Summary of measurements |
- -Measurement of temperature, salinity, oxygen over the entire water column; optical profiles and UV-B penetration.
-Measurements of nutrients: nitrates, nitrites, phosphates, silicates and ammonium; Studying high frequency variability in the surface layer. -Study of the carbonate system: measurements of CO2 fugacity in surface waters, total alkalinity and inorganic carbon in the water column. -Primary production and biogenic silica production and standing stock; population make-up and distribution of phytoplankton biomasses; pigment distribution. -Parametrization of autotrophic production: flow cytometry; ETS, carboxylase activity, glycolic acid production, biochemical make-up, isotope ratios. -Nitrogen assimilation by phytoplankton; defining the ingestive activity of protozooplankton. -Heavy metal concentrations; Dissolved and particulate iron dynamics; profiles of particulate CHN; Isotope and molecular tracers; video recording of vertical particle profiles. -Vertical distribution of bacterial activity; bacterial transformation and mineralization of organic matter. -Measuring sedimentation rates using drifting sediment traps; vertical export flux of DMSP. -Composition of mesozooplankton, micronecton and hyponeuston populations; ingestive, respiratory and intestinal transit activity; vertical profiles of macroplakcton by video.
