ADCP Arrays Reveal Details of Deep Overflow Plume


​​​​​​​​​Efforts to understand changes in the global climate system have put a spotlight on the deep ocean. Scientists are now focused on the water properties and volumes of confluent flows that form the deep circulation. Although this circulation is global in extent, its source waters are localized to high latitudes in each hemisphere.

For more than two decades, Nordic oceanographers have used Teledyne RDI ADCPs to monitor the volume transport of one of these deep flows through the Faroe Bank Channel (FBC) in the subpolar North Atlantic.  Recently, researchers at University of Bergen (Norway) examined how the FBC overflow characteristics change due to intense mixing and entrainment after the deep plume departs the FBC.
