2. However, the location and extent of groundwater-dependent ecosystems (GDEs) are unknown in many geographies, and protection measures are lacking1,3. Here, we map GDEs at high-resolution (roughly 30 m) and find them present on more...

Aquifers in peripheral mountain massifs stem from the fracturing and weathering of igneous and metamorphic rocks. Peripheral aquifers present similar recharge and discharge conditions as the Iberian range aquifers. Though more limited in size and storage capacity, peripheral aquifers are often important fo...
These critical underground tests often occurred within aquifers or below water tables, gaining the site further scrutiny. Many of the site’s opponents noted that the environmental damage from the atmospheric tests had simply taken a different form. Radioactive materials have also been buried undergrou...
One of the more beautiful, unusual and useful map projections ever devised was created by cartographerBernard Cahill. The butterfly projection was first published in theScottish Geographical Magazinein 1909. Cahill (1866-1944) later applied for a US patent to protect his creation. ...
The group has developed a pilot technology that can monitor and track the use of groundwater in real time along the delta of the San Joaquin River, one of the largest and most at-risk aquifers in North America.68 • Earth Observation and Remote Sensing analytics: These technologies can ...
