Description
Summary:Project KNIPAS (Knipovich Ridge Passive Seismic Experiment), a collaborative effort led by the Alfred-Wegener-Institute with partners from the University of Potsdam, Germany, and the Institute of Geophysics, Polish Academy of Sciences, Warsaw, Poland, installed a network of 26 broad-band ocean bottom seismometers along the ultraslow-spreading Knipovich Ridge. The presented data set covers the continuous records of the 23 stations of the core network provided by the DEPAS instrument pool. The instruments were spaced at roughly 20 km intervals to either side of the rift axis covering about 160 km along axis between 75.7°N and 77.1°N. The network design was optimized for detecting along-axis variations in seismicity at the scale of spreading segments. Instrument deployment started during RV Polarstern cruise PS100 on July 20 1016. Instrument recovery was completed during RV Maria S. Merian cruise MSM68 on October 9 2017. The network was denser around Logachev Seamount. Refraction seismic lines across Logachev Seamount were acquired by RV Maria S. Merian cruise MSM67 on September 19 and 20 in 2017. For that purpose, short-term stations KNR24-27 were deployed next to stations KNR05-08 whose batteries had expired by the time of the seismic survey (cruise PS109).
