Effects of CO2 and Ocean Mixing on Miocene and Pliocene Temperature Gradients
; ; ; (Paleoceanography and Paleoclimatology, 2022-02-11)
Cenozoic climate changes have been linked to tectonic activity and variations in atmospheric CO2 concentrations. Here, we present Miocene and Pliocene sensitivity experiments performed with the climate model COSMOS. The ... -
Vertically Divergent Responses of SOC Decomposition to Soil Moisture in a Changing Climate
; ; ; ;; ; (Journal of Geophysical Research: Biogeosciences, 2022-01-31)
The role of soil moisture for organic matter decomposition rates remains poorly understood and underrepresented in Earth System Models (ESMs). We apply the Dual Arrhenius Michaelis‐Menten (DAMM) model to a selection of ESM ... -
New insights into particle transport in karst conduits using comparative tracer tests with natural sediments and solutes during low‐flow and high‐flow conditions
; ; (Hydrological Processes, 2022-01-23)
Colloidal particles are an important vector for the transport of contaminants in karst aquifers, characterized by a high degree of hydrologic variability. Understanding this heterogeneity and hydrogeological functioning ... -
Seasonal Differences in the Attenuation of Polar Trace Organics in the Hyporheic Zone of an Urban Stream
; ; ; ; (Water Resources Research, 2022-01-20)
Attenuation of trace organic compounds (TrOCs) in a river occurs to a large extent in its hyporheic zone. A major part of the attenuation of polar TrOCs is of microbial origin. As microbial activity depends on temperature ... -
Assessing Volcanic Controls on Miocene Climate Change
; ; ; (Geophysical Research Letters, 2022-01-18)
The Miocene period saw substantially warmer Earth surface temperatures than today, particularly during a period of global warming called the Mid Miocene Climatic Optimum (MMCO; ∼17–15 Ma). However, the long‐term drivers ... -
Investigating the Basal Shear Zone of the Submarine Tuaheni Landslide Complex, New Zealand: A Core‐Log‐Seismic Integration Study
; ; ; ; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Solid Earth, 2022-01-18)
Although submarine landslides have been studied for decades, a persistent challenge is the integration of diverse geoscientific datasets to characterize failure processes. We present a core‐log‐seismic integration study ... -
Uncertainty in Aerosol Optical Depth From Modern Aerosol‐Climate Models, Reanalyses, and Satellite Products
; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2022-01-18)
Despite the implication of aerosols for the radiation budget, there are persistent differences in data for the aerosol optical depth (τ) for 1998–2019. This study presents a comprehensive evaluation of the large‐scale ... -
Iron Exports From Catchments Are Constrained by Redox Status and Topography
; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-01-18)
Fe(III) hydroxides stabilize organic carbon (OC) and P in soils. Observations of rising stream Fe concentrations are controversially posited to result from a flushing of iron‐rich deeper soil layers or a decrease of competing ... -
The Goldilocks Zone in Cooling Demand: What Can We Do Better?
;; (Earth's Future, 2022-01-18)
The higher frequency and intensity of sustained heat events have increased the demand for cooling energy across the globe. Current estimates of summer‐time energy demand are primarily based on Cooling Degree Days (CDD), ... -
Blaubeuren, Cloppenburg, and Machtenstein—Three recently recognized H‐group chondrite finds in Germany with distinct terrestrial ages and weathering effects
; ; ; ; ; ; ; (Meteoritics & Planetary Science, 2022-01-17)
In the last 7 years, three meteorites (Blaubeuren, Cloppenburg, and Machtenstein) found in Germany were identified as chondrites. Two of these rocks had been recovered from the impact sites decades ago but were not considered ... -
Faulting and Magmatic Accretion Across the Overlapping Spreading Center Between Vance Segment and Axial South Rift, Juan de Fuca Ridge
; ; (Geochemistry, Geophysics, Geosystems, 2022-01-12)
Plate divergence along mid‐ocean ridges is accommodated through faulting and magmatic accretion, and, at overlapping spreading centers (OSC), is distributed across two curvilinear overlapping ridge axes. One‐meter resolution ... -
Rock Glacier Characteristics Under Semiarid Climate Conditions in the Western Nyainqêntanglha Range, Tibetan Plateau
; ; ; ; ; ; ; ; (Journal of Geophysical Research: Earth Surface, 2022-01-07)
Rock glaciers are receiving increased attention as a potential source of water and indicator of climate change in periglacial landscapes. They consist of an ice‐debris mixture, which creeps downslope. Although rock glaciers ... -
Effects of Reversal of Water Flow in an Arctic Floodplain River on Fluvial Emissions of CO2 and CH4
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2022-01-04)
When organic matter from thawed permafrost is released, the sources and sinks of greenhouse gases (GHGs), like carbon dioxide (CO2) and methane (CH4) in Arctic rivers will be influenced in the future. However, the temporal ... -
Feasibility of pXRF to evaluate chosen heavy metals in soil highly influenced by municipal waste disposal—A monitoring study of a former sewage farm
; ; ; (Land Degradation & Development, 2022-01-03)
Sewage disposal onto agricultural land may result in the high accumulation of organic wastes, which questions the applicability of typical elemental analysis used for the soil components. To monitor the contamination status ... -
