Dissolved organic matter concentration, molecular composition, and functional groups in contrasting management practices of peatlands
; ; ; (Journal of Environmental Quality, 2021-09-25)
About 91,300 ha of peatlands has been rewetted in western Europe since the mid‐1990s. Still, it is unknown how long‐term rewetting alters the dissolved organic matter (DOM) concentration, molecular composition, and functional ... -

We present high‐resolution profiles of dissolved, labile, and total particulate trace metals (TMs) on the Northeast Greenland shelf from GEOTRACES cruise GN05 in August 2016. Combined with radium isotopes, stable oxygen ... -
Distinct Mechanisms Underlying Interannual to Decadal Variability of Observed Salinity and Nutrient Concentration in the Northern North Sea
; Gouretski, Viktor; Hinrichs, Iris; (Journal of Geophysical Research: Oceans, 2020)
The influence of large-scale oceanic circulation on salinity in the northern North Sea has lead to the hypothesis that nutrient concentrations in this region are also driven by remote oceanic anomalies. Here, using a newly ... -
Distribution and palaeoecological indicator value of diatoms in Holocene coastal deposits of the southern North Sea (Lower Saxony, Germany)
(E&G – Quaternary Science Journal; Vol.54, No. 1)Die Entstehung der niedersächsischen Küstenlandschaften ist während der letzten 8000 Jahre eng mit Meeresspiegelfluktuationen verbunden, die Phasen von Meeresspiegelabsenkungen und -anstiegen ebenso umfassen wie ... -
Distribution and timing of Holocene and late Pleistocene glacier fluctuations in western Mongolia
; Klinge, Michael; Rother, Henrik; Hülle, Daniela (Annals of Glaciology, 2016)
Despite being a key location for paleoglaciological research in north-central Asia, with the largest number of modern and Pleistocene glaciers, and in the transition zone between the humid Russian Altai and dry Gobi ... -
Distribution and transportation pathways of marine particulate matter off Northwest Africa
(Univ. Bremen, 2004)Marine snow, underwater cameras, particle flux, aggregation, suspended particulate matter, particle transport. - This study focusses on the vertical distribution and transportation pathways of marine particles off NW-Africa ... -
Distribution of Temperature and Strength in the Central Andean Lithosphere and Its Relationship to Seismicity and Active Deformation
; ; ; ; (Journal of Geophysical Research: Solid Earth, 2021-05-11)
We present three‐dimensional (3D) models of the present‐day steady‐state conductive thermal field and strength distribution in the lithosphere beneath the Central Andes. Our primary objective was to investigate the influence ... -
Distribution of the Heavy Minerals in the Downwind Tephra Lobe of the May 18, 1980 Eruption of the Mount St. Helens (Washington, USA)
(E&G – Quaternary Science Journal; Vol.33, No. 1)Die stratigraphische Korrelation von vulkanischen Leithorizonten aufgrund ihrer Schwermineralzusammensetzung bringt Probleme mit sich, da die Frage, ob die Zusammensetzung im Verbreitungsgebiet konstant oder wechselnd ist, ... -
Distribution, drivers and population structure of the invasive alien snail Tarebia granifera in the Luvuvhu system, South Africa
;; ; ; ; ; (River Research and Applications, 2022-02-03)
Invasive alien species continue to spread and proliferate in waterways worldwide, but environmental drivers of invasion dynamics lack assessment. Knowledge gaps are pervasive in the Global South, where the frequent heavy ... -
Distributive justice and the global emissions budget
; ; (Wiley Interdisciplinary Reviews: Climate Change, 2023-05-25)
Abstract In order not to significantly overshoot maximum levels of warming like the 1.5 and 2°C ...

Diurnal Pumped‐Storage Operation Minimizes Methane Ebullition Fluxes From Hydropower Reservoirs
; ; (Water Resources Research, 2020-12-04)
Hydropower is considered green energy and promoted to reduce greenhouse warming. However, hydropower is typically generated using reservoirs and reservoirs are known to emit substantial amounts of the greenhouse gas methane ... -
Diurnal to annual variability of the atmospheric boundary layer over West Africa - a comprehensive view by remote sensing observations
(Univ. Köln, 2009)
Weather and climate in West Africa are determined by the pronounced contrast between tropical, moist air masses over the Gulf of Guinea in the south and the dry desert climate over the Sahara in the north. The sharp border ... -
Diversity and composition of herbaceous angiosperms along gradients of elevation and forest-use intensity.
(PloS one, 2017)Terrestrial herbs are important elements of tropical forests; however, there is a lack of research on their diversity patterns and how they respond to different intensities of forest-use. The aim of this study was to analyze ... -
Diversity patterns and palaeoecology of benthic communities of the Kanosh Formation (Pogonip Group, Utah, western USA)

The Dapingian to Darriwilian Kanosh Formation is one of the most fossiliferous units of the Pogonip Group (Great Basin, western US). It records a critical phase of the so-called Great Ordovician Biodiversification Event ... -
Diversity patterns of Middle Permian gastropod assemblages from the Tak Fa Formation, Central Thailand
; ; (Palaeobiodiversity and Palaeoenvironments, 2021-05-07)
Middle Permian marine invertebrate assemblages from Central Thailand are strongly dominated by gastropods. Two gastropod assemblages from the Tak Fa Limestone at Khao Noi and Khao Chao Thong of the Nakhon Sawan area are ... -
Do earthworms (D. veneta) influence plant-available water in technogenic soil-like substrate from bricks and compost?
(Journal of Soils and Sediments, 2020-09-15)Purpose: Topsoil and peat are often taken from intact rural ecosystems to supply the urban demand for fertile soils and soil-like substrates. One way of reducing this exploitation is to recycle suitable urban ... -
