ABSTRACT:

- Global Groundwater Levels -
Annual groundwater level data described in the following publication: Jasechko, S. Seybold, H.S., Perrone, D., Fan, Y., Shamsudduha, M., Taylor, R.G., Fallatah, O., Kirchner, J.W. Rapid groundwater decline and some cases of recovery in aquifers globally. Nature, doi.org/10.1038/s41586-023-06879-8 (2024). Annual groundwater level data are available in cases where we have received permission from a database manager to post annual groundwater level data. These two .csv files contain annual groundwater level data for Afghanistan, Austria, Belgium, Brazil, Bulgaria, Canada (Alberta, British Columbia, Manitoba, Northwest Territories, Ontario, Prince Edward Island, Saskatchewan, Yukon), China, Croatia, Czech Republic, Denmark, France, Germany, Guam, Ireland, Israel, Italy, Latvia, Lithuania, New Zealand, Norway, Paraguay, Poland, Slovenia, Sweden, Switzerland, and the United States (Groundwater Ambient Monitoring and Assessment Program, US Geological Survey's (USGS) National Water Information System, and the Texas Water Development Board).

File 1 of 2 entitled "AnnualDepthToGroundwater.csv"
"StnID" - unique number for the monitoring well
"Lat" - latitude of the monitoring well (in some cases this may be an approximation)
"Lon" - latitude of the monitoring well (in some cases this may be an approximation)
"IntegerYear" - calendar year
"DepthToWater_m" - annual median depth to groundwater (units of metres below reference point and/or groundwater surface)

File 2 of 2 entitled "AnnualGroundwaterElevation.csv"
"StnID" - unique number for the monitoring well
"Lat" - latitude of the monitoring well (in some cases this may be an approximation)
"Lon" - latitude of the monitoring well (in some cases this may be an approximation)
"IntegerYear" - calendar year
"GroundwaterElevation_masl" - annual median groundwater elevation (units of metres above sea level)

ABSTRACT:

Here we present well water measurements that pre-date 1910. We compiled thousands (n=11, 369) of water level measurements reported in tables within US Geological Survey reports published in the early 1900s.

Our search for data sources took place from May-June 2021; our data compilation and transcription took place from June-October 2021; our data cleaning occurred in November 2021. Please see our metadata for detailed information on the digitization process.

ABSTRACT:

Here we present a geospatial dataset representing local- and regional-scale aquifer system boundaries, defined on the basis of an extensive literature review and published in GebreEgziabher et al. (2022). Nature Communications, 13, 2129, https://www.nature.com/articles/s41467-022-29678-7

The database contains 440 polygons, each representing one study area analyzed in GebreEgziabher et al. (2022). The attribute table associated with the shapefile has two fields (column headings): (1) aquifer system title (Ocala Uplift sub-area of the broader Floridan Aquifer System), and (2) broader aquifer system title (e.g., the Floridan Aquifer System).
