USGS scientist Victoria Scholl collecting ground data during a UAS mission along the North Santiam River

The USGS Oregon Water Science Center teamed up with the NUSO in August 2021 to explore bathymetric and remote sensing techniques to detect periphyton, a complex mixture of algae, cyanobacteria, and microbes in freshwater ecosystems.

In June 2021, eight months after the East Troublesome Fire burned over 193,000 acres in Colorado, NUSO performed UAS data collection over several of the burn scars representing different fire intensity levels and fuel types.

During the summer of 2019 NUSO researchers evaluated the viability of using UAS platforms and data collection sensors to characterize and evaluate an urban forest. 

The stratigraphic architecture of fluvial deposits reveals changes in river behavior associated with active tectonism and climatic change.
