The maps below show groundwater isoscapes (\(\delta^2H\) and \(\delta^{18}O\)) for the United States. These isoscapes were developed as part of the work in Stahl et al. (2020). For additional details on the development of these isoscapes and for static versions of these maps see Stahl et al. (2020). Raster files with the isoscape data are available here.

Note: By moving your cursor over the map you can obtain the isotopic value (see map top right corner) latitude and longitude (see map top left corner) for a particular location.


Groundwater \(\delta^{2}H\) isoscape


Groundwater \(\delta^{18}O\) isoscape
