Facilities and Instruments
The Bremen Magnetics Lab, founded in 1985 by Ulrich Bleil, commands over supersensitive magnetometers to measure the magnetic remanence, hysteresis and susceptibility of rocks. We can determine sedimentary physical properties by non-destructive core logging both on- and offshore. Our innovative benthic EM profiler NERIDIS III was developed at MARUM to map the magnetic susceptibility and electric conductivity of the seabed. All these facilities can also be used by science and industry partners on cooperation and service terms.

Service and Cooperation

Bremen Laboratory for Paleo-, Rock and Environmental Magnetics
Team: Thomas Frederichs (Lab Manager), Christian Hilgenfeldt (System Engineer), Liane Br├╝ck (Lab Technician), Heike Piero (Data Management)
Techniques: The Bremen Magnetics Lab is specialized in measuring weakly magnetic materials such as sediments and minerals. We cover all modern paleo- and rock magnetic methods: Natural and laboratory remanences, magnetic hysteresis, susceptibility and anisotropy, thermomagnetics at low (4-400K) and high (270-800K) temperatures and fields up to 7T, FORC analyses, REM of magnetic extracts. more ┬╗

Core Logging in the Lab and at Sea
Team: Thomas Frederichs (Lab Manager), Hendrik M├╝ller (Color Spectrometry), Christian Hilgenfeldt (System Engineer), Liane Br├╝ck (Lab Technician), Heike Piero (Data Management)
Techniques: Sediment physical properties such as susceptibility, conductivity, porosity, density, sound velocity, and color are controlled by sediment composition and fabric. These parameters are fundamental as well for geophysical exploration as for the description, correlation and stratigraphy of sediment cores. We conduct core logging and imaging on board of reserach vessels and in our own core logging laboratory. more ┬╗

Technique: Marine Electromagnetics (EM) is an emerging active method to detect seabed potential field anomalies at different scales. These data help to assess hydrocarbon and mineral reservoirs, fresh water seeps or melting zones. We developed the benthic EM profiler MARUM Neridis III to map the magnetic susceptibility and electric conductivity of the surficial seabed sediments to deduct their composition, porosity, stratification and formation conditions. mehr ┬╗

Field and Marine Magnetics
Team Thomas Frederichs, Hendrik M├╝ller, Tilo von Dobeneck
Techniques: Equipped with modern Overhauser magnetometers and gradiometers, we can conduct magnetic surveys at land and in the shallow sea. We also command over professional software for field data processing and interpretation. These systems are extensively used in our field courses and study projects, e.g. for archeological, structural, engineering and marine geology topics. more ┬╗
