The data set comprises current velocity, hydrographic pressure and sea temperature measurements from the Scottish continental slope between August 1982 and June 1983. The instrument deployments, mainly current meter moorings, were made along a set of lines defined A-G across the Scottish continental slope (51 N - 63 N, 0 - 15 W). Current meters recorded horizontal currents, temperature and pressure, while six bottom-mounted pressure gauges were deployed at either end of each line. Four temporary tide gauges were also installed from Sligo (Ireland) to Shetland. The Continental Slope Experiment (CONSLEX) was designed to study water movements across the Scottish continental slope. CONSLEX was a collaborative exercise between the Institute of Oceanographic Sciences Wormley Laboratory (IOSW) and the Institute of Oceanographic Sciences Bidston Laboratory (IOSB) now collectively known as the National Oceanography Centre (NOC); the Scottish Marine Biological Association (SMBA), now known as the Scottish Marine Institute based at the Dunstaffnage Marine Laboratory (DML); the Scottish Office Agriculture and Fisheries Department (SOAFD), now known as Marine Scotland Aberdeen Marine Laboratory; and the Ministry for Agriculture, Fisheries and Food Lowestoft Laboratory (MAFF), now known as the Centre for Environment, Fisheries and Aquaculture Science Lowestoft Laboratory (CEFAS). The data are held at the British Oceanographic Data Centre (BODC).
