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.

La poética de Mercé Rodoreda (1909-1983) ha permitido pensar y reflexionar acerca de las nuevas posibilidades que admite la literatura, en cuanto a la creación de climas que, mediante artificios narrativos, invitan al lector a un juego simbólico y metafórico. En él, la narradora involucra esencialmente elementos de la naturaleza, como los animales y las plantas que, a su vez, son resignificados y reiterados dentro de sus obras. Estas operaciones literarias tienen una estrecha relación con la narrativa de Franz Kafka (1883-1924) en la cual, ambos componentes: lo simbólico y lo metafórico, generan una atmósfera indeterminada a partir de la aparición de 'lo extraño'. Esta introducción del elemento extraño es la responsable directa de la creación del clima que sobrevuela las narraciones de muchos de los cuentos de Rodoreda. Ejemplo de ello son: La sala de muñecas, El río y la barca, Mi Cristina, La salamandra, El elefante, entre los cuales se incorporan temas como; la metamorfosis, lo siniestro, lo onírico, asociados a los problemas del existencialismo. Franz Kafka en varios de sus relatos construye mundos desestabilizadores y perturbadores que, mediante la configuración de una poética única, trasladan al lector al espacio lo diferente, a través de la presencia de elementos simbólicos, tal como sucede con los cuentos de Rodoreda. Dichos elementos se ligan a las reflexiones sobre la existencia humana en el devenir del mundo y de la sociedad moderna. Este vínculo entre ambos autores sólo será demostrable en la medida en que podamos inscribir los modos de recepción en una lógica diferente

Rb, Sr, Sm, Nd, U, and Pb contents and Sr, Nd, and Pb isotopic composition were determined in tholeiite and subalkaline basalts (in both whole-rock samples and individual minerals) from the Franz Josef Land Archipelago. Isotopic data obtained for the Arctic basin are similar to those for islands from the Pacific, Atlantic, and Indian oceans. The assimilation of crustal (sedimentary) rocks by primary depleted material makes isochron determination of basalt age difficult or impossible. The subalkaline basalts (basaltic andesites) were presumably formed by the metasomatic introduction of incompatible elements in tholeiitie basalts and, only partially, through crustal contamination and fractional crystallization.
