Bacterial and archaeal lipids trace chemo(auto)trophy along the redoxcline in Vancouver Island fjords
; ; ; ; (Geobiology, 2021-05-07)
Abstract Marine oxygen minimum zones play a crucial role in the global oceanic carbon, nitrogen, and sulfur cycles as they harbor microbial communities that are adapted to the water column chemistry and redox zonation, and ... -
Bacterial Stern layer diffusion: experimental determination with spectral induced polarization and sensitivity to nitrite toxicity
; Smeaton, Christina M.; Furman, Alex; Atekwana, Estella A.; Rezanezhad, Fereidoun; (Near Surface Geophysics, 2019-08-07)
Spectral induced polarization signatures have been used as proxies for microbial abundance in subsurface environments, by taking advantage of the charged properties of microbial cell membranes. The method's applicability, ... -

Baseline Vector Repeatability at the Sub‐Millimeter Level Enabled by Radio Interferometer Phase Delays of Intra‐Site Baselines
; ; ; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Solid Earth, 2023-03-17)
We report the results of position ties for short baselines at eight geodetic sites based on phase delays that are extracted from global geodetic very‐long‐baseline interferometry (VLBI) observations rather than dedicated ... -
Basin‐scale estimates of greenhouse gas emissions from the Mara River, Kenya: Importance of discharge, stream size, and land use/land cover
; ; ; ; ; (Limnology and Oceanography, 2022-06-23)
Greenhouse gas fluxes (CO2, CH4, and N2O) from African streams and rivers are under‐represented in global datasets, resulting in uncertainties in their contributions to regional and global budgets. We conducted year‐long ... -

Bathymetric Control on Borchgrevink and Roi Baudouin Ice Shelves in East Antarctica
; ; ; ; (Journal of Geophysical Research: Earth Surface, 2021-10-07)
The stability of ice shelves and drainage of ice sheets they buttress is largely determined by melting at their atmospheric and oceanic interfaces. Subglacial bathymetry can impact ice shelf stability because it influences ... -
Bathymetry Beneath Ice Shelves of Western Dronning Maud Land, East Antarctica, and Implications on Ice Shelf Stability
; ; ; Smith, Emma Clare; (Geophysical Research Letters, 2020-06-13)
Antarctica's ice shelves play a key role in stabilizing the ice streams that feed them. Since basal melting largely depends on ice‐ocean interactions, it is vital to attain consistent bathymetry models to estimate water ... -
Bau und Entstehung der Alpen
(Verlag von Gebrüder Borntraeger, Berlin, 1923)Es wird hier der Versuch gemacht, die wesentlichen neuen Erfahrungen über den Bau und Entstehung der Alpen zusammenzufassen. Im Laufe von 12 Sommern habe ich Gelegenheit gehabt, die Alpen vom Simplon bis in die Karpathen, ... -
Bayesian Calibration and Sensitivity Analysis for a Karst Aquifer Model Using Active Subspaces
; ; ; ; (Water Resources Research, 2019)
In this article, we perform a parameter study for a recently developed karst hydrological model. The study consists of a high-dimensional Bayesian inverse problem and a global sensitivity analysis. For the first time in ... -
Bayesian Calibration and Validation of a Large‐Scale and Time‐Demanding Sediment Transport Model
; ; ; ; ; (Water Resources Research, 2020-07-24)
This study suggests a stochastic Bayesian approach for calibrating and validating morphodynamic sediment transport models and for quantifying parametric uncertainties in order to alleviate limitations of conventional ... -
Bayesian Calibration Points to Misconceptions in Three‐Dimensional Hydrodynamic Reservoir Modeling
; ; ; ; ; ; ; (Water Resources Research, 2023-03-02)
Three‐dimensional (3d) numerical models are state‐of‐the‐art for investigating complex hydrodynamic flow patterns in reservoirs and lakes. Such full‐complexity models are computationally demanding and their calibration is ... -
Bayesian geomorphology
(Earth Surface Processes and Landforms, 2020)
The rapidly growing amount and diversity of data are confronting us more than ever with the need to make informed predictions under uncertainty. The adverse impacts of climate change and natural hazards also motivate our ... -
Bayesian Hierarchical Modeling of Nitrate Concentration in a Forest Stream Affected by Large‐Scale Forest Dieback
; Senf, Cornelius; ; Krueger, Tobias (Water Resources Research, 2021-02-23)
The ecosystem function of vegetation to attenuate export of nutrients is of substantial importance for securing water quality. This ecosystem function is at risk of deterioration due to an increasing risk of large‐scale ... -
Bayesian Quantification and Reduction of Uncertainties in 3D Geomechanical‐Numerical Models
; (Journal of Geophysical Research: Solid Earth, 2022-12-29)
The distance to failure of the upper crustal rock in the prevalent stress field is of importance to better understand fault reactivation by natural and induced processes as well as to plan and manage georeservoirs. In ... -
Beamforming of Rayleigh and Love Waves in the Course of Atlantic Cyclones
;; (Journal of Geophysical Research: Solid Earth, 2023-02-21)
The main sources of the ambient seismic wavefield in the microseismic frequency band (peaking in the ∼0.04–0.5 Hz range) are earth's oceans, namely the wind‐driven surface gravity waves (SGW) that couple oscillations into ... -
