This is an informational graphic detailing how sky glow works.

Photo showing a typical setup for nighttime light mapping by boat. The Mk9, BioMAST, and SQM each collect light data in different ways, so researchers can deploy them simultaneously and compare data between the instruments.

The 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.

Not all lighting is the same, especially in water. Light can have different effects on fish and wildlife based on angle and color.

Photo showing nighttime data collection on Lake Union, with Seattle in the background. Researchers collected daytime and nighttime data on Lake Union and the Lake Washington Ship Canal during peak juvenile salmon outmigration (in the spring) to investigate where the juvenile salmon congregate as they make their way out to the Puget Sound.

This photo below also shows all the tags that Western Fisheries Research Center scientists use to implant in fish, in reference to a quarter. From top to bottom: quarter, SS300P (depth sensing) acoustic tag, SS400 acoustic tag, ELAT acoustic tag, and a 12mm PIT tag on the bottom.

This is a dredge material deposition site named the Woodland Islands. Western Fisheries Research Center scientists study this area as habitat for fish like salmon.
