This project was funded by NSF Office of Polar Programs and includes colllaboration with projects separately funded by NASA Oceanbiogeochemistry Program, NOAA Antarctic Marine Living Resources (AMLR), and NOAA Global Drifter Program.
Optical data and supporting biology data submitted to NASA GSFC
Surface Ed (PAR) monitored continuously using a Biospherical ... QSR-240 quantum irradiance meter. Free-fall profiling spectral radiometer (PRR-800, Biospherical Instruments, Inc.) deployed daily at local apparent noon to determine the spectral composition of the surface and underwater light fields. A separate profiler collected profiles of chlorophyll fluorescence (Wetlabs Inc.), spectral beam transmission ( Wetlabs) and backscattering (Hydroscat, HobiLabs), and variable fluorescence (Fasttracka, Chelsea Instr.).
Drifter data submitted to NOAA AOML
Surface current drifters, provided by NOAA AOML Global Drifter program, were deployed throughout the cruise, allowing for resolution of currents and eddies through out the study region including the ACC, Southern ACC Front, and Bransfield Straight and Weddell Sea outflows.
Cruise water sample data submitted to NODC
Measurements of taxa, distribution, biomass, size distribution, photosynthetic pigments, photosynthetic rates of phytoplankton, bacteria, iron and biogeochemical dynamics in the upper water column. Estimates of rate of primary production. Measurement of particulate organic carbon and nitrogen. Measurement of inorganic macronutrients and dissolved iron. Bacteria taxa, growth rates, and abundances.
