Paleomagnetism and Marine Geology Laboratory
The research performed at the Paleomagnetism and Marine Geology Laboratory of ISMER mostly uses the various magnetic and physical properties of sedimentary sequences to reconstruct variations in Earth’s magnetic field, establish high-resolution chronostratigraphy, and develop natural hazards and (…)

Alternating gradient force magnetometer
Friday 11 April 2008
An alternating gradient force magnetometer was recently installed in the laboratory. This magnetometer is used to determine the magnetic mineralogy and granulometry of the magnetic grains present in the sediments.

Corers
Friday 22 February 2008
The laboratory owns or have access to various models of corers that can be used onboard of an oceanographic vessel : piston, gravity or box corer and "multicorer". The laboratory owns also a piston corer that is used on lakes (on frozen lakes or on a special platform).

Core opening bench
Friday 22 February 2008
With this bench, cores of different diameters and lengths can be cut in halves. Although the tubes are generally made of PVC, it is possible to cut some metallic tubes by changing the cutting blades. From half cores, we can :
- Photograph the sediment with the SmartCIS core scanner
- (…)
X-Rite DTP22 spectrophotometer
Friday 22 February 2008
This spectrophotometer can be used to quantify the color of the sediments. The reflectance is measured in the visible spectrum at 10nm interval. In addition the reflectance data can be converted to the following color spaces : HSV, LAB and XYZ.

SMART-CIS high resolution core scanner
Friday 22 February 2008
This instrument overlaps pictures of a sediment core taken from a high resolution numeric camera. The file exportation is made in .JPG for display or in .TIF for image analysis.

Laser granulometer
Friday 22 February 2008
The laboratory has also access to a Beckman Coulter LS-13320 laser granulometer. The granulometer uses the laser diffraction to determine the grain sizes. The measured sizes vary between 0.04 to 2000 μm.

MSCL analysis bench
Friday 22 February 2008
The Multi Sensor Core Logger (MSCL) can simultaneously measure several parameters at the same interval and at high resolution. This device can accept sediment cores from various lengths ant diameters. It also accepts whole or split cores.
Multi Sensor Core Logger from Geotek (…)
Cryogenic magnetometer
Friday 22 February 2008
This state-of-the-art magnetometer is designed to measure very small magnetic variations in continuous u-channel samples at 1 cm intervals. The magnetometer is equipped with three SQUIDS (Superconducting QUantum Interference Device Sensor) that are cooled to six Kelvins with a new type of (…)
