Wasserpflanzengesellschaften und Moore in Uruguay
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 13; 1983)Im Nordosten von Uruguay wurden Wasserpflanzengesellschaften und Niedermoore untersucht. Flache Tümpel werden von Pflanzengesellschaften besiedelt, in denen Jussiaea repens, Nymphoides humboldtiana, Hydrocleis nymphoides ... -
Wasserrückhaltung in degenerierten Hochmooren mit der Torfdichtwand
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 48; 2018)Zur Renaturierung von Hochmooren werden seit langem neben Grabenstauen mit Holzbrettern oder Torfmaterial auch Verwallungen aus Torf errichtet, um das Moorwasser zurückzuhalten. Die aufgesetzten Wälle zeigten jedoch nicht ... -
Water Content of the Dehydration Melting Layer in the Topmost Lower Mantle
(Geophysical Research Letters, 2021-01-09)The water‐rich mantle transition zone and dry lower mantle suggest that a dehydration melting layer can form at the 660‐km depth boundary. However, the water content of the melting layer (CH2Omelt), which dominates its ... -
Water contents of nominally anhydrous orthopyroxenes from oceanic peridotites determined by SIMS and FTIR
(Mineralogy and Petrology, 2021-08-27)This study presents new secondary ion mass spectrometry (SIMS) reference materials (RMs) for measuring water contents in nominally anhydrous orthopyroxenes from upper mantle peridotites. The enstatitic reference orthopyroxenes ... -
Water dynamics at the urban soil-atmosphere interface—rainwater storage in paved surfaces and its dependence on rain event characteristics
(Journal of Soils and Sediments, 2020-08-28)Purpose: The surface store governs the rainwater partition, e.g., water storage and evaporation on paved surfaces, especially for low-intensity and low-sum rain events, which account for the greatest part of ... -
Water in garnet of garnetite (metarodingite) and eclogite from the Erzgebirge and the Lepontine Alps
(Journal of Metamorphic Geology, 2020)Little is known about water in nominally anhydrous minerals of orogenic garnet peridotite and enclosed metabasic rocks. This study is focused on peridotite-hosted eclogite and garnetite (metarodingite) from the Erzgebirge ... -
Water Isotopic Signature of Surface Snow Metamorphism in Antarctica
(Geophysical Research Letters, 2021-09-03)Water isotope ratios of ice cores are a key source of information on past temperatures. Through fractionation within the hydrological cycle, temperature is imprinted in the water isotopic composition of snowfalls. However, ... -
Water Remediation by Metallic Iron: Much Ado About Nothing - As Profitless as Water in a Sieve?
(CLEAN - Soil, Air, Water, 2014) -
Water resource assessment of the TintinaraCoonalpyn Prescribed Wells Area
(Department of Water, Land and Biodiversity Conservatio, Adelaide, SA2002)This report provides an overview of the water resources for the TintinaraCoonalpyn PWA (TCPWA) and includes: A general assessment of the groundwater resources for each of the aquifers in the PWA. A description (for both ... -
Water scarcity and oil palm expansion: social views and environmental processes
(Ecology and Society, 2016)Conversions of natural ecosystems, e.g., from rain forests to managed plantations, result in significant changes in the hydrological cycle including periodic water scarcity. In Indonesia, large areas of forest were lost ... -
Water Solubility in Fe‐Bearing Wadsleyite at Mantle Transition Zone Temperatures
(Geophysical Research Letters, 2021-05-03)Wadsleyite can store significant amounts of H2O in its crystal structure as hydroxyl. However, H2O solubility in Fe‐bearing wadsleyite remains poorly constrained at mantle transition zone temperatures. Previous studies ... -
Water temperature control on CO2 flux and evaporation over a subtropical seagrass meadow revealed by atmospheric eddy covariance
(Limnology and Oceanography, 2020-10-08)Subtropical seagrass meadows play a major role in the coastal carbon cycle, but the nature of air–water CO2 exchanges over these ecosystems is still poorly understood. The complex physical forcing of air–water exchange in ... -
Water transport and tracer mixing in volcanic ash soils at a tropical hillslope: A wet layered sloping sponge
(Hydrological Processes, 2020)Andosol soils formed in volcanic ash provide key hydrological services in montane environments. To unravel the subsurface water transport and tracer mixing in these soils we conducted a detailed characterization of soil ... -
Water vapor in the tropical upper troposphere - on the influence of deep convection
(Univ. Köln, 2002)Wasserdampf ist eines der wichtigsten atmosphärischen Spurengase. Sein Einfluss auf das Klima, die Chemie und den Energiehaushalt ist bedeutend. Von besonderem Interesse ist dabei die Wasserdampfverteilung in der oberen ... -
Waterpower romance: the cultural myth of dying watermills in German hydro-narratives around 1900
(Water History, 2020-07-23)Even in the twenty-first century, myths of preindustrial forms of energy utilization are woven around watermills, waterwheels, and traditional millscapes. Along German watercourses, many grinding shops and hammer mills ... -
Wavefield methods to analyze passive ocean bottom seismic data - application to the Tyrrhenian sea
(Univ. Hamburg, 2006)In this study different full waveform techniques was developed for the investigation of seismic ocean bottom single station data. These techniques were applied to data obtained in a pilot ocean bottom experiment in the ... -
