PurposeResearch
ObjectivesFluxes in the contemporary system (Lagrangian Study) Iceland Basin.
The aim of this cruise was to study the time-varying fluxes of carbon mediated by natural communities of the surface mixed layer associated with the drift station. The cruise aim was divided into a series of objectives which addressed:
1. The in-situ production and utilisation of CO2, O2 and nutrients.
2. The assimilation rates of inorganic carbon and nitrogen by different size fractions of phytoplankton as controlled by light, nutrients and trace metals.
3. Primary production and community respiration by high precision O2 measurements.
4. Cyanobacteria and their expression of gene activity.
5. Bacterial biomass and productivity and its relationship to primary production.
6. Phytoplankton biomass and taxonomic composition by microscopy, high performance liquid chromatography (HPLC) and analytical flow cytometry (AFC).
7. Micro- and meso-zooplankton biomass and their herbivorous impact on phytoplankton.
8. The vertical distribution of inorganic and organic 'biomarkers', including N-15 isotope, Po-210, Pb-210 and Th-234 radionuclides, pigments, lignins, POC & PON using Stand-Alone Pumps (SAPS).
9. "Level 1" core parameters as part of the JGOFS/BOFS Atlantic programme.
