Stable isotope compositions of present day precipitation in the 70°E–160°W longitude range reveal a strong correlation with moisture source and transport patterns are not correlated amount precipitation, contrary to existing interpretations. Spatially temporally variable sources cyclonic circulation result more depleted values (δ 18 O ∼ −5 −7‰) 100°E–170°E range. Oceanic minimal continental loss or input results comparatively enriched δ (∼−2 −4‰) 70°E–100°E east 170°E. Isotope dated...
Open access to harmonised digital data describing Earth's surface and subsurface holds immense value for society. This paper highlights the significance of open geoscience ranging from shallow topsoil or seabed depths 5 km. Such play a pivotal role in facilitating endeavours such as renewable geoenergy solutions, resilient urban planning, supply critical raw materials, assessment protection water resources, mitigation floods droughts, identification suitable locations carbon capture storage,...
Temperature is a critical factor at the interface between water and energy stakeholders. It plays vital role in enabling them to sustain develop their activities without competing for resources, particularly during periods of crisis. Both surface bodies subsurface compartments (
The Water Framework Directive (WFD) aims to protect and improve water quality across Europe through an integrative multi-level governance approach. goal is ensure that in meets good ecological status by 2027. Whilst the WFD has been hailed as a cornerstone for innovation management, most EU member states (MS) still struggle achieve of their waters. realignment structure under discretionary, generated diversity implementation approaches final arrangements MS. This may contribute low...
Abstract Isotope hydrological studies carried out since 1987 in Haiti have proven to be effective improving conceptual models of the principal aquifers this Caribbean island nation. However, many these been limited and are mostly unpublished. It is, therefore, important share available datasets with scientists water managers support further guide decision-making. Eleven were compiled a unique database for continued advancement application. This dataset now contains 248 δ 18 O 2 H results...
The International Atomic Energy Agency/World Meteorological Organization Global Network for Isotopes in Precipitation (IAEA/WMO GNIP) data base includes more than 100,000 δ 18 O,δ 2 H, and 3 H measurements performed on monthly precipitation samples collected at 550 stations worldwide. Since 1961, the has served as a baseline reference distribution of water isotopes modern precipitation. It is widely used fields isotope hydrology, climatology oceanography paleoclimatology.
The Water Framework Directive (WFD) requires EU member states to assess the chemical status of groundwater bodies, a defined according threshold values for harmful elements and based on/the natural background level (NBL). NBL is as expected value concentration naturally present in environment. aim this study propose methodology that will be broadly applicable wide range conditions at regional national scale. Using statistical approach, seeks determine NBLs SO4, As, Cd, Cr, Cu, Ni, Zn, F on...
Rainwater, groundwater and soil-water samples were analysed to assess geochemistry the origin of salinity in Ochi-Narkwa basin Central Region Ghana. The measured for major ions stable isotopes (δ18O, δ2H δ13C). Cl− content rainwater decreased with distance from coast. hydrochemical facies Na-Cl shallow groundwaters Ca-Mg-HCO3, Ca-Mg-Cl-SO4 deep groundwaters. Groundwater salinization is caused largely by halite dissolution a minor extent silicate weathering seawater intrusion. Stable isotope...
Access to fresh water is one of the major issues northern and sub-Saharan Africa. The majority used for drinking irrigation obtained from large ground basins where there minor contemporary recharge aquifers cross national borders. These include Nubian Aquifer System shared by Chad, Egypt, Libya, Sudan; Iullemeden System, extending over Niger, Nigeria, Mali, Benin, Algeria; Northwest Sahara Algeria, Tunisia. resources are subject increased exploitation may be severely stressed if not managed...
The controlled landfill technology is now adopting passive attenuation techniques as an increasing number of sites reach the post-closure phase. During phase, operators need to convince environmental authorities that landfills no longer pose a threat health or environment. demonstration acceptable risk should rely in particular on data collected during monitoring addition modelling possible future evolutions concentrations. One difficulty typically encountered France related fact groundwater...
The distribution of the high concentrations arsenic (As) and fluoride (F-) in groundwater on a Pan-European scale could be explained by geological European context (lithology structural faults). To test this hypothesis, seventeen countries eighteen survey organizations (GSOs) have participated dataset. methodology has used HydroGeoToxicity (HGT) Baseline Concentration (BLC) index. results prove that most waters considered study are good conditions for drinking water consumption, terms As...
Understanding water exchange between streams and groundwater, or surface water-groundwater interactions, is of primary importance for solving conflicts related to use restoring ecosystems.The main goal this study was demonstrate that combination classic geochemical tools isotopic (δ 2 H δ 18 O water, 34 S SO4 sulfates, 87 Sr/ 86 Sr) can lead a better understanding -groundwater interactions alluvial aquifer in the Alpes mountains (Isère River aquifer) used drinking supply.We report here...
Groundwater of the Carboniferous limestone transboundary aquifer northern France and Belgium has sulfate concentrations ranging from 20 to more than 1000 mg.l−1, in some parts a clear increase over several years been observed. The hydrogeochemical study that was carried out within whole highlights complex geochemical pattern due existence various processes such as water-rock interaction, ion exchange, different origins sulfates, oxidation sulfur minerals, dissolution secondary primary...
