The USGS Cascades Volcano Observatory utilizes a multi-rotor unmanned aircraft system (UAS) outfitted with a miniature USGS-developed MultiGAS sensor to measure quiescent gas emissions above the 2004–2008 lava dome within the crater of Mount St. Helens. These new technologies allowed the team to characterize degassing at Mount St.

Underground coal fires can burn for years, and are a serious health and environmental hazard. There are four underground coal fires in northern New Mexico: two in close proximity to Gallup, one north of Farmington, and one south of Raton. The New Mexico Abandoned Mine Land Program (NMAMLP) has contracted several coal fire assessments to assist with the development of mitigation/extinguishment plans for these fires.

Primary production estimates in different lake habitats are being used to parameterize food web models and illustrate how changes in nutrient loads may influence water clarity. Accurate estimates of primary production are crucial for this task, and USGS scientists and key partners are leading the way for Lake Ontario.
