title: Project KNIPAS: DEPAS ocean-bottom seismometer operations in the Greenland Sea in 2016-2017

description: 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).

title: Caledonian metamorphism of metasediments from Franz Josef Land

description: The petrography, detrital zircon age distribution and <sup>40</sup>Ar–<sup>39</sup>Ar ages of three samples from the Nagurskaya drill core of westernmost Franz Josef Land have been analyzed and are compared to similar rocks from the Lomonosov Ridge. The analyzed rocks, from near the base of the drill hole, consist of fine-grained psammitic to semipelitic schists, metamorphosed under greenschist-facies conditions. They are lithologically very similar to the recently analyzed metasediments from the Lomonosov Ridge. The detrital zircon age spectra of the samples from both the Lomonosov Ridge and beneath Franz Josef Land span the Meso- to Palaeoproterozoic with a main peak around 1.6 Ga, similar to lower Neoproterozoic metasedimentary rocks in East Greenland, on Svalbard and northern Norway, as well as from Cambrian sediments in Estonia and Silurian–Devonian sediments on Novaya Zemlya. Biotite in metasedimentary rocks from the Nagurskaya drill core indicate an Early Devonian <sup>40</sup>Ar–<sup>39</sup>Ar metamorphic age of <i>c</i>. 400 Ma, possibly superimposed on an earlier, Ordovician history similar to that of the metasediments from the Lomonosov Ridge at 470 Ma. Previously published <sup>40</sup>Ar–<sup>39</sup>Ar analyses of Nagurskaya muscovite yielded c. 600 Ma ages, characteristic of the Timanian Orogen. Together with the new biotite data, these isotope ages favor the interpretation that the Caledonian suture is located between Svalbard and Franz Josef Land, and the Caledonian deformation front between the latter and Novaya Zemlya.
