Fatty acids and intact polar lipids of laminated microbial sediments from St. Peter Ording, German Wadden Sea

Hidden for the untrained eye through a thin layer of sand, laminated microbial sediments occur in supratidal beaches along the North Sea coast. The inhabiting microbial communities organize themselves in response to vertical gradients of light, oxygen or sulfur compounds. We performed a fine-scale investigation on the vertical zonation of the microbial communities using a lipid biomarker approach, and assessed the biogeochemical processes using a combination of microsensor measurements and a 13C-labeling experiment. Lipid biomarker fingerprinting showed the overarching importance of cyanobacteria and diatoms in these systems, and heterocyst glycolipids revealed the presence of diazotrophic cyanobacteria even in 9 to 20 mm depth. High abundance of ornithine lipids (OL) throughout the system may derive from sulfate reducing bacteria, while a characteristic OL profile between 5 and 8 mm may indicate presence of purple non-sulfur bacteria. The fate of 13C-labeled bicarbonate was followed by experimentally investigating the uptake into microbial lipids, revealing an overarching importance of cyanobacteria for carbon fixation. However, in deeper layers, uptake into purple sulfur bacteria was evident, and a close microbial coupling could be shown by uptake of label into lipids of sulfate reducing bacteria in the deepest layer. Microsensor measurements in sediment cores collected at a later time point revealed the same general pattern as the biomarker analysis and the labeling experiments. Oxygen and pH-microsensor profiles showed active photosynthesis in the top layer. The sulfide that diffuses from deeper down and decreases just below the layer of active oxygenic photosynthesis indicates the presence of sulfur bacteria, like anoxygenic phototrophs that use sulfide instead of water for photosynthesis.

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.

"Un saludo a los fantasmas del futuro" o cómo leer la temporalidad en Amadeus de Peter Shaffer

En la última edición de Amadeus publicada con modificaciones de su autor (2001), Peter Shaffer introduce una periodización del proceso escritural de esta obra. Este gesto instituye un orden de lectura que busca organizar una historia de los conflictos entre Mozart y Salieri, entendiendo el término "historia" en un sentido teleológico. No obstante, desde la crítica genética resulta posible leer otra temporalidad en Amadeus, una temporalidad marcada por lo discontinuo y el anacronismo. Desde esta perspectiva se vuelve posible construir sistemas o ejes de lectura que crucen en forma transversal y rizomática la clave de lectura propuesta por Shaffer. En este trabajo analizaremos la temporalidad en Amadeus y para ello tendremos en cuenta: la propuesta de lectura del propio Shaffer; la temporalidad de los materia¬les de génesis, la condición de la obra como ficcionalización de hechos históricos; la consecuente presencia de elementos anacrónicos en la escritura; y el rol de la intertextualidad en la génesis de Amadeus, afectando tanto a esta pieza como a las obras-enunciados con las que entra en polémica

La genética textual como lectura comparatista : El caso de la génesis de Amadeus, de Peter Shaffer

En este trabajo se presentan algunas reflexiones sobre los aportes de la genética textual o crítica genética (Lois, 2001; Goldchluk, 2005; 2009) al comparatismo. Dado que este enfoque propone un trabajo con el proceso de escritura, presupone la comparación entre diferentes estadios textuales; la obra es la suma de los diferentes estadios textuales y momentos de archivación, no sólo el estadio édito para esta perspectiva. El modo de lectura que puede desprenderse de este enfoque permite encontrar en una obra diferentes núcleos de análisis que pueden leerse de modo transversal en diferentes instancias textuales, por lo cual se puede efectuar una lectura que denominaremos «constelada¼. ;Para abordar estas ideas, recurriremos a observaciones surgidas a partir del proyecto de licenciatura que se centra en el estudio de la génesis textual de la obra Amadeus, del dramaturgo inglés Peter Shaffer.
