Kövesligethy Radó Seismological Observatory (Geodetic and Geophysical Institute, Research Centre for Astronomy and Earth Sciences, Hungarian Academy of Sciences (MTA CSFK GGI KRSZO))
Abstract: The Hungarian National Seismological Network (HNSN) is a permanent seismological network operated by the Kövesligethy Radó Seismological Observatory (Geodetic and Geophysical Institute, Research Centre for Astronomy and Earth Sciences, Hungarian Academy of Sciences). The main purpose of the network is the continuous monitoring of the seismicity of Hungary and to provide high quality data for the seismological and geodynamic scientific research. The first digital seismological station of the HNSN started its operation in 1992. The network covers the entire Hungarian territory although the geometry is driven by the topography. Most of the stations are concentrated in hilly/mountain regions to move away from the human related activities and to avoid basin effects. All data are acquired in real-time to the HNSN data centre located at the Kövesligethy Radó Seismological Observatory in Budapest. The HNSN follows an open data policy, seismic waveform data are available in real time without any restriction within from the HNSN data centre as well as from the European Integrated Data Archive via the GEOFON data centre.

Abstract: The network, which consisted of both land and ocean bottom seismographs, functioned from October 2005 until its deinstallation in March 2007 as part of the Exploring the Geodynamics of Subducted Lithosphere Using an Amphibian Deployment of Seismographs (EGELADOS) project. The network, which covered the entire southern Aegean Sea from the Peloponnesus region in the west to western Turkey in the east, was designed to study seismicity as well as the distribution of the elastic and anelastic material properties in the Hellenic subduction zone to better understand its complex geotectonic setting and evolution. The network encompassed 45 Güralp 60-second seismometers, four Streckeisen STS-2 seismometers, and seven 1-Hertz Mark seismometers at land sites. The seismometers were supplemented by 22 ocean bottom seismographs equipped with Güralp 60- second seismometers and broadband hydrophones. In addition, the network was designed to incorporate the seven permanent broadband seismographs of the GeoForschungsNetz (GEOFON) network and one Mediterranean Very Broadband Seismographic Network (MedNet) station. Waveform data is available from the GEOFON data centre, under network code Z3, and is fully open.

Reinsch, Thomas • Henninges, Jan
Abstract: Reinsch et al. (2013) describe the installation of a novel fibre optic cable behind the anchor casing of the geothermal well HE-53, Hellisheiði geothermal field, SW Iceland. Within this data publication, DTS temperature data, acquired together with optical time domain reflectometry (OTDR) data during three different field campaigns are presented. Data have been acquired during the installation in spring 2009, during the onset of a production test in summer 2009 and after a 8.5 month shut-in period in summer 2010.

Abstract: The ability of any satellite gravity mission concept to monitor mass transport processes in the Earth system is typically tested well ahead of its implementation by means of various simulation studies. Those studies often extend from the simulation of realistic orbits and instrumental data all the way down to the retrieval of global gravity field solution time-series. Basic requirement for all these simulations are realistic representations of the spatio-temporal mass variability in the different sub-systems of the Earth, as a source model for the orbit computations. For such simulations, a suitable source model is required to represent (i) high-frequency (i.e., sub- daily to weekly) mass variability in the atmosphere and oceans, in order to realistically include the effects of temporal aliasing due to non-tidal high-frequency mass variability into the retrieved gravity fields. In parallel, (ii) low-frequency (i.e., monthly to interannual) variability needs to be modelled with realistic amplitudes, particularly at small spatial scales, in order to assess to what extent a new mission concept might provide further insight into physical processes currently not observable. The updated source model provided here attempts to fulfil both requirements: Based on ECMWF's recent atmospheric reanalysis ERA-Interim and corresponding simulations from numerical models of the other Earth system components, it offers spherical harmonic coefficients of the time-variable global gravity field due to mass variability in atmosphere, oceans, the terrestrial hydrosphere includ- ing the ice-sheets and glaciers, as well as the solid Earth. Simulated features range from sub-daily to multiyear periods with a spatial resolution of spherical harmonics degree and order 180 over a a period of 12 years. In addition to the source model, a de-aliasing model for atmospheric and oceanic high-frequency variability with augmented systematic and random noise is provided for a realistic simulation of the gravity field retrieval process.

Abstract: The pilot site Ketzin is the longest-operating European onshore CO2 storage site and the only one in operation in Germany. Since the beginning of the storage activity at the end of June 2008, more than 56.000 tons of CO2 were successfully injected until December2011. CO2 is injected into a saline aquifer. It consists of 630 m to 650 m deep sandstone units of the Stuttgart Formation of Upper Triassic age. They were deposited in a fluvial environment. A sequence of about 165 m of overlaying mudstones and anhydrites is sealing the storage complex and act as a caprock. The research and development programme at Ketzin is among the most extensive worldwide in the context of geological CO2 storage. Research activities have produced a broad data base and knowledge concerning the storage complex at Ketzin as well as generic cognition This data publication compiles and reviews the operational data recorded at the Ketzin pilot site for 2009 (injection data: CO2 mass flow, temperatures, pressures, flow rate, etc.).
