This was the fourth and last cruise undertaken as part of the NERC-funded consortium project (NE/C512961/1) entitled ECOMAR - Ecosystem of the Mid-Atlantic Ridge at the Sub-Polar Front and Charlie Gibbs Fracture Zone. http://www.oceanlab.abdn.ac.uk/ecomar/index.php ECOMAR forms part of the Census of Marine Life MAR-ECO project which is an international study of life in the northern mid-Atlantic Ocean with scientists from 16 nations participating in research of the waters around the mid-Atlantic Ridge from Iceland to the Azores (http://www.mar-eco.no). Depart: Wednesday, 26 May, St Johns, Newfoundland, Canada. Long term moorings were recovered at four super stations at a bottom depth of 2500m equipped with sediment traps, current meters, ADCP and sensor suites, SE - 49°01.92'N, 27°40.82'W, SW - 48°46.80'N, 28°38.43'W, NW - 53°59.33'N, 36°07.39'W and NE 54°00.05'N 34°10.58'W. Video and still images of the sea floor were obtained during 4 lander deployments and 21 ISIS ROV dives. Faunas samples were taken on 17 of these ROV dives, further samples from 13 successful megacorer casts and 4 baited traps. High definition video sea floor surveys were completed of approximately 50,000 m2 of sea floor. Arrive: Vigo, Spain, Saturday 3 July 2010.
