Automated static and moveout corrections of high-resolution seismic data from the Baltic Sea
(Near Surface Geophysics, 2019)High-frequency multichannel seismic systems provide detailed images of the shallow marine subsurface. In order to exploit the redundancy inherent in such data optimally, traveltime corrections need to account for normal ... -

Automatisierte universelle CCD-Astrometrie von Kleinplaneten
(Univ. Dresden, 2005)Für Zwecke der differentiellen astrometrischen Positionsbestimmung von Kleinplaneten werden heutzutage verbreitet CCD-Beobachtungen eingesetzt. Insbesondere im Rahmen von Follow-up-Beobachtungsprogrammen sind eine Vielzahl ... -
Bacterial Stern layer diffusion: experimental determination with spectral induced polarization and sensitivity to nitrite toxicity
(Near Surface Geophysics, 2019-08-07)Spectral induced polarization signatures have been used as proxies for microbial abundance in subsurface environments, by taking advantage of the charged properties of microbial cell membranes. The method's applicability, ... -
Baseline Vector Repeatability at the Sub‐Millimeter Level Enabled by Radio Interferometer Phase Delays of Intra‐Site Baselines
(Journal of Geophysical Research: Solid Earth, 2023-03-17)We report the results of position ties for short baselines at eight geodetic sites based on phase delays that are extracted from global geodetic very‐long‐baseline interferometry (VLBI) observations rather than dedicated ... -
Basin‐scale estimates of greenhouse gas emissions from the Mara River, Kenya: Importance of discharge, stream size, and land use/land cover
(Limnology and Oceanography, 2022-06-23)Greenhouse gas fluxes (CO2, CH4, and N2O) from African streams and rivers are under‐represented in global datasets, resulting in uncertainties in their contributions to regional and global budgets. We conducted year‐long ... -
Bathymetric Control on Borchgrevink and Roi Baudouin Ice Shelves in East Antarctica
(Journal of Geophysical Research: Earth Surface, 2021-10-07)The stability of ice shelves and drainage of ice sheets they buttress is largely determined by melting at their atmospheric and oceanic interfaces. Subglacial bathymetry can impact ice shelf stability because it influences ... -
Bathymetry Beneath Ice Shelves of Western Dronning Maud Land, East Antarctica, and Implications on Ice Shelf Stability
(Geophysical Research Letters, 2020-06-13)Antarctica's ice shelves play a key role in stabilizing the ice streams that feed them. Since basal melting largely depends on ice‐ocean interactions, it is vital to attain consistent bathymetry models to estimate water ... -
Beating 1 Sievert: Optimal Radiation Shielding of Astronauts on a Mission to Mars
(Space Weather, 2021-09-03)Space radiation is one of the main concerns in planning long‐term human space missions. There are two main types of hazardous radiation: solar energetic particles (SEP) and galactic cosmic rays (GCR). The intensity and ... -
Behaviour of tiang tongkat foundation over Pontianak soft organic soil using 3D-finite element analysis
(TU Freiberg, 2008)Peat deposits are distributed mostly along the coast of West Kalimantan, Indonesia, particularly in and around the provincial capital of Pontianak. There are many problems with constructing over peat soil as the existence ... -
Benefits of non-tidal loading applied at distinct levels in VLBI analysis
(Journal of Geodesy, 2020-08-31)In the analysis of very long baseline interferometry (VLBI) observations, many geophysical models are used for correcting the theoretical signal delay. In addition to the conventional models described by Petit and Luzum ... -
Berechnung des seismischen Streufeldes für anisotrope Störungen
(Univ. Stuttgart, 2006)Vorliegende Arbeit beschäftigt sich mit der Streuung der seismischen Wellen infolge unterschiedlicher, unter Anderen anisotroper, Störungen der sphärischen Symmetrie des Modells. Die Streuwellen übelagern das Referenzsignal ... -
Best practice of macroseismic intensity assessment applied to the earthquake catalogue of southwestern Germany
(Historical Earthquakes, Paleoseismology, Neotectonics and Seismic Hazard: New Insights and Suggested Procedures, 2020)The earthquake catalogue of southwestern Germany for the last millennium now contains about 30,000 digital macroseismic intensity data points (IDPs). Intensity assessments are based mainly on primary sources using the ... -
Bestimmung von Ozonabbauraten über der Arktis und Antarktis mittels Ozonsonden- und Satellitendaten
(Univ. Potsdam, 2006)Diese Arbeit beschäftigt sich mit der chemischen Ozonzerstörung im arktischen und antarktischen stratosphärischen Polarwirbel. Diese wird durch Abbauprodukte von anthropogen emittierten Fluorchlorkohlenwasserstoffen und ... -
Between Broadening and Narrowing: How Mixing Affects the Width of the Droplet Size Distribution
(Journal of Geophysical Research: Atmospheres, 2023-04-12)Entrainment and mixing play an essential role in shaping the droplet size distribution (DSD), with commensurate effects on cloud radiative properties or precipitation formation. In this paper, we use a model that considers ... -
