Cruise Inventory Information
| Long name | RRS Charles Darwin (74AB) cruise CD61 |
|---|---|
| Short name | CD61 |
| Objectives and Narrative |
A) To determine rates of coccolithophore photosynthesis and calcification in relation to the stage of development and species composition of the annual bloom in the S. Iceland basin.
B) To measure water column primary production and specific phytoplankton growth rates within and outside the coccolithophore bloom, using fractionation techniques to estimate the relative importance of different size groups of autotrophic cells. C) To measure rates of grazing on coccolithophores by herbivorous meso- and micro-plankton with special attention to grazing efficiency with respect to the size and density of coccolithophore cells and to the nature (composition, pellet size anddensity etc.) of faecal material. D) To measure sedimentation rates and particle characteristics throughout the deep water column, both within and outside a coccolithophore bloom, using drifting sediment traps, stand-alone pumps, camera systems and large-volume water bottles. E) To identify elements of the protozoan community involved in coccolithophore aggregate remineralisation, and to determine the relative importance of bacteria and protozoa on the degradation and transformation of aggregates. F) To determine the primary production rates of alkenones and other primary produced biomarkers in relation to coccolithophore production, and to determine the export flux of biomarkers relative to POC flux, and their relative loss through the water column. |
