Impact of Spreading Rate and Age‐Offset on Oceanic Transform Fault Morphology
; ; (Geophysical Research Letters, 2022-01-24)
Oceanic transform faults (OTFs) are an inherent part of seafloor spreading and plate tectonics, whereas the process controlling their morphology remains enigmatic. Here, we systematically quantify variations in transform ... -
Impact of the Juan Fernandez Ridge on the Pampean Flat Subduction Inferred From Full Waveform Inversion

A new seismic model for crust and upper mantle of the south Central Andes is derived from full waveform inversion, covering the Pampean flat subduction and adjacent Payenia steep subduction segments. Focused crustal ... -
Impact of Tropospheric Ties on UT1‐UTC in GNSS and VLBI Integrated Solution of Intensive Sessions
; ; ; ; ; (Journal of Geophysical Research: Solid Earth, 2022-11-11)
Very Long Baseline Interferometry (VLBI) intensive (INT) sessions are critical for the rapid determination and densification of Universal Time 1‐Coordinate Universal Time (UT1‐UTC), which plays an important role in satellite ... -
Impact of Volcanic Aerosols on the Hydrology of the Asian Monsoon and Westerlies‐Dominated Subregions: Comparison of Proxy and Multimodel Ensemble Means
; ; ; (Journal of Geophysical Research: Atmospheres, 2020-09-11)
Proxy‐model comparisons show large discrepancies in the impact of volcanic aerosols on the hydrology of the Asian monsoon region (AMR). This was mostly imputed to uncertainties arising from the use of a single model in ... -
Impact-Induced Porosity and Microfracturing at the Chicxulub Impact Structure
; ; ; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Planets, 2019)
Porosity and its distribution in impact craters has an important effect on the petrophysical properties of impactites: seismic wave speeds and reflectivity, rock permeability, strength, and density. These properties are ... -
Impacts of a weir and power station on downstream migrating Atlantic salmon smolts in a German river
; ; ;; ; ; ; ; (River Research and Applications, 2020)
Weirs are barriers built across rivers for a wide range of other purposes than hydropower production. Like hydropower installations, weirs can negatively impact fish migrations. Downstream migration and mortality of Atlantic ... -
Impacts of Drying and Rewetting on the Radiocarbon Signature of Respired CO2 and Implications for Incubating Archived Soils
; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2021-09-14)
The radiocarbon signature of respired CO2 (∆14C‐CO2) measured in laboratory soil incubations integrates contributions from soil carbon pools with a wide range of ages, making it a powerful model constraint. Incubating ... -

; ; ; ; (Water Resources Research, 2022-03-24)
Subsurface flows, particularly hyporheic exchange fluxes, driven by streambed topography, permeability, channel gradient and dynamic flow conditions provide prominent ecological services such as nitrate removal from streams ... -
Impacts of the Assimilation of Satellite Sea Surface Temperature Data on Volume and Heat Budget Estimates for the North Sea
; ; ; (Journal of Geophysical Research: Oceans, 2021-05-03)
Mechanisms controlling the heat budget of the North Sea are investigated based on a combination of satellite sea surface temperature measurements and numerical model simulations. Lateral heat fluxes across the shelf edge ... -
Impacts of the Desiccation of the Aral Sea on the Central Asian Dust Life‐Cycle
; ; (Journal of Geophysical Research: Atmospheres, 2022-11-06)
The formation of the Aralkum (Aral Desert), following the severe desiccation of the former Aral Sea since the 1960s, has created what may be regarded as one of the world's most significant anthropogenic dust sources. In ... -
Impact‐Based Forecasting for Pluvial Floods
