AbstractField observations during a journey through the arid regions of the South American Andes in June-July 1969 are evaluated in conjunction with available air photographs and reports from adjacent regions of the High Andes. Results indicate an increase of the Pleistocene snow-line depression in the western Cordillera from about 700 m at lat. 12° S. to more than 1 500 m at lat. 30° S. The Pleistocene snow-line depression decreases from the Pacific to the Atlantic side of the Andes, but particularly strongly so on the poleward fringe of the arid region. From this geomorphic evidence it is suggested that the atmospheric circulation during the glacial period was characterized by an Equatorward displacement of the boundary between tropical easterlies and temperate-latitude westerlies.

Abstract. The variability of the simulated hydro-climatology of the WaterGAP Global Hydrology Model (WGHM) is analysed. Main object of this study is the ENSO-driven variability of the water storage of South America. The horizontal model resolution amounts to 0.5 degree and it is forced with monthly climate variables for 1961-1995 of the Tyndall Centre Climate Research Unit dataset (CRU TS 2.0) as a representation of the observed climate state. Secondly, the model is also forced by the model output of a global circulation model, the ECHAM4-T42 GCM. This model itself is driven by observed monthly means of the global Sea Surface Temperatures (SST) and the sea ice coverage for the period of 1903 to 1994 (GISST). Thus, the climate model and the hydrological model represent a realistic simulated realisation of the hydro-climatologic state of the last century. Since four simulations of the ECHAM4 model with the same forcing, but with different initial conditions are carried out, an analysis of variance (ANOVA) gives an impression of the impact of the varying SST on the hydro-climatology, because the variance can be separated into a SST-explained and a model internal variability (noise). Also regional multivariate analyses, like Empirical Orthogonal Functions (EOF) and Canonical Correlation Analysis (CCA) provide information of the complex time-space variability. In particular the Amazon region and the South of Brazil are significantly influenced by the ENSO-variability, but also the Pacific coastal areas of Ecuador and Peru are affected. Additionally, different ENSO-indices, based on SST anomalies (e.g. NINO3.4, NINO1+2), and its influence on the South American hydro-climatology are analysed. Especially, the Pacific coast regions of Ecuador, Peru and Chile show a very different behaviour dependant on those indices.

ABSTRACT The South American Funds National Exchequer was established in 1818 to contribute to the consolidation of the public debt of Buenos Aires. It was the first financial innovation since the revolutionary outbreak in Buenos Aires, and its failure allowed the authorities to understand the limits of the fiscal and financial commitment they proposed by means of that institution. Its suppression, in 1821, offered an antecedent to develop a deep reform of the financial institutional matrix of Buenos Aires, based on the Public Credit office, the Amortization Exchequer and the Bank of Buenos Aires. The South American Funds National Exchequer was, thus, the first movement in the negotiation on the terms of the financial commitment assumed by the nascent State. This paper analyzes the 973 accounting entries of the institution, providing an interpretation of that failure and its importance for the course of public finances in Buenos Aires.

ResumenLa prensa sudamericana, en particular la de Buenos Aires, tuvo un amplio y heterogéneo desarrollo en la segunda mitad del siglo XIX, resultado y expresión de diversas orientaciones políticas, caracterizándose por ser una prensa de opinión, doctrinaria, de trinchera y cada vez más informativa en virtud de los acontecimientos que marcaron el desarrollo de las sociedades latinoamericanas. Uno de esos eventos trascendentales a nivel regional fue la Guerra del Pacífico (1879-1883) que enfrentó a Chile contra la alianza de Perú y Bolivia. Este conflicto adquirió una importante dimensión internacional y generó un permanente interés informativo en la prensa argentina. Por consiguiente, el artículo tiene como objetivo caracterizar la actitud discursiva que adoptó parte de la prensa de Buenos Aires al momento de analizar y juzgar la conducta de Chile durante la Guerra del Pacífico. Planteamos la existencia de un “negativo imaginario internacional” que sematerializó en la formulación de un discurso periodístico que asignó a Chile y a los chilenos una conducta bélica “agresiva, expansionista y opuestaa los principios de la civilización”, la cual amenazaría potencialmente losintereses nacionales argentinos en el contexto de las disputas limítrofes entre ambos países.Palabras clave: Guerra del Pacífico; Argentina; Prensa; Opinión Pública“The american Prussia”: Argentinian press and international imaginary in Chile during the War of the Pacific (1879-1881)AbstractThe South American press, particularly in Buenos Aires, had a large and heterogeneous development in the second half of the Nineteenth Century, as a result and expression of different political persuasions, characterized by being a press of opinion, doctrinaire, of trench and increasingly informative under the events that marked the development of Latin American societies. One of those transcendent events at the regional level was the War of the Pacific (1879-1883) where Chile fought against Peru and Bolivia alliance. That conflict acquired an important international dimension and created a permanent information interest in Argentina press. Therefore, the article aims to characterize the discursive attitude adopted by part of the press of Buenos Aires at the time to analyze and judge the Chilean performance during the War of the Pacific. We propose the existence of an “international negative imaginary”, materialized in the formulation of a journalistic discourse that assigned to Chile and Chileans a war conduct that was “aggressive, expansionistand opposed to the principles of civilization”, which potentially threaten the national Argentine interests in the context of border disputes betweenthe two countries.Keywords: Pacific War; Argentina; press; public opinion“A Prussia americana”: imprensa argentina e imaginário internacional do Chile durante a Guerra do Pacífico (1879-1881)ResumoA imprensa sul-americana, particularmente Buenos Aires, teve um amplo e heterogêneo desenvolvimento na segunda meta de do século XIX, resultado e expressão das diversas orientações políticas, com a característica de ser uma imprensa de opinião, doutrinária e de trincheira, cada vez mais informativa em virtude dos acontecimentos que marcaram o desenvolvimento das sociedades latino-americanas.

GNSS observations constitute the main tool to reveal Earth’s crustal deformations in order to improve the identification of geological hazards. The Ecuadorian Andes were formed by Nazca Plate subduction below the Pacific margin of the South American Plate. Active tectonic-related deformation continues to present, and it is constrained by 135 GPS stations of the RENAGE and REGME deployed by the IGM in Ecuador (1995.4–2011.0). They show a regional ENE displacement, increasing towards the N, of the deformed North Andean Sliver in respect to the South American Plate and Inca Sliver relatively stable areas. The heterogeneous displacements towards the NNE of the North Andean Sliver are interpreted as consequences of the coupling of the Carnegie Ridge in the subduction zone. The Dolores–Guayaquil megashear constitutes its southeastern boundary and includes the dextral to normal transfer Pallatanga fault, that develops the Guayaquil Gulf. This fault extends northeastward along the central part of the Cordillera Real, in relay with the reverse dextral Cosanga–Chingual fault and finally followed by the reverse dextral Sub-Andean fault zone. While the Ecuadorian margin and Andes is affected by ENE–WSW shortening, the easternmost Manabí Basin located in between the Cordillera Costanera and the Cordillera Occidental of the Andes, underwent moderate ENE–WSW extension and constitutes an active fore-arc basin of the Nazca plate subduction. The integration of the GPS and seismic data evidences that highest rates of deformation and the highest tectonic hazards in Ecuador are linked: to the subduction zone located in the coastal area; to the Pallatanga transfer fault; and to the Eastern Andes Sub-Andean faults.
