25 Years of Polarstern Hydrography (1982-2007)

Since her commissioning in 1982 RV Polarstern has been operating in the Arctic and Antarctic to carry out scientific research. Between November and March she usually sails to and around the waters of the Antarctic, while the northern summer months are spent in Arctic waters. But also during transits between Bremerhaven and South Africa or South America long-term observations have regularly been performed by using a.o. XBT (Expendable Bathythermograph), CTD (Conductivity, Temperature, Depth), and Thermosalinograph which are standard instruments to carry out hydrographic measurements and are part of the standard instrumentation on board Polarstern. This report presents XBT and CTD profiles as well as sea surface temperature and salinity data recorded with Thermosalinograph during Polarstern cruises. In the framework of physical oceanographic studies the measurements were performed as part of international projects (e.g. like WOCE) or to support multidisciplinary studies.

Efectos psicosociales y sociopolíticos de la Guerra de Malvinas en las provincias de Chaco y Corrientes, 1982 →. 16H241

El proyecto plantea un estudio psicosocial y antropológico del impacto que tuvo la Guerra de Malvinas sobre la política y la identidad de la población de las provincias de Chaco y Corrientes, región desde la que se movilizó un nutrido contingente de soldados hacia el frente de guerra. El periodo a investigar abarca desde el acontecimiento en 1982 hasta nuestros días y pone la mirada sobre los protagonistas del momento: soldados, gobernantes, dirigentes y activistas sociales, y sobre las generaciones posteriores al hecho que lo conocen a partir de la memoria transmitida. El tema es abordado a través de la investigación documental y de entrevistas en profundidad. Constituye una etapa en el desarrollo de la línea de investigación sobre la Guerra de Malvinas en la región del nordeste argentino que se inició en el año 2004, por lo cual contamos con resultados que nos permiten reorientar la investigación hacia distintos aspectos de los efectos del acontecimiento en la sociedad. Este avance nos permite un mayor acercamiento con las organizaciones de ex combatientes que desarrollan su actividad en ambas provincias.

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.
