Ocean Kinetic Energy Backscatter Parametrization on Unstructured Grids: Impact on Global Eddy-Permitting Simulations
;
; ; ; (Journal of Advances in Modeling Earth Systems, 2020)
In this study we demonstrate the potential of a kinetic energy backscatter scheme for use in global ocean simulations. Ocean models commonly employ (bi)harmonic eddy viscosities causing excessive dissipation of kinetic ... -

The transient climate response (TCR) is 20% higher in the Alfred Wegener Institute Climate Model (AWI‐CM) compared to the Max Planck Institute Earth System Model (MPI‐ESM) whereas the equilibrium climate sensitivity (ECS) ... -
Ocean resurge-induced impact melt dynamics on the peak-ring of the Chicxulub impact structure, Mexico
; ; ;; ; ; ; ; (International Journal of Earth Sciences, 2021-03-18)
Core from Hole M0077 from IODP/ICDP Expedition 364 provides unprecedented evidence for the physical processes in effect during the interaction of impact melt with rock-debris-laden seawater, following a large meteorite ... -
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
Müller, Sebastian; Zech, Alraune; (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 ... -
Oldest entirely preserved sponges and other fossils from the Lowermost Cambrian and a new facies reconstruction of the Yangtze platform (China)

Oldest entirely preserved sponges and other fossils from the Lowermost Cambrian and a new facies reconstruction of the Yangtze platform (China)
Steiner, M.; Mehl, D.;; Erdtmann, B.-D. (Berliner geowissenschaftliche Abhandlungen, 1993)
Eine Faziesrekonstruktion W1d Korrelation obersinischer-unterkambrischer Schichten der Yangtze-Plattform (Südchina) wird vorgestellt. Dabei wird zwischen geschütztem Becken, Schwelle W1d tiefem Becken unterschieden. Die ... -
Oligocene emplacement of the Eclogite Zone of the central Tauern Window, Eastern Alps, Austria
Kühn, Alexander;; Ring, Uwe (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 ... -
Oligocene vegetation of Europe and western Asia—Diversity change and continental patterns reflected by plant functional types
; Erdei, Boglárka; François, Louis; Henrot, Alexandra-Jane; Mosbrugger, Volker; Popova, Svetlana (Geological Journal, 2020)
Spatial vegetation patterns potentially reflect coeval continental climate variations which are also impacted by palaeogeographical settings. Plant functional types (PFTs) and their distribution, frequently applied in ... -
Olivine aggregates reveal a complex collisional history of the main group pallasite parent body
; (Meteoritics & Planetary Science, 2022-04-08)
Olivine aggregates, bodies found in pallasites that consist of olivines with coherent grain boundaries and minor amounts of Fe‐Ni and troilite, likely represent well‐preserved samples of different mantle regions of pallasite ... -
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 gravity wave parameterisation in vicinity of low‐level blocking
(Atmospheric Science Letters, 2022-03-07)
This note is framed as an open question to the community regarding parameterisation schemes using the blocking layer depth to reduce the orographic gravity wave drag. It is the purpose of this note to argue that the current ... -
On incoherent diffractive imaging
(Acta Crystallographica Section A, 2021-08-27)Incoherent diffractive imaging (IDI) promises structural analysis with atomic resolution based on intensity interferometry of pulsed X‐ray fluorescence emission. However, its experimental realization is still pending and ... -
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 ... -

On the Along‐Slope Heat Loss of the Boundary Current in the Eastern Arctic Ocean
; ; Lenn, Yueng‐Djern; ; ; ; ; ; ; ; (Journal of Geophysical Research: Oceans, 2021-02-15)
This study presents recent observations to quantify oceanic heat fluxes along the continental slope of the Eurasian part of the Arctic Ocean, in order to understand the dominant processes leading to the observed along‐track ... -
On the contribution of the Geodetic Institute Potsdam to the International Latitude Service - paper presented on the occasion of the centennial of the first observations of the International Latitude Service in 1999
