Wyville Thomson Ridge Acoustic Doppler Current Profiler (ADCP) Mooring


The Wyville Thomson Ridge is an area of the North Atlantic Ocean floor running in a south easterly direction from the Faroe Bank to the Scottish continental shelf. The most eastern pathway across the Wyville Thomson Ridge marks a noteable boundary between cold and warm deep water at the southern edge of the Faroe-Shetland Channel. To enable monitoring of transport across this region the Scottish Association for Marine Science (SAMS) deployed a succession of Acoustic Doppler Current Profiler (ADCP) moorings (occasionally with auxilliary instrumentation) in the region between 2003 and 2013. These moorings were situated approximately 1.2 km north-west of the formal Faroe end of the Fair Isle-Munken (FIM) line (at approximately 60.2°N, 8.9°W) and constitute part of a larger long term monitoring programme studying the nature of flow across the ridge, and the causes of its variability.
