Model output for aerosol-induced cooling after the Chicxulub impact

Julia Brugger, Georg Feulner & Stefan Petri
The simulations of the end‐Cretaceous climate and the effects of the impact are carried out with a coupled climate model consisting of a modified version of the ocean general circulation model MOM3, a dynamic/thermodynamic sea ice model, and a fast statistical‐dynamical atmosphere model. Our impact simulations are based on a climate simulation of the end‐Cretaceous climate state using a Maastrichtian (70 Ma) continental configuration. The solar constant is scaled to 1354 W/m2, based on the...

PDToolbox: a Python probability distribution toolbox

Malte Jörn Ziebarth
PDToolbox is a collection of methods helpful for doing probability distribution computations in Python. The aim of the PDToolbox Python module is to provide a set of features, based on simple probability distributions, that are not available from the scipy.stats module. This includes fast batch computations of (weighted) maximum likelihood estimates, computation of critical empirical distribution statistics, and more niche probability distributions or related code in the pdtoolbox.special module. The module contains code that is...

Fatbox - Fault Analysis Toolbox

Thilo Wrona, Sascha Brune, Pauline Gayrin & Tim Hake
Fatbox - Fault Analysis Toolbox is a python module for the extraction and analysis of faults (and fractures) in raster data. We often observer faults in 2-D or 3-D raster data (e.g. geological maps, numerical models or seismic volumes), yet the extraction of these structures still requires large amounts of our time. The aim of this module is to reduce this time by providing a set of functions, which can perform many of the steps...

Stress Map of Great Britain and Ireland 2022

Andrew Kingdon, John Williams, Mark Fellgett, Naomi Rettelbach & Oliver Heidbach
Stress maps show the orientation of the current maximum horizontal stress (SHmax) in the earth's crust. Assuming that the vertical stress (SV) is a principal stress, SHmax defines the orientation of the 3D stress tensor; the minimum horizontal stress Shmin is than perpendicular to SHmax. In stress maps SHmax orientations are represented as lines of different lengths. The length of the line is a measure of the quality of data and the symbol shows the...

Organochemical characterization of the mineralized Kupferschiefer in Spremberg, East Germany: Compositional and isotope data on hydrocarbons, biomarker and NSO compounds

Stefanie Poetz, Yang Liu, Joseph M. Magnall, Andrea Vieth-Hillebrand, Shengyu Yang, Michael Göthel, Sarah A. Gleeson, Hans-Martin Schulz, Cornelia Karger, Doreen Noack, Kristin Günther, Anke Kaminsky & Heike Rothe
Organic matter (OM) is known to be an important reductant in sediment-hosted base metal deposits like the European Kupferschiefer. However, the precise nature of interactions between OM and hydrothermal fluids are still debated as well as how the interconnected reactions develop over geological timescales. This dataset provides for the first time bulk, compositional and stable isotope data of hydrocarbons, biomarkers and organonitrogen, -sulfur and-oxygen (NSO) compounds for the mineralized Kupferschiefer Spremberg-Graustein field in Eastern Germany...

Thermo-Compositional Model of Cratonic Lithosphere and Depth to Moho of Africa

Nils-Peter Finger, Mikhail K. Kaban, Magdala Tesauro, Walter D. Mooney & Maik Thomas
In Finger et al. (2022), we created consistent three-dimensional models in terms of temperature, density and composition of the upper mantle of the cratonic part of the African continent by combining seismic [Celli et al., 2020] and gravity [Förste et al., 2014] data with mineral physics constraints in an iterative integrated inversion approach [Kaban et al., 2014; Tesauro et al., 2014]. Further, we calculated a new model of depth to the Moho to correct the...

Dublin pilot test train experiment, phase 2

Meysam Rezaeifar & Christopher J. Bean
Geophysical section of Dublin institute for Advanced studies is a publicly funded (government) academic research organization that develop new methods for studying the earth. In this project we are trying to develop new environmentally friendly ways to monitoring ground integrity. The idea is to use ground vibrations from natural and man-made sources, that already exist in everyday life for monitoring ground integrity. Here we would like to see if ground vibrations made by passing trains...

“1-month seismological experiment on Etna, Italy in 2019" is a 1-month seismological experi-ment realized near the Pizzi Deneri Observatory on Etna, Italy, by Eva Eibl and Daniel Vollmer (University of Potsdam) in collaboration with Philippe Jousset from GFZ Potsdam Germany and Gilda Currenti and Graziano Larocca from INGV-OE, Italy. From August to September 2019, we recorded the volcano-seismic events accompanying the volcanic activity using a rotational sensor and a co-located seismometer. The aim of the...

AnyPetro - Universal parameter fitting tool for petrophysical laboratory data

Jana H. Börner & Volker Herdegen
AnyPetro is a Matlab-based, GUI-controlled software for adjusting the parameters of arbitrary and non-linear petrophysical models to laboratory data. A Gauss-Newton scheme is applied for the minimization of a damped least-squares objective function. Thereby the Jacobian matrix is calculated explicitely with the perturbation method. Data weighting, model parameter transformations and different regularizations are provided. The petrophysical model resp. the forward operator is introduced by the user in the form of a short text file. Example...

An empirical model of electron pitch angle distributions in the outer radiation belt based on Van Allen Probes data

Artem Smirnov, Yuri Shprits, Hayley Allison, Nikita Aseev, Alexander Drozdov, Peter Kollmann, Dedong Wang & Anthony Saikin
Here, we present an empirical model of the equatorial electron pitch angle distributions, based on the Magnetic Electron Ion Spectrometer (MagEIS) instrument aboard the Van Allen Probes. The model was created for energies from 37 keV up to 2.65 MeV. The model uses the solar wind dynamic pressure as a driving parameter and has a continuous dependence on Lm, magnetic local time and activity. It works for L-shells from 3.05 up around 5.95. For each...

Su Yong, Li Jiancheng, Zou Xiancai, Xu Xinyu, Wang Changqing, Yu Biao & Li Qiong
The new unconstrained GRACE monthly solution SWPU-GRACE2021 is recently developed with the dynamic approach. The reprocessed GRACE L1B RL03 data and de-aliasing product AOD1B RL06 are applied to compute SWPU-GRACE2021. The arc length is variable according to the L1B data quality, but the maximum is no more than 24 hours. The bias vector and scale matrix of the GRACE Accelerometer observation ACC1B product are estimable parameters. The data covers the period from April 2002 to...

Peter Makus & Christoph Sens-Schönfelder
Monitoring Velocity Changes using Ambient Seismic Noise SeisMIC (Seismological Monitoring using Interferometric Concepts) is a python software that emerged from the miic library. SeisMIC provides functionality to apply some concepts of seismic interferometry to different data of elastic waves. Its main use case is the monitoring of temporal changes in a mediums Green's Function (i.e., monitoring of temporal velocity changes). SeisMIC will handle the whole workflow to create velocity-change time-series including: Downloading raw data, Adaptable...
