MARMARA-DM - Seismometer - RAW dataset

Metadata

Instrument: Guralp CMG-40T 3 component broadband seismometer (30 s-50 Hz)
Investigator: Stephen Monna (INGV)
Project: ESONET-MARMARA-DM
Observatory: SN-4

Abstract: This digital database comprises seismological data recorded continuously during the MARMARA-DM 1 project by a 3 component broadband seismometer. The sensor was installed on a GEOSTAR-class deep-sea multidisciplinary observatory, deployed in the Marmara Sea at a depth of 167 m. The seismometer is installed in a dedicated vessel integrated in a separate structure connected to the observatory via a special mechanical release. To guarantee a good coupling with the sea bottom, the structure is disconnected just after the observatory touch-down and kept linked to the frame by a slack rope (Favali et al., 2006). The sensor was connected to a 24 bit digitizer, and its time reference came from an external rubidium clock connected to the digitizer.

Purpose: The major scientific goal of the SN-4 experiment is to contribute to the knowledge on the relationship between gas seepage and seismic signals. To observe a large variety of seismic signals we use a broadband seismometer. The deployment site is on the sea prosecution of the active North Anatolian fault,which has been the source of many destructive earthquakes, and presents a continuous seismic activity and methane degassing.
