The OpenFIRE service provides open access to all original seismic reflection data and processed data products of the Finnish Reflection Experiment (FIRE). Also included are complementary summaries of geological descriptions and interpretations and pertaining scientific references. The data can be browsed and accessed via the OpenFIRE map interface or with a filtering table. Geological descriptions are provided on dedicated FIRE profile-specific pages.

The Finnish Reflection Experiment
The Finnish Reflection Experiment (FIRE) dataset consists of seismic reflection data from 2,104 km of common mid-point (CMP) lines. The four FIRE transects cross-cut several geologically and economically important features of Fennoscandian Shield such as the Archaean–Proterozoic boundary and Outokumpu ore district.
The original FIRE project took place between 2001 and 2005. It was conducted in co-operation between the Geological Survey of Finland (GTK), the Institute of Seismology at the University of Helsinki and the Institute of Geosciences and the Sodankylä Geophysical Observatory of the University of Oulu. The seismic contractor in the FIRE project was Specgeofizika S.E. together with Machinoexport S.E.
The preliminary report of the original FIRE project can be found in the Special Paper 43 of the Geological Survey of Finland:
