Polarimetric remote sensing of land and snow/ice covers with the Spaceborne Microwave Radiometer WindSat
(Univ. Bremen, 2007)
Microwave remote sensing, polarimetry, radiometer, WindSat, passive. - Measurements from spaceborne microwave radiometers, such as the Scanning Multichannel Microwave Radiometer (SMMR), the Special Sensor Microwave/Imager ...
Deep exploration using long-offset transient electromagnetics: interpretation of field data in time and frequency domain
(
- Geophysical Prospecting
, 2020)
In the framework of the Deep Electromagnetic Soundings for Mineral Exploration project, we conducted ground-based long-offset transient-electromagnetic measurements in a former mining area in eastern Thuringia, Germany. ...
A seismic monitoring approach to detect and quantify river sediment mobilization by steelhead redd-building activity
(
- Earth Surface Processes and Landforms
, 2020)
The role of spawning salmonids in altering river bed morphology and sediment transport is significant, yet poorly understood. This is due, in large part, to limitations in monitoring the redd-building process in a continuous ...
Feld-Kalibrierung geophysikalischer Daten auf kontaminierten Flächen mit Hilfe des GIS-gestützten Visualisierungswerkzeugs GSI3D
(Univ. Köln, 2007)
Der Einsatz geophysikalischer Verfahren zur Untersuchung von Altlasten hat in den letzten Jahren stark zugenommen. Durch Kombination verschiedener Verfahren einerseits und verschiedener Geo-Wissenschaften andererseits ...
Seismic constraints on rock damaging related to a failing mountain peak: the Hochvogel, Allgäu
(
- Earth Surface Processes and Landforms
, 2020-11-29)
Large rock slope failures play a pivotal role in long‐term landscape evolution and are a major concern in land use planning and hazard aspects. While the failure phase and the time immediately prior to failure are increasingly ...
Analyse von Bathymetrie und akustischer Rückstreuung verschiedener Fächersonar- und Sedimentecholot-Systeme zur Charakterisierung und Klassifizierung des Meeresbodens am Gakkel-Rücken, Arktischer Ozean
(Univ. Bremen, 2008)
Im ersten Kapitel erfolgt nach der Zielsetzung und Motivation für die vorliegende Dissertation eine kurze geographische Beschreibung des Arktischen Ozeans und dessen tektonischer Entwicklung.Das Augenmerk gilt dabei dem ...
Source processes and spectral ground motion models of intermediate depth Vrancea (Romania) earthquakes
(Univ. Karlsruhe, 2007)
For successful assessment and mitigation of earthquake hazards, it is necessary to be able to reliably predict the level of ground shaking which has to be expected from future large earthquakes. This prediction of ground ...
Satellite to satellite tracking in the space-wise approach
(Univ. Stuttgart, 2006)
The launch of the champ mission in 2000 has renewed interest in the recovery of the geopotential field from satellite observations which has been a challenging research issue for decades. It was the first dedicated gravity ...
Physical and chemical constraints on core-mantle differentiation in terrestrial planets
(Univ. Bayreuth, 2008)
In this study a physical mechanism and geochemical parameters have been examined in high pressure and high temperature experiments in order to place constraints on the conditions and the manner by which core-mantle ...
Broadband IF circuits for superconductor isolator superconductor (SIS) mixers for the Heterodyne Instrument for the far infrared on the Herschel Space Observatory and for sideband separating mixers
(Univ. Köln, 2007)
This thesis describes the development and manufacturing of the IF circuits for two different heterodyne receivers used for sub-mm radio astronomy. The first project is the broadband 4-8 GHz IF circuitry for the mixer units ...
