Project Deep OCean Test ARray DOCTAR (OBS part): DEPAS ocean-bottom seismometer operations near the Gloria Fault in 2011-2012

DOI

This is the first deployment of a teleseismic broadband array consisting of 12 three-component broadband ocean-bottom seismometer (OBS) from the German Instrument Pool of Amphibian Seismology (DEPAS) with an aperture of about 50 km in the deep ocean in about 5000 m water depth. The data can be compared with two other deployments on Madeira and in western Portugal mainland which had similar array layouts and recording time spans (network Y7). The broadband data enable furthermore analysis of the crust and upper mantle beneath the array near to the Gloria fault, a major transform fault in the North Atlantic. Recordings of numerous local and regional earthquakes make a precise location of active structures possible. Waveform data is available from the GEOFON data centre, under network code 3J.
