SF1. Subterranean freshwaters biome

Published

June 7, 2024

This page provides information about the valid indicative distribution map for the ecosystem functional group SF1.2 Groundwater ecosystems. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: SF1.2.web.orig v1.0.

Indicative global maps of Groundwater aquifers were based on Bundesanstalt für Geowissenschaften und Rohstoffe & UNESCO (2012) with colour ramp showing type of aquifer by recharge rate, only in major groundwater basins (type 11 (minor occurrences) to type 15 (major occurrences)).

Datasets

BGR-Groundwater-Basins (Bundesanstalt für Geowissenschaften und Rohstoffe BGR):

Source of topography and geomorphology. Resolution: >1km2, static. Accuracy evaluation: derived from sources.
