Mineral precipitates in mine tunnels, such as the copper-rich minerals in this mine in Oregon, may provide information on the paths of groundwater that discharge into the tunnels, informing strategies for metal recovery and potential remediation. 

Laboratory research: Bioelectrochemical system for critical mineral recovery from mining by-products.

Tailings piles at abandoned mine sites can be reprocessed to recover critical minerals and rare earth elements.

Montana is known for its fishing opportunities, especially its cold-water trout fishing. Here, someone is fishing in Big Hole River, Montana. 

The Ruby River is a tributary of the Beaverhead River and anglers enjoy trout fishing here.  

Autonomous environmental DNA (eDNA) sampler in protective housing on the shore of Jackson Lake, Grand Teton National Park. The USGS READI-Net project and eDNA samplers like this one can assist the park in detecting aquatic invasive species, like quagga mussels.

Orange streams are increasingly common in the Brooks Range of northern Alaska. The orange stream color reflects oxidized iron, but also often indicates elevated heavy metal concentrations. Our ongoing study aims to document these occurrences and the timing of their onset.

Photographs from a mountainous star coral (Montastraea cavernosa) losing tissue to disease in Florida, USA.  (A) Colony in situ showing bare white, recently denuded skeleton with no turf algae growth (arrowheads) with dark discoloration along the active tissue loss margins (arrows).

Photomicrographs from a mountainous star coral (Montastraea cavernosa) in Florida, USA. (A) A large cluster of filamentous bacteria are within the gastrovascular space and gastrodermis (asterisk) and extending through mesoglea (arrow) with necrosis and loss of the surface gastrodermis (arrowheads). H&E stain.  Scale bar 200 μm.
