Abstract/Summary

This report describes scientific activities on RRS Discovery cruise 332, “Arctic Gateway”, in the vicinity of WOCE hydrographic section AR7 between Canada, Greenland and Scotland during late summer 2008. Hydrographic work comprised 74 CTD/LADCP stations and one tow of the Moving Vessel Profiler. Water samples were captured for on-board measurement of salinity, dissolved oxygen, inorganic nutrients, calcite, particulate organic carbon and chlorophyll. Samples were also captured for storage for later on-shore analysis of oxygen isotope fraction, chlorofluorocarbons, sulphur hexafluoride and alkalinity / total carbon dioxide. Continuous underway measurements comprised: navigation; currents, using vesselmounted ADCPs (75 and 150 kHz); meteorology; sea surface temperature and salinity; and bathymetry. Mooring operations comprised the recovery of two current meter moorings off Cape Farewell; two other moorings were deemed lost; an instrument from a fifth mooring, not recovered at the time, was later found intact in west Scotland. Additionally, a party from the Royal NIOZ were engaged in a programme of recovery and redeployment of Dutch moorings. UK funding for D332 was provided by the Natural Environment Research Council under its Oceans2025 programme. KEYWORDS
