Circulation and Cross-Shelf Exchanges in the Northern Shelf Region of the Southwestern Atlantic: Kinematics
(Blackwell Publishing, 2021-04)
A high-resolution ocean model is used to characterize the circulation and cross-shelf exchanges in the Brazilian/Uruguayan portion of the southwestern Atlantic shelf. Cross-shelf exchanges are strongly modulated by the ...
Circulation and cross-shelf exchanges in the Malvinas Islands Shelf region
(Pergamon-Elsevier Science Ltd, 2021-11)
The Malvinas Islands Shelf (MIS) encompasses one of the most productive portions of the southwestern Atlantic. Large phytoplankton blooms, which constitute the base of the marine food web, emerge from the northern sector ...
Wind modulation of upwelling at the shelf-break front off Patagonia: Observational evidence
(American Geophysical Union, 2017-03)
The South-Atlantic Patagonian shelf is the largest chlorophyll-a (Chl-a) hot spot in Southern Ocean color images. While a persistent 1500 km long band of high Chl-a along the shelf-break front (SBF) is indicative of ...
The Salinity Signature of the Cross-Shelf Exchanges in the Southwestern Atlantic Ocean: Numerical Simulations
(American Geophysical Union, 2014-10)
A high-resolution model is used to characterize the dominant patterns of sea surface salinity (SSS) variability generated by the freshwater discharges of the Rio de la Plata (RdlP) and the Patos/Mirim Lagoon in the ...
Front-Eddy Influence on Water Column Properties, Phytoplankton Community Structure, and Cross-Shelf Exchange of Diatom Taxa in the Shelf-Slope Area off Concepcion (approximate to 36-37 degrees S)
(2017)
In eastern boundary current systems (EBCSs), submesoscale to mesocale variability contributes to cross-shore exchanges of water properties, nutrients, and plankton. Data from a short-term summer survey and satellite time ...
Variability of the subtropical shelf front off eastern South America: Winter 2003 and summer 2004
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Hydrographic data collected during surveys carried out in austral winter 2003 and summer 2004 are used to analyze the distributions of temperature (T) and salinity (S) over the continental shelf and slope of eastern South ...
Circulation and Hydrography in the western South Atlantic shelf and export to the deep adjacent ocean - 30 to 40S
(Wiley Blackwell Publishing, Inc, 2020-10)
High sea surface chlorophyll concentration on the Argentine Continental Shelf frequently extends to the deep ocean in the vicinity of the Brazil/Malvinas Confluence (BMC). The offshore transport of shelf waters likely plays ...
The influence of the Brazil and Malvinas Currents on the Southwestern Atlantic Shelf Circulation
(Copernicus Publications, 2010-11)
The oceanic circulation over the southwestern Atlantic shelf is influenced by large tidal amplitudes, substantial freshwater discharges, high wind speeds and – most importantly – by its proximity to two of the largest ...
Dynamical analysis of the oceanic circulation in the Gulf of San Jorge, Argentina
(Elsevier Science, 2020-03)
This study identifies the dynamical mechanisms driving seasonal variations in oceanic circulation and water mass characteristics of the Gulf of San Jorge (GSJ) and its exchanges with the Patagonian Shelf (PS). A suite of ...
The salinity signature of the cross-shelf exchanges in the Southwestern Atlantic Ocean: Satellite observations
(Wiley, 2014-10)
Satellite-derived sea surface salinity (SSS) data from Aquarius and SMOS are used to study the shelf-open ocean exchanges in the western South Atlantic near 35°S. Away from the tropics, these exchanges cause the largest ...
