Analytical approach for modeling of multi well CO2 injection
(Elsevier, 2017-07-01)Disposal of carbon dioxide (CO2) into underground geological formations is considered a viable strategy for the mitigation of global warming. It aims to reduce greenhouse gases emitted from point sources such as power ... -
Anatexis of former arc magmatic rocks during oceanic subduction: A case study from the North Wulan gneiss complex
(Elsevier, 2018-09-01)Migmatites are widespread in the North Wulan gneiss complex from the South Qilian–North Qaidam orogenic belt, but their petrogenesis and ages are poorly constrained. Here, an integrated study of petrography, whole-rock ... -
An approach to improve direct runoff estimates and reduce uncertainty in the calculated groundwater component in water balances of large lakes
(Journal of Hydrology, 2015-10-30)Groundwater is important in the overall water budget of a lake because it affects the quantity and quality of surface water and the ecological health of the lake. The water balance equation is frequently used to estimate ... -
Atmospheric acidification of mineral aerosols: a source of bioavailable phosphorus for the oceans
(European Geosciences Union, 2011-07-01)Primary productivity of continental and marine ecosystems is often limited or co-limited by phosphorus. Deposition of atmospheric aerosols provides the major external source of phosphorus to marine surface waters. However, ... -
Automatic estimation of aquifer parameters using long-term water supply pumping and injection records
(Springer, 2016-09-01)Analyses are presented of long-term hydrographs perturbed by variable pumping/injection events in a confined aquifer at a municipal water-supply well field in the Region of Waterloo, Ontario (Canada). Such records are ... -
Behaviour of apatite during partial melting of metapelites and consequences for prograde suprasolidus monazite growth
(Elsevier, 2017-03-01)The suprasolidus behaviour of apatite and monazite is examined for an average metapelite composition using phase equilibria modelling coupled with solubility equations of these minerals. Both closed- and open-system scenarios ... -
Bioretention cells under cold climate conditions: Effects of freezing and thawing on water infiltration, soil structure, and nutrient removal
(Elsevier, 2019-02-01)Bioretention cells are a popular control strategy for stormwater volume and quality, but their efficiency for water infiltration and nutrient removal under cold climate conditions has been poorly studied. In this work, ... -
Circulation and oxygen cycling in the Mediterranean Sea: Sensitivity to future climate change
(American Geophysical Union, 2016-11-12)Climate change is expected to increase temperatures and decrease precipitation in the Mediterranean Sea (MS) basin, causing substantial changes in the thermohaline circulation (THC) of both the Western Mediterranean Sea ... -
Comparative study of transient hydraulic tomography with varying parameterizations and zonations: Laboratory sandbox investigation
(Elsevier, 2017-11-01)Transient hydraulic tomography (THT) is a robust method of aquifer characterization to estimate the spatial distributions (or tomograms) of both hydraulic conductivity (K) and specific storage (Ss). However, the ... -
A comprehensive study of geothermal heating and cooling systems
(Elsevier, 2019-01-01)Geothermal heat is an energy source that is local, reliable, resilient, environmentally-friendly, and sustainable. This natural energy is produced from the heat within the earth, and has different applications, such as ... -
Contrasting accessory mineral behavior in minimum-temperature melts: Empirical constraints from the Himalayan metamorphic core
(Elsevier, 2018-07-01)Medium-grained leucogranite in the Tama Kosi region of the Nepalese Himalayan Metamorphic Core yields a relatively narrow range of monazite 208Pb/232Th dates with a dominant population at ~21.0 Ma inferred to represent ... -
Control of mercury and methylmercury in contaminated sediments using biochars: A long-term microcosm study
(Elsevier, 2018-05-01)The effectiveness of activated carbon and four types of biochar, switchgrass (300 °C and 600 °C), poultry manure (600 °C), and oak (∼700 °C) with respect to mercury (Hg) and methylmercury (MeHg) control was assessed in ... -
Corundum formation by metasomatic reactions in Archean metapelite, SW Greenland: Exploration vectors for ruby deposits within high-grade greenstone belts
(Elsevier, 2018-05-01)Corundum (ruby-sapphire) is known to have formed in situ within Archean metamorphic rocks at several localities in the North Atlantic Craton of Greenland. Here we present two case studies for such occurrences: (1) Maniitsoq ... -
Data on removal kinetics of pharmaceutical compounds, artificial sweeteners, and perfluoroalkyl substances from water using a passive treatment system containing zero-valent iron and biochar
(Elsevier, 2019-12)The data presented in this paper relate to the research paper “Removal of pharmaceutical compounds, artificial sweeteners, and perfluoroalkyl substances from water using a passive treatment system containing zero-valent ... -
Diagenetic history and reservoir properties of the Cenomanian-Turonian carbonates in southwestern Iran and the Persian Gulf
(Elsevier, 2017-12-01)Shallow-marine carbonates of the mid-Cretaceous Sarvak Formation are important reservoir rocks in southern Iran and the Persian Gulf region. These carbonates were deposited on the margin of the Arabian Plate and rest on ... -
A diagnostic approach to constraining flow partitioning in hydrologic models using a multiobjective optimization framework
(American Geophysical Union, 2017-04-21)Hydrologic models are often tasked with replicating historical hydrographs but may do so without accurately reproducing the internal hydrological functioning of the watershed, including the flow partitioning, which is ... -
