland. The JR302 cruise started on 6th June 2014 and finished on 22nd July 2014. Some water samples were analysed aboard ship, whilst others were subsequently analysed ashore. The dataset is based on data and water samples collected by surface underway measurements and during CTD stations from the RRS James Clark Ross. The RAGNARoCC dataset was collected to understand the size and variability of the sources and sinks of greenhouse gases between the ocean and atmosphere in the North Atlantic Ocean. The dataset was produced by various members of the RAGNARoCC project consortium. Dr. Brian King was the cruise principal investigator for JR302. The data are made available by the British Oceanographic Data Centre, with relevant data also contributing to community research portals such as http://www.socat.info/. The dataset currently includes some of the data from cruise JR302, but is expected to include additional data from JR302. Additional data is also expected from the Porcupine Abyssal Plain Sustained Observatory (PAP-SO) mooring; the Voluntary Observing Ship (VOS) MV Benguela Stream; data from a Bay of Biscay Ferry-box route; and the RRS Discovery cruise DY040.
