GeoHazard Core Lab - BO
Geohazard core laboratory: multiproxy analyses of resedimented deposits
It is focused on geohazards in the submarine environment (seismic, landslides, tsunamis) and provide a collaboration environment to acquire geological, geophysical, geochemical and geotechnical data on sediment cores to assess geohazards and their impact.
GEOHAZARD CORE LAB HOUSING:
- Innovative multisensor core-logger, developed by ISMAR-CNR in collaboration with Proambiente with "open" hardware and software technology, able to carry out measurements on both open and closed sediment cores with great detail (less than a tenth of a mm) of some physical properties such as magnetic susceptibility, P-wave velocity, resistivity;
- The Mastersizer 3000 laser diffraction particle size analyzer (0.01µm-3.5mm);
- Optical microscopy;
- Tracer 5i-5g* Portable XRF Spectrometer based on Silicon Drift Detector (SDD) technology - being acquired.
AVAILABLE SOFTWARE
- ChirCor, open software developed at ISMAR-CNR for acquisition of phisical parameters on Sediment cores and generation of synthetic seismograms. (Dal Forno Giulio and Luca Gasperini, 2008. ChirCor: a new tool for generating synthetic chirp-sonar seismograms, Computers & Geosciences, COMPUTERS & GEOSCIENCES, 34, 103- 114
- SeisPrho, open software developed at ISMAR-CNR for seismic data processing and interpretation (Gasperini L., Stanghellini G., 2009. SEISPRHO: An interactive computer program for processing and interpretation of high-resolution seismic reflection profiles, COMPUTERS & GEOSCIENCES, 35, 1497-1507);
- Corlog: Core logger control software (ISMAR-Proambiente);
- Barth: software for magnetic susceptibility acquisition and calibration;
- Pico: software for acquisition of Vp in sediment cores.
RESEARCH FOCUS AND EXAMPLES
The main analytical activities are carried out in the frame of national and international research projects with the main objective to characterize marine sediments deposited during extreme events and to reconstruct sedimentary processes and triggering mechanisms responsible for sediment remobilization (seismic shaking, slope failures, tsunami wave propagation).
Here are some examples of main results obtained within these themes:
