Multiple sites covering the North Atlantic

Alkalinity, acidity and pH of the water column; Sea level; Vertical velocity of the water column (currents); Partial pressure (pCO2) and fugacity (fCO2) of carbon dioxide in the water column; Total dissolved inorganic carbon (TCO2) concentration in the water column; Salinity of the water column; Temperature of the water column; Dissolved oxygen parameters in the water column; Horizontal velocity of the water column (currents)

Sea level recorders; inverted echosounders; current profilers; salinity sensor; pH sensors; inorganic carbon analysers; CTD; discrete water samplers; current meters; water temperature sensor; dissolved gas sensors

The RAPID-AMOC (Rapid Climate Change - Atlantic Meridional Overturning Circulation) data set consists of pressure, current velocities, temperature, salinity, density, oxygen, alkalinity, pH, PCO2 and inorganic carbon time series. Measurements are collected by moored instruments deployed in arrays across the Atlantic at approximately 26.5N for the Monitoring the Atlantic Meridional Overturning Circulation at 26.5N (MOC) project and the Atlantic BiogeoChemical Fluxes (ABC Fluxes) project. The data set also consists of conductivity- temperature-depth (CTD) profiles, and ships' underway monitoring system meteorology and surface hydrography collected during the mooring deployment and servicing cruises. The RAPID-AMOC data set follows on from the original Rapid Climate Change (RAPID) Programme oceanographic dataset and the RAPID-WATCH dataset. It spans data collected from 2015 to the present and is intended to continue to collect data until approximately 2020. The main aims of the RAPID-AMOC Programme are to provide oceanographic measurements that continue the long time series of the Atlantic Meridional Overturning Circulation to be derived for use in climate change research. The MOC and ABC Fluxes projects are led by scientists at the National Oceanography Centre in Southampton.
