The Dom João de Castro seamount in the Hirondelle Basin (Azores) is a central volcano on the ultraslow diverging Terceira Rift axis. The combination of structural and geochemical data provides insights into the evolution ... -
Hydrological modelling for assessing spatio‐temporal groundwater recharge variations in the water‐stressed Amathole Water Supply System, Eastern Cape, South Africa
(Hydrological Processes, 2021-06-23)Abstract To increase the resilience of regional water supply systems in South Africa in the face of anticipated climatic changes and a constant increase in water demand, water supply sources require diversification. Many ... -
Seismic Velocity Variations in a 3D Martian Mantle: Implications for the InSight Measurements
Plesa, A.‐C.;; ; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Planets, 2021-06-17)
We use a large data set of 3D thermal evolution models to predict the distribution of present‐day seismic velocities in the Martian interior. Our models show a difference between maximum and minimum S wave velocity of up ... -
Migration of Arc Magmatism Above Mantle Wedge Diapirs With Variable Sediment Contribution in the Aegean
(Geochemistry, Geophysics, Geosystems, 2021-06-17)Compiled data show the age progression of magmatic centers along the two approximately linear profiles from NE Greece and NW Turkey to the South Aegean Volcanic Arc. The age progression reveals the southwestward migration ... -
Polar Stratospheric Clouds: Satellite Observations, Processes, and Role in Ozone Depletion
(Reviews of Geophysics, 2021-06-10)Polar stratospheric clouds (PSCs) play important roles in stratospheric ozone depletion during winter and spring at high latitudes (e.g., the Antarctic ozone hole). PSC particles provide sites for heterogeneous reactions ... -
Predicting Geothermal Heat Flow in Antarctica With a Machine Learning Approach
; (Journal of Geophysical Research: Solid Earth, 2021-06-10)
We present a machine learning approach to statistically derive geothermal heat flow (GHF) for Antarctica. The adopted approach estimates GHF from multiple geophysical and geological data sets, assuming that GHF is substantially ... -
Modelling the structural variation of quartz and germanium dioxide with temperature by means of transformed crystallographic data
(Acta Crystallographica Section B, 2021-05-27)The pseudocubic (PC) parameterization of O4 tetrahedra [Reifenberg & Thomas (2018). Acta Cryst. B74, 165–181] is applied to quartz (SiO2) and its structural analogue germanium dioxide (GeO2). In α‐quartz and GeO2, the ... -
Role of the Tropical Atlantic for the Interhemispheric Heat Transport During the Last Deglaciation
; ; ; ; ; (Paleoceanography and Paleoclimatology, 2021-05-22)
During the last deglaciation abrupt millennial‐scale perturbations of the Atlantic Meridional Overturning Circulation massively altered the interhemispheric heat distribution affecting, for example, continental ice volume ... -
The Impact of Solar Activity on Forecasting the Upper Atmosphere via Assimilation of Electron Density Data
; ; ; (Space Weather, 2021-05-20)
This study presents a comprehensive comparison of the impact of solar activity on forecasting the upper atmosphere through assimilation of radio occultation (RO)‐derived electron density (Ne) into a physics‐based model ... -
Sulfide Dissolution and Awaruite Formation in Continental Serpentinization Environments and Its Implications to Supporting Life
; Vrijmoed, J. C.; Engelmann, J. M.; ; Wiechert, U.; Rohne, R.; (Journal of Geophysical Research: Solid Earth, 2021-05-20)
Serpentinization environments are key locations that support microbial communities by the abiogenic formation of reduced species associated with peridotite alteration. Here we studied partially serpentinized peridotites ... -
Subsurface Moisture Regulates Himalayan Groundwater Storage and Discharge
; ; Sens‐Schönfelder, C.; ; Baidya, K. P.; ; (AGU Advances, 2021-05-18)
Through the release of groundwater, most mountain rivers run year‐round despite their small catchments and sporadic precipitation. This makes mountain ranges important sources of reliable freshwater for downstream populations ... -
