A programme to monitor the strength and nature of the Atlantic Meridional Overturning Circulation, primarily to assess its significance in determining the climate of northern Europe. Because of the importance of oceanic heat transport between latitudes 25–35° N, a major feature of the programme is the establishment of a series of moorings across the Atlantic at 26.5° N to determine factors such as temperature, salinity, pressure, and currents. These provide continuous monitoring of the transatlantic pressure gradient. In addition, the voltages induced on submarine cables across the Florida Strait by charged particles within the moving sea-water enable the strength of the Florida Current to be determined on a continuous basis.
