Field laboratories

A geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the surface by putting electrodes in the ground. Composed of an automated 56-channel system from AGI, with max 10 meter electrode spacing. Related software available for 2D and 3D inversions.

GPR - PULSE EKKO

A geophysical method that uses radarpulses to image the subsurface. GPR uses high-frequency radio waves. A GPR transmitter emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivities, it may be reflected or refracted or scattered back to the surface.Equipped with a 50, 100 and 500 MHz antenna.

Exploranium Gamma-ray spectrometer is an instrument for measuring the distribution (or spectrum) of the intensity of gamma radiation. Our spectrometer is measuring in 256 bands, with automatic analysis for K, U, and Th.

Magnetic susceptibility meter KT-10 from TerraPlus SM20 from GF Instruments is designed especially for field analysis and classification of rock types or drill core samples. Those measurements allow basic differentiation of rocks (diamagnetic, paramagnetic and ferromagnetic) and their precise susceptibility quantification.

Time-domain EM (TEM-FAST) is  geophysical tool for time-domain electromagnetic sounding. Will provide 1D measurements of varying conductivity with depth, when spatially repeated can deliver 3D subsurface models.

The EM31 - Geonics (and its family EM34, and EM38 systems) measure  the terrain conductivity, in phase response, and indirectly magnetic susceptibility of rock, soil, fill, pore fluids, and metal using frequency domain electromagnetic waves. The system has no datalogger connected to it.

RAMSES-ACC and RAMSES-ARC are  stand-alone highly integrated hyperspectral radiometers for the UV and/or VIS spectral range. Small size and very low power consumption make them suitable for hand-held and autonomous applications. The sensors are part of the RAMSES radiometer family, which is especially designed for combining precision hyperspectral light measurements with a maximum of flexibility

The bbe FluoroProbe is a highly sensitive instrument for the analysis of microalgae in the water. The submersible FluoroProbe quickly and reliably determines chlorophyll-a concentrations in situ and in real time by fluorescence measurement. Recorded data are displayed online or stored internally. The FluoroProbe discriminates algae classes even in complex mixtures due to the spectral properties of green algae, blue-greens (cyanobacteria), brown algae consisting of diatoms, dinoflagellates, chrysophytes, and cryptophytes. The use of the FluoroProbe replaces a considerable amount of laborious analytical work in the lab.
