Artificial Light at Night Pool Experiment Infographic
Artificial Light at Night Pool Experiment InfographicThe goal of this experiment is to determine the relationship between light level and predator fish reaction distance. This is part of the larger body of fish ecology work on how artificial light at night affects salmon survival in Washington waters.

Juvenile Sucker in Upper Klamath Lake, OR
This is a video of a juvenile sucker in Upper Klamath Lake, OR. Through decades of research, scientists at the USGS Western Fisheries Research Center have determined that over the last 30 years something has prevented young suckers from reaching adulthood. Scientists work tirelessly to find the cause of this break in recruitment into adulthood.

Eyes on Earth Episode 84 - Hurricane Disturbance Mapping
Eyes on Earth Episode 84 - Hurricane Disturbance MappingWhen disaster strikes, near-real-time images of its effects can be invaluable. In this episode of Eyes on Earth, we learn about how a newly developed system using the Harmonized Landsat Sentinel-2 dataset and artificial intelligence was put to the test when Hurricane Ian tore through Florida in late September 2022.
