Science Objectives
The ANACONDAS project builds on observations made by MANTRA/PIRANA in 2001 and 2003 (RV Knorr and Seward Johnson I cruises to the same region) to address specifically 1) how carbon cycling and sequestration in the western tropical North Atlantic (WTNA) is influenced by the Amazon River through its impact on pelagic ecosystem dynamics and 2) the sensitivity of this ecosystem to anthropogenic climate change.  PIRANA revealed the importance of both riverine and atmospheric inputs for driving the high productivity of the WTNA through N2-fixation, and demonstrated the significance of the region to basin-wide biogeochemistry and C cycling. ANACONDAS will now focus on what drives phytoplankton community succession through the plume, light and nutrient requirements, factors limiting productivity, and the fate of production. These components are critical to understand the role of the plume in the regional C cycle, and to predict its response to climate variability and change.       The NSF-funded ANACONDAS project will also serve as a platform for additional measurements  supported by the Gordon and Betty Moore Foundation's Marine Microbiology Initiative.  ROCA (River-Ocean Continuum of the Amazon) brings additional focus on marine microbial community structure and activities, along with high-resolution measurements of organic matter along the river-ocean continuum.
Science Activities
Water Column Characterization (hydrographic sampling with CTD/Rosette): Nutrient (NO2, NO2+NO3, PO4, SiO4) concentrations Chlorophyll a and pigments concentrations Inorganic carbon (discrete DIC, ALK, underway pCO2) Organic carbon, nitrogen, phosphorus Phytoplankton and Diazotroph Abundance (using rosette and also small nets to collect) Carbon and Nitrogen Fixation by plankton Kinetic and Physiological Measurements of phytoplankton  Stable Isotopic Measurements of particulate material Microbial heterotrophy Microbial community structure and gene expression Organic carbon and biomarker characterization MOCNESS tows for zooplankton Zooplankton collection for abundance and biomass Zooplankton grazing and POC flux measurements Multicorer for deep sea sediment analyses Solid phase analysis Pore water chemistry Isotopic composition (Pb, Th, C) Other instrumentation over the side: FRRF - fast rate repetition fluorometer to measure phytoplankton physiology Optics Cage - a suite of optical sensors designed to characterize the light and fluorescence field Spectrial radiometer - also used to characterize the light field and link to satellite measurements The in-water light field will be characterized with a free-falling 14 channel spectroradiometer  Two “Carbon Explorers” – autonomous Sounding Oceanographic Lagrangian Observer profilers  Sediment Trap Studies (using 48h deployments of floating Particle Interceptor Traps; PITs) Surface water pumps - directly bring large volumes of surface water to the deck of the ship for processing.
