On Tuesday, December 10 HVO staff visited Keller Well, a deep borehole at the summit of Kīlauea, to take quarterly measurements and samples. This photo shows an extra long measuring tape, which has a sensor attached to the end, being lowered into the well to measure the distance to the top of the water table.

This is a view of a USGS surface water stream gage that contains equipment to monitor discharge at the Williamson River below the Sprague Ruver in Chiloquin, Oregon. The gage house contains a historic stilling well and a device that records the level of water. It also has a water temerature sensor and a turbidimeter.

EROS scientists track water availability and crop health around the world to help governments and non-profits manage resources and stave off food shortages. But EROS also teaches international scientists to track those resources themselves. In this episode, we hear about a recent training session at EROS for Iraq’s Ministry of Water Resources.
