A framework for drinking water basin protection
(Water and Environment Journal, 2021-06-02)
Many countries have applied many measures, including preventing inappropriate activities in areas where drinking water is abstracted to protect drinking water resources. However, reaching good water quality based on human ... -
A global-scale analysis of water storage dynamics of inland wetlands: Quantifying the impacts of human water use and man-made reservoirs as well as the unavoidable and avoidable impacts of climate change
; ; ; (Ecohydrology, 2019)
Wetlands such as bogs, swamps, or freshwater marshes are hotspots of biodiversity. For 5.1 million km2 of inland wetlands, the dynamics of area and water storage, which strongly impact biodiversity and ecosystem services, ... -
Abrupt Climate and Weather Changes Across Time Scales
; ; ; ; (Paleoceanography and Paleoclimatology, 2020)
The past provides evidence of abrupt climate shifts and changes in the frequency of climate and weather extremes. We explore the nonlinear response to orbital forcing and then consider climate millennial variability down ... -
Analysis of future changes in meteorological drought patterns in Fulda, Germany
; Ivanov, Martin; ; Luterbacher, Jürg; (International Journal of Climatology, 2020)
Meteorological droughts have large impacts on society and the environment. A better understanding and quantification of their occurrences can be highly relevant for the development of proper climate change mitigation, ... -
Arctic Ocean Surface Energy Flux and the Cold Halocline in Future Climate Projections
; ; (Journal of Geophysical Research: Oceans, 2020)
Ocean heat transport is often thought to play a secondary role for Arctic surface warming in part because warm water which flows northward is prevented from reaching the surface by a cold and stable halocline layer. However, ... -
Assessing vertical diffusion in a stratified lake using a three-dimensional hydrodynamic model
;; ; ; ; ; (Hydrological Processes, 2019)
Vertical turbulent diffusivity (Kz), which can be estimated from water temperature, is a key factor in the evolution of water quality in lentic waters. In this study, we analysed the capability of a three-dimensional ... -
Changing Salinity Gradients in the Baltic Sea As a Consequence of Altered Freshwater Budgets
; ; (Geophysical Research Letters, 2019)
Climate change is expected to enhance the hydrological cycle in northern latitudes reducing the salinity in the Baltic Sea, a land-locked marginal sea with a large catchment area located in northern Europe. With the help ... -
Chemical Evolution of the Exceptional Arctic Stratospheric Winter 2019/2020 Compared to Previous Arctic and Antarctic Winters
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2021-09-21)
The winter 2019/2020 showed the lowest ozone mixing ratios ever observed in the Arctic winter stratosphere. It was the coldest Arctic stratospheric winter on record and was characterized by an unusually strong and long‐lasting ... -
Corporate carbon performance data: Quo vadis?
; ; (Journal of Industrial Ecology, 2020)
Corporate carbon performance (CCP) has become a central topic in political, financial, and academic domains. At the same time, several characteristics of CCP data, including comparability and consistency, remain unresolved. ... -
Desert Soils in Lower Wadi Howar - Evidence of climate change and human impact during the Holocene
(Leidorf2007-08-30)The analysis of desert soils near archaeological sites allowed new insights in the environmental and living conditions of the early inhabitants of the Wadi Howar (NW Sudan) and their interactions with their environment. ... -
Does Export Production Measure Transient Changes of the Biological Carbon Pump's Feedback to the Atmosphere Under Global Warming?
; Kähler, P.; (Geophysical Research Letters, 2020-11-20)
In a widely‐held conception, the biological carbon pump (BCP) is equal to the export of organic matter out of the euphotic zone. Using global ocean‐atmosphere model experiments we show that the change in export production ... -
Exploring the Iron-Binding Potential of the Ocean Using a Combined pH and DOC Parameterization
; ; (Global Biogeochemical Cycles, 2020)
The major part of dissolved iron (DFe) in seawater is bound to organic matter, which prevents iron from adsorptive removal by sinking particles and essentially regulates the residence time of DFe and its availability for ... -
Grassland greening on the Mongolian Plateau despite higher grazing intensity
; Sun, Zhanli; Ren, Yanjun; Schierhorn, Florian; Müller, Daniel (Land Degradation & Development, 2020-10-01)
Changes in land management and climate alter vegetation dynamics, but the determinants of vegetation changes often remain elusive, especially in global drylands. Here we assess the determinants of grassland greenness on ... -
Guidelines for Studying Diverse Types of Compound Weather and Climate Events
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Earth's Future, 2021-11-10)
Compound weather and climate events are combinations of climate drivers and/or hazards that contribute to societal or environmental risk. Studying compound events often requires a multidisciplinary approach combining domain ... -
Holocene lake‐level evolution of Lake Tiefer See, NE Germany, caused by climate and land cover changes
; ; ; ; ; ; ; ; ; ; (Boreas, 2021-11-17)
Lake‐level reconstructions are a key tool in hydro‐climate reconstructions, based on the assumption that lake‐level changes primarily reflect climatic changes. Although it is known that land cover changes can affect ... -
Impacts of Drying and Rewetting on the Radiocarbon Signature of Respired CO2 and Implications for Incubating Archived Soils
; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2021-09-14)
The radiocarbon signature of respired CO2 (∆14C‐CO2) measured in laboratory soil incubations integrates contributions from soil carbon pools with a wide range of ages, making it a powerful model constraint. Incubating ... -
Joint Trends in Flood Magnitudes and Spatial Extents Across Europe
; ; ; ; (Geophysical Research Letters, 2020)
The magnitudes of river floods in Europe have been observed to change, but their alignment with changes in the spatial coverage or extent of individual floods has not been clear. We analyze flood magnitudes and extents for ... -
Kartographie als Klimaarchiv - Meereis im Norden, vom Eis verschlossene Schiffspassagen und verstoßende Gletscher - alte Karten dokumentieren die »Kleine Eiszeit«
(E&G – Quaternary Science Journal; Vol.55, No. 1)Im 15. Jh. weisen Tabulae modernae und Weltkarten lateinischer Ptolemäus-Ausgaben auf Meereis in Nordeuropa hin. Zu Beginn des 17. Jh. scheitert die Suche nach einer Nordwestpassage nach Asien. Das Mittelalterliche ... -
