Electromagnetic loop systems rely on the use of non-conductive materials near the sensor to minimize bias effects superimposed on measured data. For marine sensors, rigidity, compactness and ease of platform handling are ... -
Effects of mixing granular iron with sand on the efficiency of methylene blue discoloration
Miyajima, K.; (Chemical Engineering Journal, 2012)
The influence of granular sand on the efficiency of metallic iron (Fe0) for the discoloration of a methylene blue (MB) solution was investigated in the current work. The initial MB concentration was 10 mg L-1 and mass ... -
Effects of model calibration on hydrological and water resources management simulations under climate change in a semi-arid watershed
; ; ; ; (Climatic Change, 2020-11-18)
Semi-arid regions are known for erratic precipitation patterns with significant effects on the hydrological cycle and water resources availability. High temporal and spatial variation in precipitation causes large variability ... -
Effects of Reversal of Water Flow in an Arctic Floodplain River on Fluvial Emissions of CO2 and CH4
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2022-01-04)
When organic matter from thawed permafrost is released, the sources and sinks of greenhouse gases (GHGs), like carbon dioxide (CO2) and methane (CH4) in Arctic rivers will be influenced in the future. However, the temporal ... -
Effects of sample storage and shell orientation on LA-ICPMS trace element measurements on deep-sea mussels.
(Scientific reports, 2015)Geochemical markers are being increasingly applied to fundamental questions in population and community ecology in marine habitats because they allow inferences on individuals dispersal, but vital effects, small sample ... -
Effects of selected ligands on U (VI) immobilization by zerovalent iron

Effects of Temperature and Light on Methane Production of Widespread Marine Phytoplankton
; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2020)
Methane (CH4) production in the ocean surface mixed layer is a widespread but still largely unexplained phenomenon. In this context marine algae have recently been described as a possible source of CH4 in surface waters. ... -
Effects of the Hydrous Domain in the Mantle Wedge on Magma Formation and Mixing at the Northeast Lau Spreading Center, SW Pacific
; ; ; ; ; ; (Geochemistry, Geophysics, Geosystems, 2022-03-07)
Abundant volcanic activity occurs in the back‐arc region of the northern Tofua island arc where the Northeast Lau Spreading Center (NELSC) propagates southwards into older crust causing the formation of numerous seamounts ... -
Effects of the presence of pyrite and carbonate minerals on the kinetics of the uranium release from a natural rock
; Sonnefeld, J.; Merten, D.; Heinrichs, T. (Journal of radioanalytical and nuclear chemistry, 2006)
The influence of calcite, dolomite, pyrite and vaterite on the kinetics of uranium (U) release from a natural rock under relevant i.e. field conditions has been investigated. The time dependence of the U release has been ... -

Effects of Topography and Realistic Drag on the Southern Hemisphere Midlatitude Jet in a Dry Model
; (Journal of Advances in Modeling Earth Systems, 2020)
Climate models have substantial biases in the climatological latitude of the Southern Hemisphere eddy-driven jet and the time scale of annular mode variability and disagree on the jet response to climate change. Zonally ... -
Effects of water management on peatland water table and peatland subsidence
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 51; 2021)Drained peatlands are hotspots for carbon dioxide (CO2) and nitrous oxide (N2O) emissions. In Niedersachsen, 69 % of the peatland area is used for agriculture and is responsible for 11 % of the annual CO2 and N2O emissions. ... -
Effect‐Based Trigger Values for Mixtures of Chemicals in Surface Water Detected with In Vitro Bioassays
(Environmental Toxicology and Chemistry, 2021-01-13)Effect‐based trigger (EBT) values for in vitro bioassays are important for surface water quality monitoring because they define the threshold between acceptable and poor water quality. They have been derived for highly ... -
Efficiency and Accuracy of Micro-Macro Models for Mineral Dissolution
; ; ; (Water Resources Research, 2020)
Micro-macro models for dissolution processes are derived from detailed pore-scale models applying upscaling techniques. They consist of flow and transport equations at the scale of the porous medium (macroscale). Both ... -
