Variability of OCean Ecosystems around South-America (VOCES)
The overall goal of this project is to assess the impact of climate variability —both natural and anthropogenic—on the Humboldt, Patagonia, and South Brazil Large Marine Ecosystems. These ecosystems are among the most productive of the southern hemisphere, sustain more than 20% of the global fish catch, host unique biodiversity and absorb CO2 at rates comparable with the most significant uptake regions in the World Ocean.
Export of shelf waters along the Subtropical Shelf Front: A one way ticket?
Our previous work leads us to believe that the STSF is a preferential site for the detrainment of shelf waters onto the deep ocean. Our studies indicate that deep-ocean waters entrained along the Patagonian and Brazilian shelves are funneled towards this front where they are fluxed offshore. In this CRN2 follow-up we propose to test this hypothesis and some of its biological and biogeochemical implications which may globally significant. PI: Alberto R.

South Atlantic Circulation and Salinity: An Integrated Observational and Modeling Investigation
PI: Alberto R. Piola, SHN/UBA/CONICET/Instituto Franco-Argentino sobre Estudios de Clima y sus Impactos, Financed by Ministerio de Ciencia y Tecnología, Argentina This project seeks to assess the degree to which Aquarius SSS (sea surface salinity) data can be used to improve our understanding of the variability of the South Atlantic circulation. Our scientific goal is to determine the dominant modes of large-scale variability of the South Atlantic circulation and their impacts on the meridional overturning circulation and on the currents and thermohaline structure of the eastern shelf of South America. To achieve this goal we propose a US-Argentina collaborative program whose specific objectives are: 1) determine the dominant modes of variability of the South Atlantic circulation and thermohaline structure along with their relation to interocean fluxes, atmospheric forcing, and internal ocean processes; 2) Assess the relation between SSS and other modes of oceanic (e.g., SSH, SST) and atmospheric variability (e.g., E-P, wind-stress curl, etc) and determine the utility and limitations of Aquarius data; 3) characterize the spatial and temporal variability of the southwestern Atlantic shelf circulation and determine the dynamical mechanisms controlling its interactions with the deep-ocean circulation; 4) assess the utility of Aquarius SSS data to improve the skill of modeling products. To address these objectives we propose a modeling and observational project that will not be limited to the analysis of extant data sets but includes the development of new models and the acquisition of new observations.
