Hydrologic technician Garret Welsh carries a large ice auger while walking across the frozen St. Croix river near streamgage 05341550 in Stillwater, Minnesota.

Hydrologic technician Garret Welsh conducts an Ice Rod measurement through an augered hole in the frozen St. Croix river near streamgage 05341550 in Stillwater, Minnesota. An Ice Rod is a heavy-duty, 1-inch (2.5 centimeter) diameter, lightweight aluminum rod used for suspending ice meters in fast velocities.

The U.S. Nuclear Regulatory Commission (NRC) regulates uranium mill tailings under the Uranium Mill Tailings Control Act of 1978. This drawing is a straight-forward cross sectional schematic of the different types of mill tailing covers.

This image was drawn for a fact sheet on Uranium mining in the Grand Canyon region, but was ultimately unused.  It still has utility to serve as inspiration to those who want to form ideas on how their science can be represented.  The image is quite literally, a view into the Grand Canyon.  But on a deeper level also is a conglomerate of both the geol

The left axis is a visualization of an ensemble of solutions (crosses and dashed lines) iteratively moving down gradient on an objective function surface (color flood) in 2-D parameters space, with the associated prior (gray) and posterior (blue) parameter marginal distributions shown on the two right stacked axes.

Hydrologic Technician Matt Bach measuring streamflow day after a rain event at USGS streamgage 04085078, DUTCHMAN CREEK AT HANSEN RD AT ASHWAUBENON, WI, using an Acoustic Doppler Current Profiler (ADCP). The ADCP measures water currents by transmitting "pings" of sound at a constant frequency into the water.
