Transport and Retention of Sulfidized Silver Nanoparticles in Porous Media: The Role of Air-Water Interfaces, Flow Velocity, and Natural Organic Matter
; ; ; (Water Resources Research, 2020)
The sulfidation and aging of silver nanoparticles (Ag-NPs) with natural organic matter (NOM) are major transformation processes along their pathway in wastewater treatment plants and surface waters. Although soils appear ... -
Transports and Pathways of the Tropical AMOC Return Flow From Argo Data and Shipboard Velocity Measurements
; ; ; (Journal of Geophysical Research: Oceans, 2022-02-05)
The upper‐ocean circulation of the tropical Atlantic is a complex superposition of thermohaline and wind‐driven flow components. The resulting zonally and vertically integrated upper‐ocean meridional flow is referred to ... -
Transposable Elements: From DNA Parasites to Architects of Metazoan Evolution
(Genes, 2012)One of the most unexpected insights that followed from the completion of the human genome a decade ago was that more than half of our DNA is derived from transposable elements (TEs). Due to advances in high throughput ... -
Traveltime based true amplitude migration
(Univ. Hamburg, 2002) -
Traveltime computation and migration in anisotropic media
(Univ. Hamburg, 2007)For seismic imaging of complex 3-D structures by e.g. prestack Kirchhoff depth migration large amounts of traveltime tables are required. This work provides a wavefront-oriented ray tracing technique for multi-valued ... -
Trees Talk Tremor—Wood Anatomy and δ13C Content Reveal Contrasting Tree‐Growth Responses to Earthquakes
; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2021-10-08)
Large earthquakes can increase the amount of water feeding stream flows, raise groundwater levels, and thus grant plant roots more access to water in water‐limited environments. We examine growth and photosynthetic responses ... -
Treibhausgasemissionen aus Mooren und Möglichkeiten der Verringerung
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Beiheft 5; 2015)Abstract: Peatlands are intensively exchanging greenhouse gases with the free atmosphere. Natural peatlands, mires, sequester carbon dioxide as carbon in the peat and emit methane. Peatlands under agriculture or forest are ... -
Trend- und Spektralanalysen von Grundwasserstandsganglinien und klimatologischen Reihen zur Ermittlung der Grundwasserneubildung in drei Gebieten von Berlin (West)
(Reimer, Berlin, 1978)Aus drei Gebieten von Berlin (West), die einen geologisch verschiedenen, aber jeweils ziemlich homogenen Aufbau besitzen, wurden ca. 60 Grundwasserstandsganglinien und klimatologische Datenreihen analysiert. Das Ziel ist ... -
Trends in AOD, Clouds, and Cloud Radiative Effects in Satellite Data and CMIP5 and CMIP6 Model Simulations Over Aerosol Source Regions
; (Geophysical Research Letters, 2020)
Several regions worldwide have seen significant trends in anthropogenic aerosol emissions during the period of detailed satellite observations since 2001. Over Europe (EUR) and North America (NAM) there were strong declines, ... -
Trennbruchversagen von Festgesteinen unter triaxialen Spannungsbedingungen
(Univ. Halle, 2007)Im Konturbereich einer untertägigen Auffahrung kommt dem Spannungsregime Extension aufgrund der Reduzierung des Spannungsanteils normal zur freien Oberfläche besondere Bedeutung zu. Die damit im Zusammenhang stehenden ... -
Trilobitenfunde am Lagergang vom Wasenbachtal (südwestliche Lahnmulde) - Neue Vertreter der Otarioninae Richter & Richter, 1926 aus den Rupbach-Schiefern des Nordbruchs
(Mainzer geowissenschaftliche Mitteilungen; 51. 2023)In einem längst stillgelegten Steinbruch im Wasenbachtal in der südwestlichen Lahnmulde (Rheinisches Schiefergebirge) haben die Übergangsschichten vom Unter- zum Mitteldevon in den Kontaktflächen eines Lagerganges ... -
TRIPLE – Ice Data Hub, Model-based Mission Support and Forefield Reconnaissance System
; ; ; ; ; ; ; ; ; ; ; ; (2021)
The ocean worlds of our Solar System, like Saturn's moon Enceladus and Jupiter's moon Europa are covered with ice. Recently, these icy moons gained further scientific interest, as they are attributed some potential to ... -
Triple‐Element Stable Isotope Analysis of Chloromethane Emitted by Royal Fern and Degraded by Club Moss

Tropical Continents Rainier Than Expected From Geometrical Constraints
; (AGU Advances, 2022-07-06)
Abundant rainfall over tropical land masses sustains rich ecosystems, a crucial source of biodiversity and sink of carbon. Here, we use two characteristics of the observed tropical precipitation distribution, its distinctive ... -
Tropical cyclone life cycle in a three‐dimensional numerical simulation
; ; (Quarterly Journal of the Royal Meteorological Society, 2021-08-16)
An idealized, three‐dimensional, numerical simulation of tropical cyclone evolution in a quiescent environment on an f‐plane is used to explore aspects of the cyclone's life cycle in the context of the rotating‐convection ... -
Tropical Expansion Driven by Poleward Advancing Midlatitude Meridional Temperature Gradients
; ; ; ; ; Liu, Jiping; (Journal of Geophysical Research: Atmospheres, 2020)
An abundance of evidence indicates that the tropics are expanding. Despite many attempts to decipher the cause, the underlying dynamical mechanism driving tropical expansion is still not entirely clear. Here, based on ... -
Tropical Instability Waves and Wind‐Forced Cross‐Equatorial Flow in the Central Atlantic Ocean
; ; ; ; ; (Geophysical Research Letters, 2022-09-29)
Based on velocity data from a long‐term moored observatory located at 0°N, 23°W we present evidence of a vertical asymmetry during the intraseasonal maxima of northward and southward upper‐ocean flow in the equatorial ... -
Tropical precipitation influencing boreal winter midlatitude blocking
; ; (Atmospheric Science Letters, 2019)
Recent studies using reanalysis data and complex models suggest that the Tropics influence midlatitude blocking. Here, the influence of tropical precipitation anomalies is investigated further using a dry dynamical model ...
