    Earthquake model for the European-Mediterranean Region for the purpose of GEM1 (2010)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report STR
    Details
    Publication Date: 2020-02-12
    Description: The seismicity data file used for this study is represented by the earthquake catalogue CENEC for Europe north of 44°N (Grünthal et al. 2009a). This paper describes in detail how this homogeneous data file in terms of moment magnitudes Mw (with Mw greater than 3.5) has been derived. The degree of harmonization achieved in CENEC is quantitatively analysed in Grünthal et al. (2009b).

    A global survey of sporadic E layers based on GPS radio occultations by CHAMP, GRACE and FORMOSAT–3 / COSMIC (2010)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report STR
    Details
    Publication Date: 2020-02-12
    Description: The ionosphere is a part of the upper atmosphere stretching from a height of about 60 km to more than 1 000 km. A certain fraction of the gas particles in that region is ionised by solar extreme ultra violet radiation. Since electromagnetic waves are influenced and significantly modified by ionospheric free charge carriers, the altitude range is of great scientific interest. GPS satellites emit electromagnetic waves on L – band frequencies travelling through the ionosphere and lower neutral atmosphere. Subsequently, they are received by low–Earth orbiting satellites. Consequently, the signals are affected by strong electron density gradients at altitudes above approximately 80km and by atmospheric density, pressure and water vapour content in the troposphere and stratosphere. This measurement method is termed radio occultation technique and it allows to receive a global picture of ionospheric and lower neutral atmospheric conditions. This study focusses on the detection and analysis of sporadic E layers from GPS radio occultation measurements on a global scale. Sporadic E layers are localised patches of relatively high electron density appearing in the E region of the ionosphere. They are represented in GPS signals as intense fluctuations. This work reveals that global sporadic E occurrence rates underlie variations on different time scales. It is demonstrated that the sporadic E occurrence depends on several geophysical parameters and it is subject to coupling processes between the neutral atmosphere and ionosphere. For example, the global sporadic E occurrence is oriented along Earth’s magnetic field. It is shown additionally that sporadic E altitudes are subject to tidal winds and that its annual cycle varies with meteor influx.

    Changes in monsoonal precipitation and atmospheric circulation during the holocene reconstructed from stalagmites from Northeastern India (2010)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report
    Details
    Publication Date: 2020-02-12
    Description: The focal point of my thesis is the extraction of climatic signals archived in stalagmites from NE India. High uranium concentration in the stalagmites ensured excellent age control required for successful high-resolution climate reconstructions. Stable isotope (δ18O and δ13C) and grey-scale data allow unprecedented insights into millennial to seasonal dynamics of the summer and winter monsoon in NE India.

    Hyperspectral algorithms : report in the frame of EnMAP preparation activities (2010)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report
    Details
    Publication Date: 2020-02-12
    Description: Against the background of EnMAP preparation analyses have been carried out on the status of research in various areas of hyperspectral remote sensing for the use of existing algorithms in the EnMAP application box. The aim was to compose the status of research in Germany and internationally. Therefore, in various fields of expertise applied and accordingly available algorithms and products based on hyperspectral data has been evaluated and documented. The intention has been to demonstrate and to evaluate the added value of hyperspectral remote sensing to multispectral methods for each product. For this purpose analyses have been carried out by different research groups which were based on the specialty and the experience of each group. Hereby a summary was created of each major application perspective and the relevant remote sensing derived variables and significant processing algorithms (state-of-the-art) belonging to this context. Based on this, the research delivers, as a result, a recommendation which of the algorithms should be implemented into the Applikationsbox of EnMAP. Tests of the algorithms or their implementation were not part of the analyses. However, notes have been given on what algorithms should be tested in the context of a detailed preparation phase. An assessment to the further R & D requirements in the development of algorithms has been made on this basis.

    Late Pleistocene-Holocene sedimentary processes at the active margin of South-Central Chile : marine and lacustrine sediment records as archives of tectonics and climate variability (2010)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report
    Details
    Publication Date: 2020-02-12
    Description: In my thesis, I studied marine and lacustrine sediment cores from different depositional provinces along the south-central Chilean margin with the overall objective to identify their records of paleoclimate and paleotectonics. First of all, I investigated sedimentary sequences that were recovered within the margin-parallel trench system (cp. Figure 1.2) and hence constitute long-term recorders [...] of the sediment transport between the continent and the abyssal zone of the lower plate.

    XRD of Cuttings of the KTB Pilot Hole HB1 (2010)

    Publication Date: 2021-08-13
    Description: Abstract
    Description: The qualitative and quantitative phase analyses were performed in the KTB field laboratory by x-ray powder diffraction using SIEMENS D 500 diffractometer. During early stages of the KTB project a new method for quantitative phase analysis was developed (see references below). The method is based on the comparison of the diffraction spectrum of the unknown sample with those of pure minerals. The powder diffraction data of the minerals are stored in a database built up of 250 natural minerals separated from various types of igneous and metamorphic rocks. The complete analyses (radiation: Cu K alpha, lambda: 1,5405Å, stepwidth: 0,01°, counting time 2 sec/step, angle 2-80°) was carried out automatically including computations. The results of this quantitative phase analysis were used e.g. to check thin section petrography (and vice versa) and to construct a \"mineralogical rock composition log\".
