Messverfahren in MOSAIC


Model Driven Site Assessment, Information and Control 

Contact Person: Dr. Ulrike Werban

MOSAIC is a broad research platform for model supported near surface assessment and build a connection between scientist from different special fields and study areas.

The realization of MOSAIC takes place in order to enlarge the abilities and the competence of the Helmholtz Centre for Environmental Research - UFZ in the field of investigation and observation of extensive natural and anthropogenically influenced systems. The innovative mapping and monitoring technologies of MOSAIC enable high-resolution surveys of complex sub-surface structures and processes. 

The basic concept of MOSAIC is funding on combination of already existing, non invasive methods in areas such as drilling, geophysical measurements and analysis methods. Apart from e.g. advanced Direct Push- technologies, a borehole logging unit there is also a field lab and a mobile swimming platform available.

MOSAIC is a new platform for research in the areas of groundwater, soil and biodiversity aiming at making a quantum leap in investigating test sites in regard to quality, efficiency and speed.

  • Development of monitoring and exploration technologies
  • Parameterization of environmental system for process studies
  • Platform for joint research of UFZ with universities and other research institutions
  • Technology transfer (summer schools, pilot studies)
  • Advanced Direct Push – technologies (e.g. EC-log, MIP-log, Injection-log, SPT-log)
  • Geophysical surfaces methods (e.g. seismics, geoelectrics, EM, GPR),
  • Tomographic and borehole methods (e.g. hydraulic, radar, seismic, geoelectric)
  • Hydrogeological methods (e.g. pumping tests, tracer tests)
  • Methods of onsite analysis.
Alternatively to traditional site investigation approaches there is the adaptive approach applying a dynamic working plan at site investigation where the definition of investigation steps and applied methodology and technology based on the results of the previous investigation steps. This procedure with dynamic working plans, a real time analysis of investigation results (e.g., chemical analyses of obtained samples) and on-site decisions offers clear advantages compared to the traditional approach. Thus, for example, the results are obtained faster with fewer resources and with higher quality, because the best of all suitable methods / technologies can be selected adaptive, but also the number of sampling points can be reduced by the optimisation. However, a prerequisite for such a procedure is that a suitable pool of methods / technologies is available and applicable.
Adaptive site investigation approach

Examples of application are, among others, characterization of mega sites, investigation of catchment areas, characterization of aquifers, investigation and remediation of mining lakes, investigation of contaminated sites.
