Oberbodenabtrag: eine Methode zur großflächigen funktionellen Wiederherstellung von Niedermoorlebensräumen? – Ergebnisse einer Machbarkeitsstudie
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 45; 2015)Abstract: A pilot study was realized in 2013/2014 to investigate the restoration of degraded percolation mires by a large-scale top soil removal. Objectives and results of the study are presented. The project area is ... -
Oberflächenstruktur von Torf und Wasserbewegung auf der Oberfläche
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 48; 2018)Moorflächen sind auf den Kontinenten überall vorhanden. Aus Mooren lässt sich durch Entwässerung und Trocknung leicht der hochporöse Torfgewinnen. Torf ist ein natürliches und ungiftiges Rohmaterial, das wegen seiner ... -

Observations and high-resolution simulations of convective precipitation organization over the tropical Atlantic
; ; Friederichs, Petra (Quarterly Journal of the Royal Meteorological Society, 2020)
High-resolution simulations (grid spacing 2.5 km) are performed with ICON-LEM to characterize convective organization in the Tropics during August 2016 over a large domain ranging from northeastern South America, along the ... -
Observations of Laboratory and Natural Slow Slip Events: Hikurangi Subduction Zone, New Zealand
; ; ; ; ; Kopf, Achim J. (Geochemistry, Geophysics, Geosystems, 2020)
Slow slip events (SSEs) are recognized as an important component of plate boundary fault slip, and there is a need for laboratory friction data on natural samples to guide comparisons with natural SSEs. Here, we compile a ... -
Observations on Astraeospongium meniscum (Roemer, 1948) from the Silurian of western Tennessee; constructional morphology and palaeobiology of the Astraeospongiidae (Calcarea, Heteractinellidae)
Mehl, Dorte; (Berliner geowissenschaftliche Abhandlungen : Reihe E, 1996)
Astraeospongium is found to form secondary calcareous basal skeletons and thus may be attributed to the morphological grouping "coralline sponges". In A. meniscum, a bowl-shaped sponge with a massive skeleton of octactins, ... -
Observing noctilucent clouds
(Internat. Assoc. of Geomagnetism & Aeronomy, 2006)This manual and instruction book was written by a group of active researchers, both professional and amateur. There are chapters giving practical advice for taking visual observations, photographing the clouds with film ... -
Oceanic anoxic event (OAE) 1b - high resolution geochemical studies, Mazagan Plateau and the Vocontian Basin
(Univ. Köln, 2009)Während der Kreide wurden zahlreiche Störungen des globalen Kohlenstoffkreislaufes aufgezeichnet. Diese Störungen führten zu organisch reichen Ablagerungen, den sogenannten ozeanischen anoxischen Ereignissen (OAEs). Der ... -
Offshore Freshened Groundwater in Continental Margins
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; Martin‐Nagle, Renée; ; ; ; ; Trembath‐Reichert, Elizabeth; ; ; (Reviews of Geophysics, 2021-01-04)
First reported in the 1960s, offshore freshened groundwater (OFG) has now been documented in most continental margins around the world. In this review we compile a database documenting OFG occurrences and analyze it to ... -
ogs5py: A Python‐API for the OpenGeoSys 5 Scientific Modeling Package
(Groundwater, 2020-06-16)High‐performance numerical codes are an indispensable tool for hydrogeologists when modeling subsurface flow and transport systems. But as they are written in compiled languages, like C/C++ or Fortran, established software ... -

Oligocene emplacement of the Eclogite Zone of the central Tauern Window, Eastern Alps, Austria
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The EZ is an approximately 20km long and 2–3km wide coherent unit of the Tauern Window in the Eastern Alps. It is sandwiched between the Venedigerand the Glockner Nappe. While rocks in the EZ experienced HP metamorphic conditions ... -
On classification of logging data
(Univ. Clausthal, 2006)Die Erkennung stratigraphischer Einheiten innerhalb von marinen Sedimentablagerungen wird üblicherweise durch eine kombinierte Interpretation von Seismik-, Bohrlochsonden- und Kern-Daten vorgenommen. Im Falle von mehrdeutigen ... -
On intrinsic uncertainties in earth system modelling
(Univ. Potsdam, 2006)Various types of uncertainty plague climate change simulation, which is, in turn, a crucialelement of Earth System modelling. This fact was recognized for example in the Third Assessment Report (TAR) of the Intergovernmental ... -
