Welcome to G@GPS

The G@GPS (Groundwater@Global Palaeoclimate Signals) initiative is an inclusive group of scientists coordinating palaeogroundwater research. The aim is to interpret links between palaeoclimate archives and paleogroundwater observations at continental and intercontinental scales. Understanding the responses of groundwater to past, present and future climates is vital to manage limited groundwater resources. The palaeoclimatic signals potentially obtained from groundwater are of low temporal resolution; however, they can offer an integrated signal from vast geographical areas. This information is key in understanding long term evolution of major aquifer systems.

Flag Basin Aquifers

G@GPS will target large aquifers or regions where pre-existing research is available and a small number of additional analysis could add substantial value. Initially, emblematic aquifers “flag basins” will be targeted in most continents, but G@GPS will increase the number of basins targeted as new collaborations and research projects are developed. Flag basin include the following.

     Africa: North West Sahara Aquifer System (NWSAS).

     America: (North America) High Plains Aquifer (HPA). (South America) Guaraní Aquifer System (GAS).

     Asia: North China Plains Aquifer (NCPA).

     EuropeBaltic Artesian Basin (BAB).

     Oceania: Great Artesian Basin (GAB) and the Sydney Basin aquifers (SBa).

These basins contain vast groundwater resources and it is estimated that tens (if not 100s) of millions of people rely on them either directly or indirectly. Uncontrolled groundwater extraction in some of those aquifers has caused irreversible depletion. Understanding the recharge history of these aquifers will provide solid scientific data that are essential for modellers to predict future impacts, and hence for water managers who rely on such predictions.
