Fish dissection for histopathology analyses
Dr. Cheyenne Smith of the USGS Eastern Ecological Science Center coaches USGS Idaho Water Science Center hydrologic technician Niko Parrish in dissecting a mountain whitefish from northern Idaho's Kootenai River. The samples for histopathology analyses were collected as part of monitoring and assessment of water quality in the transboundary Kootenai River basin.

Observing osprey nest
USGS scientist observing an osprey nest. Use of a mirror pole allows the researcher to observe the nest from a boat without disturbing the nest. The image was taken during a USGS study of osprey (Pandion haliaetus) and their prey (menhaden (Brevoortia tyrannus), and other species of fish) in the middle and lower Chesapeake Bay and its tributaries.
