Thermo-compositional models of the West Gondwana cratons

Nils-Peter Finger , Mikhail K. Kaban , Magdala Tesauro , Walter D. Mooney & Maik Thomas
When Western Gondwana broke apart into the South American and African continents ca.120 Ma ago, some of its cratons were broken apart as well. Following the isopycnic hypothesis, their long-term stability and often neutral to positive buoyancy can be explained by the counteracting effects of cooling (density increase) and iron depletion (density decrease). To separate these effects, we created the presented models following an iterative integrated approach using mainly seismic and gravity data. In the...

Millennial variability, hydrological and limnological changes during MIS3-2 in Lake Petén Itzá, Guatemala

Rodrigo Martinez-Abarca, Michelle Abstein , Philipp Hoelzmann , Thorsten Bauersachs , Liseth Pérez , Mona Stockhecke , Sergio Cohuo Duran & Antje Schwalb
Heinrich Stadials and Greenland Interstadials are abrupt climate variations that are observed in the Northern Hemisphere throughout Marine Isotopic Stages (MIS) 3-2. Lake Petén Itzá, northern Guatemala, is a key site for paleoclimate investigations due to its sensitivity to changes in climate forcing such as the Intertropical Convergence Zone (ITCZ) and the Atlantic Meridional Overturning Circulation (AMOC). In this study, we reconstructed the hydrology and limnology of Lake Petén Itzá during MIS3-2 based on geochemical...

Tectonic accretion controls erosional cyclicity in the Himalaya

Dirk Scherler , Sanjay Kumar Mandal & Hella Wittmann
Indian Institute of Science Education and Research Kolkata, Mohanpur, India(3);The evolution of Earth’s climate over geological timescales is linked to surface erosion by weathering of silicate minerals and burial of organic carbon. However, methodological difficulties in reconstructing erosion rates through time and feedbacks among tectonics, climate, and erosion spurred an ongoing debate on mountain erosion sensitivity to tectonic and climate forcing. A key question is whether late Cenozoic climate cooling has increased global erosion rates...

Redox conditions during deserpentinization in western Elba Island, Italy.

Malte Kalter & Wolfgang Bach
The observation of oxidized arc melts has led to a discussion about the redox conditions during the dehydration reactions of serpentinites in subduction zones. The discussed range of oxygen fugacities (fO2) between+5 and -2 log units relatively to the QFM buffer allows sulfur to be present either as oxidized or reduced species. This work investigates the development of the fO2 with serpentines form the western part of the island Elba in Italy. We compared observations...

In-situ silicon isotopes in mantle wedge serpentinites - a new proxy for slab dehydration reactions

Sonja Geilert , Elmar Albers , Daniel A. Frick , Christian T. Hansen & Friedhelm von Blanckenburg
The Mariana forearc provides a unique natural laboratory to study slab dehydration in an active subduction zone by its deep-rooted mud volcanism. To test if mantle wedge serpentinites would record the source fluid composition and thus the dehydration reactions in the slab, we investigated silicon (Si) isotopic compositions (δ30Si) in serpentine veins by in-situ femtosecond laser ablation ICP mass spectrometry. Our samples were recovered during IODP Expedition 366 and originate from three mud volcanoes that...

Recent headwall deglaciation and retreat from cosmogenic 10Be in medial moraine debris of a Swiss valley glacier

Katharina Wetterauer, Dirk Scherler , Leif S. Anderson & Hella Wittmann
Debris-covered glaciers are fed from steep bedrock hillslopes that tower above the ice, so-called headwalls. Recent observations in high-alpine glacial environments suggest that rock walls are increasingly destabilized due to climate warming. An increase in debris delivery to glacier surfaces will modify glacial mass balances, as surface debris cover impacts on the melt behavior of the ice underneath. Consequently, we expect that the response of debris-covered glaciers to climate change is likely linked to how...

Comparing PTSD symptom networks in type I vs. type II trauma survivors

Mina Stefanovic, Thomas Ehring, Charlotte E. Wittekind, Birgit Kleim, Judith Rohde, Antje Krüger-Gottschalk, Christine Knaevelsrud, Heinrich Rau, Ingo Schäfer, Julia Schellong, Anne Dyer & Keisuke Takano
Background: Network analysis has gained increasing attention as a new framework to study complex associations between symptoms of post-traumatic stress disorder (PTSD). A number of studies have been published to investigate symptom networks on different sets of symptoms in different populations, and the findings have been inconsistent. Objective: We aimed to extend previous research by testing whether differences in PTSD symptom networks can be found in survivors of type I (single event; sudden and unexpected,...

Phenomenoconnectomics and the Neural Correlates of Altered Consciousness. An interview with Timo Torsten Schmidt by George Fejer

Timo Torsten Schmidt & George Fejer
In this interview, Timo Torsten Schmidt provides details about his efforts to compile a comprehensive database of all psychometric measures gathered from controlled experiments investigating altered states of consciousness induced by pharmacological and non-pharmacological methods. He also introduces the paradigm of Phenomenoconnectomics which aims to systematically investigate the phenomenology and functional connectivity of altered states of consciousness to identify commonalities and differences, to ultimately identify the necessary neuronal correlates of specific experiences as they occur...

The portal aims to increase the visibility and accessibility of the partner institutions’ infrastructures, data,...

A global rate of denudation from cosmogenic nuclides in the Earth’s largest rivers

Hella Wittmann , Marcus Oelze , Jerome Gaillardet , Eduardo Garzanti & Friedhelm von Blanckenburg
Cosmogenic nuclide analysis in sediment from the Earth’s largest rivers yields mean denudation rates of the sediment-producing areas that average out local variations commonly found in small rivers. Using this approach, we measured in situ cosmogenic 26Al and 10Be in sand of >50 large rivers over a range of climatic and tectonic regimes covering 32% of the Earth’s terrestrial surface. In 35% of the analyzed rivers, 26Al/10Be ratios are significantly lower than these nuclides´ surface-production-rate...

MEDICC2: whole-genome doubling aware copy-number phylogenies for cancer evolution.

Tom L Kaufmann, Marina Petkovic, Thomas BK Watkins, Emma C Colliver, Sofya Laskina, Nisha Thapa, Darlan C Minussi, Nicholas Navin, Charles Swanton, Peter Van Loo, Kerstin Haase, Maxime Tarabichi & Roland F Schwarz
Aneuploidy, chromosomal instability, somatic copy-number alterations, and whole-genome doubling (WGD) play key roles in cancer evolution and provide information for the complex task of phylogenetic inference. We present MEDICC2, a method for inferring evolutionary trees and WGD using haplotype-specific somatic copy-number alterations from single-cell or bulk data. MEDICC2 eschews simplifications such as the infinite sites assumption, allowing multiple mutations and parallel evolution, and does not treat adjacent loci as independent, allowing overlapping copy-number events. Using...
