The ability of poetry – on the basis of its generic capability to bring together playfulness and awareness, an anticipated future (Ahnung) and the present – has had consequences for the history of German poetry insofar as poetry could function as a seismograph of tectonic shifts in times of societal crisis. Such was the case in the 1980s, when the East German state entered a phase of agony and there was ever more apparent disquiet in society. Multiple moments of consolidation shaped the poetry of the GDR which ought to be investigated for its epistemological potential: first, the return of political “poems for the times” (Zeitgedichte) in satirical diagnoses, second, poetic anticipation in accumulated collections of surreal visual constructs in poetry and the emphasis of grotesque effects, third, the exorbitant adventure to bring to life a space of thought and language beyond authoritarian surveillance – that is, the ambition to free the diffuse, the Proteus-esque, the marginalized, and the secretive from ossified discourse structures. A fourth tendency further resides in the historical-philosophically grounded self-determination of position and reassurance (Standortbestimmung und Vergewisserung) in poetry. Repeatedly these are bound to decided rejections of every kind of teleological progress, at times with apocalyptic scenarios. Premonition and anticipated knowledge intertwine when, for example, Volker Braun foresees the fall of the Berlin Wall in a poem written in 1988.
A satellite-based climatology of wind-induced surface temperature anomalies for the Antarctic
(2019)
It is well-known that katabatic winds can be detected as warm signatures in the surface temperature over the slopes of the Antarctic ice sheets. For appropriate synoptic forcing and/or topographic channeling, katabatic surges occur, which result in warm signatures also over adjacent ice shelves. Moderate Resolution Imaging Spectroradiometer (MODIS) ice surface temperature (IST) data are used to detect warm signatures over the Antarctic for the winter periods 2002–2017. In addition, high-resolution (5 km) regional climate model data is used for the years of 2002 to 2016. We present a case study and a climatology of wind-induced IST anomalies for the Ross Ice Shelf and the eastern Weddell Sea. The IST anomaly distributions show maxima around 10–15K for the slopes, but values of more than 25K are also found. Katabatic surges represent a strong climatological signal with a mean warm anomaly of more than 5K on more than 120 days per winter for the Byrd Glacier and the Nimrod Glacier on the Ross Ice Shelf. The mean anomaly for the Brunt Ice Shelf is weaker, and exceeds 5K on about 70 days per winter. Model simulations of the IST are compared to the MODIS IST, and show a very good agreement. The model data show that the near-surface stability is a better measure for the response to the wind than the IST itself.
This literature review was conducted to identify important wetlands in the Greater Accra Region and to illustrate dominant research trends, prevailing perspectives and corresponding research gaps. Six wetlands systems were identified as most significant lagoon systems, namely the Densu Delta, Sakumo, Muni-Pomadze, Keta, Korle and Songor Lagoons. Research foci for each of the respective wetlands were extrapolated and summarized in a category system. The frequency of different categories illustrates that natural science’s perspectives dominate, as most of Accra’s lagoons have been studied with regard to their ecological, physical and chemical properties. The development of research interest over time and focus on ecological baseline conditions are related to the designation of Ramsar Sites and orientation of national policies towards environmental protection. A research gap was identified, as studies link their findings to human activities but neglect the connection between governance variables and environmental developments. It is suggested to expand the natural science’s perspective on Accra’s wetlands to account for social and political aspects in order to develop a holistic and more sustainable management strategy.
