Research on geological imaging spectrometry within the framework of CtG focuses on the use of high spectral resolution remote sensing data for geological applications mainly related with natural seepage of oil and gas along fracture and fault systems in leaking oil-gas reservoirs. At the surface, these seeps produce pronounced effects on vegetation structure and cause mineralogical alterations in soil and rock. These can be spectrally characterized by means of the imagery described. The field of imaging spectrometry is at the transition from airborne (solely) to spaceborne data acquisition (supported by airborne underflights). This opens new possibilities for data integration namely multi-sensor approaches and integrated research exploiting field data. The European Space Agency (ESA) are preparing for the ENVISAT mission, to be launched in June 2001, which will carry an imaging spectrometer (MERIS) and an interferometric SAR system (ASAR) amongst other systems. NASA has launched the Terra mission in December 1999 which carries the ASTER sensor which has high spectral resolution optical and thermal channels perfectly suited for geological research.
At present the thematic aim of the research at present is twofold:
developing a framework for integrating imaging spectrometry data with field and subsurface data
The ultimate goal is to progress from static surface measurements to dynamic process-based surface measurements using remote sensing data. In particular, we want to be able to better characterize greenhouse gas emissions from natural hydrocarbon seeps and contribute to understanding the role of these gases in the global change problematics.
The research group on imaging spectrometry is partly based in Delft and partly at the ITC in Enschede. The following Ph.D. research projects are ongoing (reports of those in CtG are included):
Scholte, imaging hydrocarbon microseeps in Azerbaidjan
Kariuki, swelling clay mapping for characterizing expansive soils
* Based at and funded by ITC, not yet accredited in CtG.
** Starting mid-2001 at ITC.
The group has received research funding from Shell and BCRS and has recently been awarded a grant from the European Science Foundation (ESF) to enable the organization of an exploratory workshop on “natural hydrocarbon seeps, global tectonics and greenhouse gas emissions”.
