USGS water-quality instruments to measure nutrient levels

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.

Spring sampling in Wyoming

Spring sampling location along Little Sandy River in southern Wyoming. 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.S. Geological Survey study

Forty years ago on July 31, as Coloradoans and tourists celebrated the state’s centennial, between 12 and 14 inches of rain fell over a four-hour period in the mountains below the resort town of Estes Park, killing 143 people. The 1976 Big Thompson flood stands as the worst natural disaster in Colorado’s recorded history.

Alaska is a major producer of base and precious metals and has a high potential for additional undiscovered mineral resources. However, discovery is hindered by Alaska’s vast size, remoteness and rugged terrain. New methods are needed to overcome these obstacles in order to evaluate Alaska’s geology and mineral resource potential.

The U.S. Geological Survey has produced a new compilation of landscape-scale sediment and soil geochemical data for Alaska. This was last completed nearly 40 years ago in 1978, but the new effort uses modern modeling and analysis techniques to map 68 elements across a newly developed and updated geochemical atlas of Alaska.
