This report describes the events that occurred during DY052, a cruise on the RRS Discovery that sailed Glasgow to Glasgow from June 7 to June 24, 2016. The main objective of the cruise was to occupy the annually repeated hydrographic section of the Extended Ellett Line (EEL). The EEL runs from the Sound of Mull via Rockall to Iceland. The EEL is is funded by NERC under the National Capability Program. More information on the history and findings of the EEL can be found at http://prj.noc.ac.uk/ExtendedEllettLine/ . This was a successful cruise with all objectives fulfilled and minimal downtime. Calibrated, processed data from DY052 will be banked with the British Oceanographic Data Centre (BODC, http://www.bodc.ac.uk). The main objectives for DY052 were: 1) Hydrographic stations 71 planned CTD stations + 1 test station. We achieved 89 CTD stations. Specific measurements: CTD + other electronic instruments + LADCP Bottle salinity Bottle oxygen Bottle nutrients (Nitrate+Nitrite, Phosphate, Silicate) Bottle carbon (alkalinity, DIC) Bottle trace metals Bottle density 2) Underway measurements towed hydrophone for any transits greater than 30 minutes meterological and oceanographic underway measurements sail by the locations of the OSNAP moorings in Rockall Trough 3) Epibenthic sled tows at “Station M” (4 tows) 4) Argo loat deployments (3 loats)
