Descripción: Eighteen year (1985-2002) sea surface temperature (SST) data are used to study the intraseasonal variability of the Patagonian shelf break front (SBF) in the SW South Atlantic Ocean between 39° and 44°S. The cross-shelf break SST gradients reveal distinct, previously undocumented thermal fronts located both, offshore and inshore of the SBF. Throughout the year the main SBF, identified as a band of negative SST gradient maxima (relatively strong offshore temperature decrease), forms a persistent feature located closed to the 200 m isobath, while two distinct negative gradient maxima are located inshore and offshore of this location. Daily SST images reveal the presence of three branches of cold waters whose edges delineate the above mentioned fronts. The two offshore branches closely follow lines of constant potential vorticity (f/h) and appear to be associated with the Malvinas Current, while a third branch, located further onshore, is not steered by the bottom topography. South of 40°S the onshore branch forms a quasi permanent front parallel to the SBF. Copyright 2008 by the American Geophysical Union.

Descripción: In this work, the modeling of plate tectonic processes associated with crustal deformation through a numerical framework for non-collisional Andean type orogens is presented. The main objectives of the numerical framework are to develop a numerical model in order to represent large-scale deformation in Andean type subduction zones, to include appropriate physical and mathematical laws that describe the behavior of the lithosphere, to model surface erosion taking into account dominant winds direction and the synorogenic topography of the orogen as the crustal erosion caused by friction between the subducting and the overriding plate and to include isostatic compensation behavior taking into account flexural rigidity. © 2005 Asociación Geológica Argentina.
