RRS Discovery Cruise 245, 27 Jan-20 Feb 2000. A hydrographic section from Scotland to Iceland

The report describes the RRS Discovery Cruise 245, designed as a repeat of the hydrographic section that includes the Ellett line from Scotland to Rockall, and the SOC extension to Iceland. The section consisted of stations for CTD, LADCP, chemistry (nutrients, oxygen) and biology (chlorophyll). Continuous measurements of high precision position and heading navigation data were made, also of surface currents (VM-ADCP), depth, surface temperature and salinity, surface nutrients and high-quality meteorological measurements. The cruise objectives also included recovering two deep ocean and two shelf current meter moorings, and collecting shallow sediment cores in the Muck Deep, a shelf depression. The cruise was severely hit by bad weather and as a consequence not all the scientific objectives were achieved.
