This 18-day trip aimed to survey a recognised North East Atlantic site called the Porcupine Abyssal plain sustained observatory (PAP-SO). It is a long running site collecting data on many essential ocean variables.
The RRS Discovery departed Southampton on the 21th June and is returning today, Sue Hartman (NOC) co-led the campaign on-board the cruise (DY103). This trip was part of the CLASS (Climate Linked Atlantic Sector Science) project funding underpinning observations, and reached the Porcupine Abyssal Plain sustained observatory (PAP-SO) site in the North East Atlantic.
According to Sue’s publication at PAP’s blog, “The trip has been successful and we recovered and deployed various autonomous systems and collected many samples. A full set of data is sent from the buoy, via a satellite link. Analysing this ‘near real time’ data, and looking at the collected samples, will keep us busy for a while. The sediment trap time series itself now spans thirty years and will be used to look at both short and long term variations in carbon fluxes from the surface to the ocean depths.” The co-sampling with satellite pass over is part of the work within the iFADO project.
PAP-SO is a recognised ICOS (Integrated carbon observation systems) site and is one of 11 sustained EMSO (European Multi-disciplinary Seafloor and water column observatories – ERIC) observatories, hosting the longest biogeochemical and ecosystem time series records in Europe.
