USGS scientists use multiple high-frequency water quality instruments contained in a cage to measure nutrients and algal changes in surface water. Scientists are conducting an experimental study on two Utah water bodies to gain a better understanding of nutrient levels, which could help determine how to best manage algal bloom outbreaks.

Monterey Bay Aquarium Research Institute researchers launch the long-range autonomous underwater vehicle Tethys from the research vessel Paragon in Monterey Bay. This AUV travels through the water without direct control from shore, collecting information about the physical, chemical, and biological characteristics of the surrounding seawater.

The information collected by advanced technologies, like this uncrewed underwater vehicle, can be used by managers to sustain and support the Great Lakes’ valuable natural resources.

Scientists sample a rough-skinned newt for the fungal pathogen Batrachochytrium salamandrivorans, or Bsal, at a pond near Portland, Oregon. Bsal is decimating wild salamander populations in Europe and could emerge in the U.S. thro

Can you do the Charleston? This animated GIF takes frames from a USGS video on the gila monster and reverses them to make this Southwestern lizard shake his tail...or perhaps dancing the Charleston. 

USGS scientist collects noble gas sample from spring site near Roaring Judy, Colorado. Groundwater discharge that flows into the Upper Colorado River Basin varies in response to drought, which is likely due to aquifer systems that contain relatively young groundwater, according to a new U
