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 ... -
Response of large benthic foraminifera to climate and local changes: Implications for future carbonate production
; Reymond, Claire E.; ; Doo, Steve; Schmidt, Christiane; ; Westphal, Hildegard (Sedimentology, 2021-05-18)
Large benthic foraminifera are major carbonate components in tropical carbonate platforms, important carbonate producers, stratigraphic tools and powerful bioindicators (proxies) of environmental change. The application ... -
Cable reverberations during wireline distributed acoustic sensing measurements: their nature and methods for elimination
; Stiller, Manfred; ; ; (Geophysical Prospecting, 2021-05-16)
The application of distributed acoustic sensing in borehole measurements allows for the use of fibre optic cables to measure strain. This is more efficient in terms of time and costs compared with the deploying of conventional ... -
A multi‐criteria decision‐making approach for assembling optimal powertrain technology portfolios in low GHG emission environments
; ; (Journal of Industrial Ecology, 2021-05-13)
Environmental regulations force car manufacturers to renew the powertrain technology portfolio offered to the customer to comply with greenhouse gas (GHG) emission targets. In turn, automotive companies face the task of ... -
Capillary, Film, and Vapor Flow in Transient Bare Soil Evaporation (1): Identifiability Analysis of Hydraulic Conductivity in the Medium to Dry Moisture Range
; ; ; (Water Resources Research, 2021-05-13)
Evaporation experiments are frequently used to determine soil hydraulic properties. We simulated laboratory evaporation experiments with a coupled water, vapor, and heat flow model which includes the surface energy balance. ... -
Capillary, Film, and Vapor Flow in Transient Bare Soil Evaporation (2): Experimental Identification of Hydraulic Conductivity in the Medium to Dry Moisture Range
; ; (Water Resources Research, 2021-05-13)
Bare‐soil evaporation involves coupled flow of liquid water, water vapor, and heat. As evaporation results in non‐isothermal conditions in the soil, the temperature dependence of transport properties and thermal fluxes of ... -
Contextualizing land‐use and land‐cover change with local knowledge: A case study from Pokot Central, Kenya
Petersen, Maike; Bergmann, Christoph; Roden, Paul; (Land Degradation & Development, 2021-05-12)
Rural communities in the drylands of sub‐Saharan Africa (SSA) derive their livelihoods primarily from their natural resource base. Unprecedented changes in these environments over the past few decades are likely to intensify ... -
Bryozoan‐rich stromatolites (bryostromatolites) from the Silurian of Gotland and their relation to climate‐related perturbations of the global carbon cycle
; Munnecke, Axel; Ernst, Andrej (Sedimentology, 2021-05-12)
Bryozoan–stromatolite associations (bryostromatolites) formed conspicuous reef structures throughout the Sheinwoodian (Wenlock) to Ludfordian (Ludlow) stratigraphy on Gotland but have not been described so far. They are ... -
Zircon and Melt Extraction From a Long‐Lived and Vertically Extensive Magma System Underneath Ilopango Caldera (El Salvador)
; ; ; Schindlbeck‐Belo, J. C.; Hernández, W.; Sims, K. W. W.; ; ; ; Wang, K.‐L.; Lee, H.‐Y.; Trumbull, R. B. (Geochemistry, Geophysics, Geosystems, 2021-05-12)
The Tierra Blanca (TB) eruptive suite comprises the last four major eruptions of Ilopango caldera in El Salvador (≤45 ka), including the youngest Tierra Blanca Joven eruption (TBJ; ∼106 km3): the most voluminous event ... -
Upscaling Sediment‐Flux‐Dependent Fluvial Bedrock Incision to Long Timescales
(Journal of Geophysical Research: Earth Surface, 2021-05-12)
Fluvial bedrock incision is driven by the impact of moving bedload particles. Mechanistic, sediment‐flux‐dependent incision models have been proposed, but the stream power incision model (SPIM) is frequently used to model ... -
