description |
Project SWEAP (Southwest Indian Ridge Earthquakes and Plumes), a collaborative effort led by the Alfred-Wegener-Institute, installed a network of 10 broad-band ocean bottom seismometers (OBS) along the ultraslow-spreading Oblique Supersegment of the Southwest Indian Ridge. The presented data set covers the continuous records of 8 stations of the network provided by the DEPAS instrument pool. One station of the original network could not be recovered, another one did not return data. The instruments were spaced at roughly 15 km intervals in a triangular shape network to either side of the rift axis covering about 60 km along axis between 13°E and 13.8°E and 60 km across axis between 52°S and 52.6°S. The network design was optimized for detecting and locating deep seismicity in the area. The rift valley was filled with soft silica ooze, producing considerable delay of S-phases at selected stations. Instrument deployment started during RV Polarstern cruise ANT-XXIX/2 on December 05 2012. Instrument recovery was completed during RV Polarstern cruise ANT-XXIX/8 on November 26 2013. 5 Refraction seismic lines were acquired by RV Polarstern cruise ANT-XXIX/8 from November 17 to 19 in 2013. All OBS could be synchronized with the GPS clock upon recovery such that skew values describing the clock drift are available for all stations. |
