Abstract: The determination of exposure ages, erosion rates, or terrigenous fluxes into the oceans with meteoric cosmogenic 10Be or 10Be/9Be ratios requires knowledge of the depositional fluxes of this nuclide (Willenbring and von Blanckenburg, 2010). The spatial distribution of these fluxes depends on stratospheric production, solar and paleomagnetic modulation, and atmospheric restribution. To allow for the estimation of such fluxes at a given site, and to enable the GIS-based calculation of such fluxes that integrate over large spatial areas (river basins, ocean basins) we provide global maps and excel sheets interpreted to present the average Holocene 10Be fluxes and an estimate of their uncertainty as modeled by atmospheric distribution models (Heikkilä et al., 2013, Heikkilä et al., 2013, Heikkilä and Smith, 2013).

Abstract: The pilot site Ketzin is the longest-operating European onshore CO2 storage site and the only one in operation in Germany. Since the beginning of the storage activity at the end of June 2008, more than 56.000 tons of CO2 were successfully injected until December2011. CO2 is injected into a saline aquifer. It consists of 630 m to 650 m deep sandstone units of the Stuttgart Formation of Upper Triassic age. They were deposited in a fluvial environment. A sequence of about 165 m of overlaying mudstones and anhydrites is sealing the storage complex and act as a caprock. The research and development programme at Ketzin is among the most extensive worldwide in the context of geological CO2 storage. Research activities have produced a broad data base and knowledge concerning the storage complex at Ketzin as well as generic cognition This data publication compiles and reviews the operational data recorded at the Ketzin pilot site for 2013 (injection data: CO2 mass flow, temperatures, pressures, flow rate, etc.).

Abstract: The here documented GIS map and dataset contains a collection of Last Glacial Maximum (LGM, ~21k yBP) paleoenvironmental data. It is the first result of a project that aims to acquire, produce and publish GIS datasets from non-GIS based sources such as analogous maps, textual informations or figures of scientific publications for prehistoric time slices. In combination with modelling results and already available GIS-datasets related to the mentioned time frame, it should enable other researchers and members from other projects to use the maps in their work, properly cited and referenced. The map shows LGM land ice sheets, paleo-stream networks and inland water in Europe, a sea-level adapted (-120m) land mass and a Köppen-Geiger climate classification derived from climate model data.

Abstract: This is a plugin for QGIS to interface the openModeller software package. OpenModeller is a software framework for species’ potential distribution modelling. The package includes (among other program files) the om_console.exe executable which is used for the modelling process. The program file is controlled by a configuration file and needs several files as input data. The configuration file contains the paths to the input data, configuration parameters for the output data and the selected modelling algorithm (GARP, Bioclim, Maxent, etc.). Further input data is the occurrence file which contains the occurrence data for a species with a label and geographic coordinates in longitude/latitude notation. The last part is the environmental data that contains environmental variables such as climate or topographic data. The plugin enables the user to select point and raster layers and a modelling algorithm in QGIS which are then converted (in case of the occurrence data) and copied to a new folder structure and written into the configuration file accordingly, depending on the selection and assignment. Subsequently, the generated files and project folder can be directly used by the om_console executable.

Abstract: This keynote speech was held at the 11th Conference on Hunting and Gathering Societies (CHAGS 11) in Vienna, Austria, in September 2015. It comments on the establishment of the International Society for Hunter-Gatherer Research and the new Journal “Hunter Gatherer Research” and it presents ideas about the future orientation of this interdisciplinary field of study. Drawing on examples from first-hand ethnography with the Batek of Malaysia, with Australian Aborigines and with Hai//om San from southern Africa the contribution outlines a new approach in hunter-gatherer studies that explores the notion of “hunter-gatherer situations”.

Abstract: Our research interests in palaeo-studies in East Africa remain high, partly because of the Out-of-Africa hypotheses predicting Homo sapiens origin to be situated in East Africa. Since several decades archaeologists and geoscientists explore suitable sites to answer related questions. Simultaneously, analytical methods applied to the archives improved in their sensibility or resolution over the given time. The amount of published scientific data is enormous, but has to be carefully checked on their robustness compared to modern standards. Therefore, it is necessary to compile datasets and excerpt the given data that are source of scientific interpretations (e.g., palaeoenvironment, palaeoclimate, evolution patterns, time models etc.). In addition, the names of the study sitesin East Africa are often transcribed from different languages or hold several synonyms for various reasons. Thus, we decided to use a semantic wiki to have the advantage of queryable structured data combined with the ability of web based frontend for collaborative editing of the content. The presented application is based on Semantic Mediawiki (SMW), an extension of the famous Mediawiki software, the widely used wiki system mostly developed and maintained by the Wikimedia foundation as the software base of Wikipedia. The SMW extension allows to enter structured semantic data on wiki pages. This data can then be queried through several interfaces within the wiki and the Mediawiki API as well as an SPARQL endpoint for access from external applications. Query results can be exported in several well known formats, such as CSV, XML, JSON, and more. It is also possible to display query results directly in the wiki, using a number of provided display formats, like tables, data graphs or maps. The presented system allows to collaboratively develop and maintain a data basis and thus implements a collaborative research environment (CRE). The data can be exported for use in scientific software packages for e.g. statistical or GIS analysis. A further outcome of the approach is a domain data model of the structured information stored in the system, which can be formalised and mapped to existing data bases to allow data integration between applications. Details of published and unpublished archaeological and geological sites/localities in East Africa are collected in the presented wiki including their bibliographical reference. For example from sediment records, results from available sedimentological/chemical/biological proxy data (e.g., grain size, total organic carbon, stable isotopes, diatoms, ostracods, magnetic susceptibility) are copied into the database including their spatial resolution. Related dating samples (i.e., 14C, OSL, TSL) are also included with their metadata and lab-codes.

Abstract: In the recent past data base systems providing information on early humans and their environment are becoming more and more important and increase rapidly in number. However, this increase in different DB systems is concomitant with an increasing redundancy in the digital information stored in these database systems. Therefore, in this study we explore ways to reduce redundancies due to multiple storage of data and, hence, we show solutions to minimize the requirements to store and manage digital information in the prehistory and paleoenvironment domains. The example is based on the database systems of the DFG financed SFB 806: “Our Way to Europe” and the Heidelberg Academy of Sciences and Humanities project entitled: “The Role Of Culture in Early Expansion of Humans (ROCEEH). We focus especially on the spatial data available in both systems as well as on the environmental information. Therefore, we examine and test exchange interfaces based on Spatial Data Infrastructure technology (OGC Standards) and metadata/schema mappings. The poster presents currently implemented interfaces of both data base systems in terms of their main commonalities and differences. Based on this overview, we discuss ways of direct links between the DB systems. Moreover, we identify procedures that need to be developed in the future to integrate and exchange data between both systems. We show that DB-linking activities based on the OGC standards yield valuable results and lead to a more efficient, sustainable management of these DB systems providing added values for the related research groups.
