Göbekli Tepe is a supraregional cult center of the 10th and 9th century BC and is one of the most important and most discussed sites from the transitional period between hunter-gatherers and settled farmers. Recently this year, Göpekli Tepe has been declared as an Unesco World Heritage. The tell contains several megalithic circle systems, partly with T-pillars, which raised many speculations.

Lee Clare leads the excavations in Göbekli Tepe and reports in his lecture about the new excavations and research in Göbekli Tepe.

Alexander Gerner: Strata- Geophilosophische Notizen zu Sergio Costa

by Dr. Alexander Gerner
Center for Philosphy of Sciences of the University of Lisbon
(presentation will be held in English)

Within his talk the German philosopher and theater director Alexander Gerner takes up abstract geology as a complementary perspective: strata as a concept derived from geology and made operational in the human realms’ arts and knowledge development. He will present an atlas of friendship between philosophy, science, art and human technology by means of an observational program presented in the painting series “Strata” and other working images of the artist Sérgio Costa. The presentation will present experimental maps, illustrating an enhanced thinking of the concept „Strata: How are we able to experience long-time change?

Daniela Holst: Subsistence & resource management in the early Holocene

The profound environmental changes at the beginning of the early Holocene worldwide are accompanied by innovations in human land-use, leading to a sedentary lifestyle and domestication in some parts of the world. The talk focuses on subsistence and land-use strategies in the contemporaneous European Mesolithic. Well-preserved archives allow for high-resolution reconstructions and quantitative assessments of the processing and stockpiling of high return harvests of energy rich foods. The hazelnut-roasting camps of Duvensee in Northern Germany form a prime example of Mesolithic subsistence strategies. Their potential implications on land-use and mobility are discussed in context with new evidences. A future research project on ground stone tools will contribute to the complement of our patchy image of the Mesolithic.

Martin Theuerkauf: From guesswork to maps – recent progress in quantitative vegetation reconstruction

The talk will give an overview of the main current approaches and illustrate their strength and weaknesses in a number of examples. It will then introduce the new ROPES approach. This method does not require pollen productivity as a parameter, and so may overcome major limitations of the present methods. It is suited to extend quantitative vegetation reconstruction into new regions and pre-Holocene periods, and allows analysis of long pollen records that cover several glacial/interglacial cycles. 

By Dr. Martin Theuerkauf from the

Institute of Botany and Landscape Ecology, University of Greifswald

Vegetation reconstruction from pollen data, although dealing with counts and percentage values, has long been a mere semi-quantitative field. Pollen percentages do not directly represent past vegetation composition, because plants species produce pollen in very different amounts and with different dispersal patterns. This bias in pollen data is well known since the inception of the field 100 years ago, but correction for a long time relied on ad-hoc informed guesswork.

Today, a suite of methods is available that enable true quantitative interpretation of pollen data. The methods cover different spatial scales: REVEALS for example aims to translate pollen deposition from large lakes into regional vegetation composition. LOVE and Marco Polo reconstruct stand-scale vegetation composition using pollen data from very small sites. The extended downscaling approach and the multiple scenario approach explore vegetation patterns in landscapes using multiple pollen records.

So far these methods are still rarely applied, however, for a number of reasons. Most importantly, the underlying parameters pollen productivity and pollen dispersal require elaborate calibration and are hence so far available for some regions only.

Good Scientific Practice

Dear participants,
Please note: The meeting location has been changed to “Übungsraum 1 (Rundbau Geographie)”

Dr. Karin Boessenkool

Good scientific practice in research and scholarship is essential for the integrity of science. It sets internationally valid benchmarks for quality assurance, which enable replication and further studies by other scientists. And it provides safeguards against scientific dishonesty and fraud. Good practice, thus, nurtures trust within the scientific community and between science and society, both of which are necessary for scientific advance (Source: European Science Foundation)

This workshop is divided into two parts: the first part (02.07.2018) will introduce you to the principles of good scientific practice. An overview of your rights and responsibilities as a researcher will be presented, followed by a discussion about who sets the rules and regulations  (recommendations) for good scientific practice.

In the second part (16.07.2018) you have the opportunity to assess issues related with good/bad scientific practice in a guided group discussion on five different themes (Ideas, Data collection and storage, Data in publications, Publications and the role of co-authors, Review process).

Please refer to the recommended readings below.

The workshop will be held by Dr. Karin Boessenkool (Coordinator of the Geosciences Graduate School).

Paleolithic research in Armenia – eclectic point of view and future directions

Paleolithic research in Armenia by Dr. Ariel Malinsky-Buller, Senior Researcher at the Monrepos Archaeological Research Centre and Museum for Human Behavioural Evolution.

Armenia is situated in the Southern Caucasus at the geographical intersection of Africa and Eurasia. The geography of the Armenia posed major challenges and opportunities for Palaeolithic hunter gatherer populations, with its mosaic of distinct ecological niches, large temperature gradients, and strong seasonal fluctuations across elevation gradients. This, in turn, make Armenia an ideal natural laboratory for testing models of climatic impact on hominin settlement patterns and population dynamics. The lecture will present two on-going projects in two eco-geographic regions within Armenia. The first is Kalavan 2, a Middle Palaeolithic open-air site located at 1630 masl on the northern slopes of the Areguni Mountains north of Lake Sevan. The second area is close to Ararat village at around 700 masl. Preliminary results and future directions of research will be presented in the lecture.

Heinrich Events: An Unintentional Discovery And Its Possible Consequences for the future

In the mid 80ties an environmental impact assessment in relation to deep-sea dumping of medium-to-high level radioactive waste was carried out in the eastern margins of the Mid Atlantic Ridge next to the Bay of Biscaye. In one of the box corers recovered for radionuclide analysis a volcanic rock was found that triggered interest because of an unexpected geochemical feature on its surface. Subsequent investigations on the bordering sediment layer revealed hints on a massive ice rafting event possibly released from rapidly collapsing circum-Atlantic ice shields. The search for more of these events in numerous sediment cores exhibited a total of 11 layers since the end of the Saalian/Illinoian glaciation (OIS 6/5 to 2/1). The six events identified in the period OIS 4 to 2 indicated oceanographic conditions in the Northeast Atlantic Ocean that were different to those that prevailed during most time of this glacial period. Later, several authors proposed mechanisms that could have triggered the collapses, e.g. the Binge-Purge model (MacAyeal, 1993) or, access of relatively warm water to the grounding lines in conjunction with isostatic movements (Bassis, 2017).

One of the consequences of rapid ice shield collapses is sea level rise. Paleo data report rates of up to several meters per century over a period of several centuries. The process described by Bassis et al. resembles to what nowadays can be observed along the ice margins of Greenland and the Antarctic where (man-made) warmed ocean water attacks the grounding lines. If this initiates something like a Heinrich event this is of widespread consequence for coasts, from displacement of populations to marine pollution.

Research on past Heinrich events is important for understanding the future developments of the existing ice shields and climate change.
