Brackish water algal reefs – facies analysis as a tool to identify palaeoenvironmental variations in Miocene deposits (Mainz‐Weisenau, Germany)
; Knoblach, Julia; (Geological Journal, 2021-01-04)
Brackish‐water carbonates are far less studied than their marine or limnic counterparts. However, their association with few, specialized species enables the documentation of fine‐scale changes in the depositional environment. ... -
Bridging the Gap Between Biofuels and Biodiversity Through Monetizing Environmental Services of Miscanthus Cultivation
; ; ; ; ; ; ; van Eupen, Michiel; ; (Earth's Future, 2020)
Carbon neutrality in the transport sector is a key challenge for the growing bioeconomy as the share of biofuels has stagnated over the past decade. This can be attributed to basic economics and a lack of a robust market ... -

Brittle anisotropic fracture propagation in quartz sandstone: insights from phase-field simulations
; ; ; ; ; (Computational Geosciences, 2020-04-19)
We developed a generalized multiphase-field modeling framework for addressing the problem of brittle fracture propagation in quartz sandstones at microscopic length scale. Within this numerical approach, the grain boundaries ... -
Brittle Deformation of Carbonated Peridotite—Insights From Listvenites of the Samail Ophiolite (Oman Drilling Project Hole BT1B)
; ; ; ; Manning, Craig E.; Kelemen, Peter B.; ; Jesus, Ana P.; ; and the Oman Drilling Project Phase 1 Science Team (Journal of Geophysical Research: Solid Earth, 2020)
Hole BT1B of the Oman Drilling Project provides a continuous sampling from listvenite into the metamorphic sole that preserves the deformation, hydration, and carbonation processes of oceanic mantle peridotite at the base ... -
Brittle-Ductile Deformation and Tensile Rupture of Dome Lava During Inflation at Santiaguito, Guatemala
; ; ; ; ; ; ; (Journal of Geophysical Research: Solid Earth, 2019)
Gas-and-ash explosions at the Santiaguito dome complex, Guatemala, commonly occur through arcuate fractures, following a 5- to 6-min period of inflation observed in long-period seismic signals. Observation of active faults ... -
Broad Consistency Between Observed and Simulated Trends in Sea Surface Temperature Patterns
; ; (Geophysical Research Letters, 2020)
Using seven single-model ensembles and the two multimodel ensembles CMIP5 and CMIP6, we show that observed and simulated trends in sea surface temperature (SST) patterns are globally consistent when accounting for internal ... -
Broadband IF circuits for superconductor isolator superconductor (SIS) mixers for the Heterodyne Instrument for the far infrared on the Herschel Space Observatory and for sideband separating mixers
(Univ. Köln, 2007)This thesis describes the development and manufacturing of the IF circuits for two different heterodyne receivers used for sub-mm radio astronomy. The first project is the broadband 4-8 GHz IF circuitry for the mixer units ... -
Bromeliad tanks are unique habitats for microbial communities involved in methane turnover
Brandt, Franziska B.;; (Springer Verlag2016-07-23)
The results indicate that every bromeliad tank is a unique island with respect to its resident microbial community. The presence of methanogens and active methanotrophs in all tank slurries further indicates the potential ... -
Bryozoan‐rich stromatolites (bryostromatolites) from the Silurian of Gotland and their relation to climate‐related perturbations of the global carbon cycle
; ; (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 ... -
Bt-Horizonte als Interglazial-Zeiger in den humiden Mittelbreiten: Bildung, Mikromorphologie, Kriterien
(E&G – Quaternary Science Journal; Vol.50, No. 1)Die Untersuchung wird auf die humiden Mittelbreiten begrenzt, wo „Interglazial" durch die Rückwanderung temperierter Laubwälder definierbar ist. Auf die Frage, welche Bodentypen oder Horizonte sicher einem Interglazial ... -
Building stone quarries: resource evaluation by block modelling and unmanned aerial photogrammetric surveys
(Environmental Earth Sciences, 2021-12-18)The production of building stones shown an exponential growth in last decades as consequences of the demand and developments in the extraction and processing techniques. From the several conditioning factors affecting this ... -
