Deciphering the Whisper of Volcanoes: Monitoring Velocity Changes at Kamchatka's Klyuchevskoy Group With Fluctuating Noise Fields
; ; ; ; ; (Journal of Geophysical Research: Solid Earth, 2023-03-30)
Volcanic inflation and deflation often precede eruptions and can lead to seismic velocity changes (dv/v $dv/v$) in the subsurface. Recently, interferometry on the coda of ambient noise‐cross‐correlation functions yielded ... -

Decoding the complex internal chemical structure of garnet porphyroblasts from the Zermatt area, Western Alps
; Weisenberger, Tobias Björn; Klemm, Oliver; Weber, Sebastian (Journal of Metamorphic Geology, 2019)
Garnet is a prototypical mineral in metamorphic rocks because it commonly preserves chemical and textural features that can be used for untangling its metamorphic development. Large garnet porphyroblasts may show extremely ... -
Decomposing Barotropic Transport Variability in a High-Resolution Model of the North Atlantic Ocean
; ; ; (Journal of Geophysical Research: Oceans, 2020)
A method using a linear shallow water model is presented for decomposing the temporal variability of the barotropic stream function in a high-resolution ocean model. The method is based on the vertically averaged momentum ... -
Decompression and Fracturing Caused by Magmatically Induced Thermal Stresses
; ; ; (Journal of Geophysical Research: Solid Earth, 2023-03-17)
Studies of host rock deformation around magmatic intrusions usually focus on the development of stresses directly related to the intrusion process. This is done either by considering an inflating region that represents the ... -
Deep Emulators for Differentiation, Forecasting, and Parametrization in Earth Science Simulators
; (Journal of Advances in Modeling Earth Systems, 2021-06-28)
To understand and predict large, complex, and chaotic systems, Earth scientists build simulators from physical laws. Simulators generalize better to new scenarios, require fewer tunable parameters, and are more interpretable ... -
Deep exploration using long-offset transient electromagnetics: interpretation of field data in time and frequency domain
; Yogeshwar, Pritam; Tezkan, Bülent; Hanstein, Tilman (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. ... -
Deep genetic divergences among Indo-Pacific populations of the coral reef sponge Leucetta chagosensis (Leucettidae): Founder effects, vicariance, or both? - Research article
; Epp, Laura S.; Macis, Luciana (BMC evolutionary biology, 2008)
Background: An increasing number of studies demonstrate that genetic differentiation and speciation in the sea occur over much smaller spatial scales than previously appreciated given the wide distribution range of many ... -

Deep Geothermal Energy for Lower Saxony (North Germany) – Combined Investigations of Geothermal Reservoir Characteristics
(Energy Procedia, 2014)For the economic success of a geothermal project the hydraulic properties and temperature of the geothermal reservoir are crucial. New methodologies in seismics, geoelectrics and reservoir geology are tested within the ... -
Deep Heat: Proxies, Miocene Ice, and an End in Sight for Paleoclimate Paradoxes?
(Paleoceanography and Paleoclimatology, 2021-03-16)
The mid Miocene represents an important target for paleoclimatic study because the atmospheric CO2 concentration ranged from near modern values to ∼800 ppm, while a large, dynamic Antarctic ice sheet was likely to have ... -
Deep Learning Based Cloud Cover Parameterization for ICON
; ; ; ; ; (Journal of Advances in Modeling Earth Systems, 2022-12-14)
A promising approach to improve cloud parameterizations within climate models and thus climate projections is to use deep learning in combination with training data from storm‐resolving model (SRM) simulations. The ICOsahedral ... -
Deepening the Late Quaternary's Deep Ocean Carbon Mysteries
(Geophysical Research Letters, 2022-07-06)
Changes to the carbon content of the deep ocean, the largest reservoir in the surficial carbon cycle, are capable of altering atmospheric carbon dioxide concentrations and thereby Earth's climate. While the role of the ... -
DeepLandforms: A Deep Learning Computer Vision Toolset Applied to a Prime Use Case for Mapping Planetary Skylights
; ; ; (Earth and Space Science, 2023-01-04)
Thematic map creation is a meticulous process that requires several steps to be accomplished regardless of the type of map to be produced, from data collection, through data exploitation and map publication in print, image, ... -
