This dataset includes spatial location information from 167 temperature data loggers that were installed throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 30 and August 14, 2015. One hundred twelve data loggers were installed in stream channels (some of which were dry), 50 data loggers were installed outside the stream channel to measure air temperature, and 5 data loggers were installed on ridgetops to measure air temperature across the watershed.

This dataset includes stream temperatures from a network of 112 data loggers that was installed in stream channels throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 31 and August 15, 2015. Ninety-seven data loggers were recovered and downloaded in late July 2016.

The U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers—Louisville District conducted a pilot study on the use of an autonomous underwater vehicle (AUV) for a survey of water conditions during August 2016 in a portion of Nolin River Lake, Kentucky. The AUV was equipped with sensors for the continuous collection of water-quality measurements for dissolved oxygen, pH, specific conductance, temperature, turbidity, total chlorophyll, and blue-green algae concentrations. The AUV continuously collected measurements of these water-quality parameters while traveling at varied depths in a set spatial pattern within a portion of the lake. In addition to the AUV survey, discrete nutrient- and...

This 1:50,000-scale geologic map represents a compilation of the most recent geologic studies of the upper Arkansas River valley, between Leadville and Salida, Colorado. The valley is structurally controlled by an extensional fault system that forms part of the prominent northern Rio Grande rift, an intra-continental region of crustal extension. This work also incorporates new detailed geologic mapping of poorly understood areas within the map area and reinterprets previously studied areas, aided by lidar data that covers 59 percent of the map area. The mapped region extends into the Proterozoic metamorphic and intrusive rocks in the Sawatch Range west of the valley and the Mosquito Range to the east. Paleozoic...

This dataset includes air temperatures from 50 data loggers that were installed in tandem with stream temperature data loggers, as well as five ridgetop data loggers, throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 31 and August 15, 2015. Fifty-one data loggers were recovered and downloaded in late July 2016.
