eDNA sample collection
USGS volunteer Liliana uses a syringe to draw an eDNA sample from a rock pool along the Puka Stream. The eDNA sampled by USGS field crews informs research on invasive mosquito population dynamics.

USGS Continuous Nutrient Monitoring in the Mississippi River Basin
USGS “supergages” are very complex. Continuous concentrations of nutrients and streamflow are measured at supergages and the information is available to the public in real-time.

Detecting Invasive Species in the Field: Portable eDNA Screening Tool
The USGS field tested the use of a portable hand-held kit for the detection of the environmental DNA (eDNA) of Asian carps (bighead carp and silver carp) in water samples as part of on-going invasive species detection research. The goals of the USGS-led research are to develop a method and kit that can be used on-site to detect Asian carp eDNA within one hour.
