Offshore Freshened Groundwater and Related Infrastructure Database

OFG Feasibility Map: Mapping features of OFG findings, Desalination plants, Water stress, Gas & Oil platforms and OFG predictions. Calculating then distances between OFG sides and infrastructure / land, sloping profiles, and seafloor properties to conclude which sides are feasible to use OFG in a cost efficient way (building piping / platforms / desalinations plants) Dataset name Description Reference OFF-SOURCE OFG Database Database of OFG related datasets including boreholes and field surveys (Giustiniani et al. 2025) Offshore Fresh GW Estimates of offshore freshened groundwater volumes organized by COSCATT regions (Zamrsky et al. 2022) Coastlines (present-day) A 30-m spatial resolution global shoreline vector (Sayre et al. 2019) Paleo-coastlines Global extent of ice sheets at the last glacial maximum (LGM) approximately 18000 years before present (Ehlers and Gibbard 2004) Paleo-rivers The major inland waters (rivers and lakes) of Europe during the LGM (Jan Verheul et al. 2015) Global Groundwater Withdrawal (GGW) Global estimates of groundwater withdrawal trends and uncertainties (Nazari et al. 2025) Oil and Gas Infrastructure Mapping Global, spatially explicit, and granular database of oil and gas infrastructure (O'Brien et al. 2024) Aqueduct 3.0 Regional water stress (Hofste et al. 2019) Desalination Plants Location of water desalination systems across Europe (EMODnet 2024) WaterGap Global hydrological model that quantifies human use of groundwater and surface water (Müller Schmied et al. 2021) ViDEPI Publicly accessible database managed by the Italian Ministry for the Economic Development containing hydrocarbon exploration well data (ViDEPI 2025)
