Groundwater potential zone map** by combining remote sensing, modified DRASTIC method and field data for Bidou I, South Cameroon
Assessment of groundwater resources in southern Cameroon by remote sensing techniques is almost non-existent, and therefore limit knowledge on the groundwater potential in Cameroon. This work aims to delineate...

Recharge and baseflow constrained by surface-water and groundwater chemistry: case study of the Chari River, Chad basin
The Chari-Logone watershed is the only hydrologically active part of the Lake Chad Basin (Central Africa). The Chari-Logone River and Lake Chad exchange water with the surrounding unconfined aquifers of sedime...

Revisiting recharge and sustainability of the North-Western Sahara aquifers
In recent years, geochemical and geophysical studies have challenged the commonly held view that the use of fossil Sahara aquifers is completely unsustainable because they have not been recharged since the las...

Open AccessPronounced interannual variability in tropical South Pacific temperatures during Heinrich Stadial 1
The early last glacial termination was characterized by intense North Atlantic cooling and weak overturning circulation. This interval between ~18,000 and 14,600 years ago, known as Heinrich Stadial 1, was acc...

Ice-sheet collapse and sea-level rise at the Bølling warming 14,600 years ago
Past sea-level records provide invaluable information about the response of ice sheets to climate forcing. Some such records suggest that the last deglaciation was punctuated by a dramatic period of sea-level ...

Natural and anthropogenic budgets of a small watershed in the massif central (France): Chemical and strontium isotopic characterization of water and sediments
A small watershed (160 km2) located in the Massif Central (France) has been chemically, isotopically and hydrologically studied through its dissolved load, bed sediments and soils. This watershed is underlain by ...
