PurposeResearch
ObjectivesThe cruise D354 is linked to D350, and form part of a study entitled 'Iron Biogeochemistry in the High Latitude North Atlantic'. The study is investigating the potential influence of iron availability on phytoplankton production in regions of the North Atlantic. The purpose of the cruises are to undertake measurements of dissolved and particulate iron availability, their spatial and temporal variations, and their impact on microbiology in the surface ocean.

Our specific cruise objectives are to:
1. Determine total dissolved Fe and Al (<0.2 micron) and macro-nutrient concentrations, in addition to Fe speciation, in areas of the high latitude North Atlantic Ocean.
2. Undertake on-board nutrient enrichment bioassay experiments with additions of Fe to determine the potential for Fe limitation in the Iceland and Irminger Basins.
3. Undertake phytoplankton photophysiological measurements, chlorophyll a, pigment analysis and counts of phytoplankton both within bioassays and the in situ population to determine the physiological basis and extent of Fe limitation.
4. Determine atmospheric inputs through aerosol sampling, combined with back trajectory analyses.
5. Determine Fe and nutrient fluxes (and their ratios) in particulate sedimenting material using Stand Alone Pumping Systems (SAPS) and 234Th depletions at different water depths.
6. Determine Fe and nutrient supplies to high latitude N Atlantic surface waters through diapycnal transfer, convective fluxes, and wind induced vertical and lateral advection through Ekman transfer.
7. Determine the lateral transfer of Fe and nutrients from the geostrophic circulation and horizontal eddies using a general circulation model.
8. Provide a synthesis of Fe and nutrient inputs from the atmosphere and ocean circulation for the high latitude N Atlantic.
