Summer Lake, Oregon is one of the 20 terminal lakes identified by USGS partners as priority ecosystems for study by the Saline Lakes Ecosystems IWAA.

A soil moisture data logger buried in the ground is a specialized instrument designed to measure and record the moisture content of soil over time. Here's how it generally functions:

Lake Abert, Oregon is one of the 20 terminal lakes identified by USGS partners as priority ecosystems for study by the Saline Lakes Ecosystems IWAA.

This map shows the airborne geophysical survey area and planned flight paths across the Illinois River Basin in Illinois and northwest Indiana. Surveys will not occur directly above populated areas. Planned flight lines and survey progress can be found online.

Steamboat Geyser eruption signals recorded by nearby monitoring instruments. The vertical pink lines mark when the signal first appears. (A) Seismic station YNM records a signal which slowly tapers as the eruption decreases in intensity. Spikes seen before the eruption are mostly due to human activity.

Groundwater in aquifers between layers of poorly permeable rock, such as clay or shale, may be confined under pressure.

Steamboat Geyser erupts in the golden light of sunrise on July 18th, 2019. The water-dominated part of a Steamboat eruption usually lasts anywhere from 3 to 90 minutes. Afterwards, a steam-dominated phase continues for many hours.
