McLane Remote Access Samplers (RAS) are now part of the UK Natural Environment Research Council (NERC)-funded Rapid Climate Change Programme (RAPID) moorings, with RAS frames added to moorings placed offshore of Africa, the Bahamas and at the mid-Atlantic ridge.
The Atlantic Biogeochemical (ABC) Fluxes project – led by scientists from National Oceanography Centre Southampton (NOCS) – customized the RAS frames to hold additional pH, pCO2 and oxygen sensors.
The sampler and sensor suites will aid in creating high frequency time-series of the biogeochemical variability of the transatlantic upper ocean, and at depth in the western boundary. Together, these will enhance the ability to estimate the transport of total natural and anthropogenic carbon and inorganic nutrients across the subtropical Atlantic.
The project is an add-on to the RAPID mooring array across the Atlantic at 26.5°N. These moorings have been monitoring the Atlantic Meridional Overturning Circulation (MOC) since 2004. Monitoring at this location will continue at least until 2020, with the ABC Fluxes project building on the infrastructure of the existing array to provide new biogeochemical measurements.
