Artificial light at night (ALAN) can be a threat to aquatic ecosystems. Light in the sky penetrates through the water and brightens the water column. Even small increases in light at night can dramatically improve some predators’ ability to hunt and kill their prey.

Light Sensor Attached to Boat for Artificial Light At Night StudyUSGS Western Fisheries Research Center scientists are investigating the relationship between ALAN, predators’ hunting ability, and juvenile salmon survival in Lake Washington. This includes using a new instrument that overcomes significant issues experienced when attempting to measure light at night underwater.
