Horizontal profiles of longwave and shortwave radiation components over sea ice near Barrow, Alaska during the 2011 melt

An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.

A fronteira pampeana como local de resistência nos contos de Sergio Faraco

El precario desarrollo urbano de las ciudades periféricas de América del Sur es hasta hoy evidente para cualquier viajante que recorra el pampa gaucho brasileño y percibe la pobreza y la existencia miserable del gaucho, que resiste y lucha por su sobrevivencia en paisajes de conflicto constante. El objetivo de este trabajo es analizar cuatro cuentos del escritor brasileño Sergio Faraco, para intentar comprender como el contexto histórico de violencia y autoritarismo en la frontera sur de Brasil influenció la sociedad y el comportamiento de las personas que viven en esta región, y como la relación con la frontera interfiere en sus conceptos de vida y muerte. Para este análisis, trabajaremos con los conceptos de "entrelugar" y frontera desde la perspectiva de autores como Silviano Santiago, Eduardo Coutinho, Angel Rama y Simon Schwartzman. Pensar en fronteras significa entender los distintos modos de resistir en la vida y distintas sensibilidades. En el análisis de estos cuentos, lo que sobresale es la condición de miseria cultural y económica de los protagonistas que, ignorantes de su condición, se vuelven víctimas de un sistema autoritario no posible de contestar y, sobretodo, de lo cual no se puede escapar
