This is an image of a stormwater drain in Seattle. Dangerous tire particles, such as 6PPD-quinone, can land up in water bodies through drains such as the one depicted above and can cause deaths in a variety of fish, including salmon.

Volcanoes tend to have seismicity that waxes and wanes over time. That’s considered normal and not necessarily a cause for concern. Let’s check on Mount Adams to see what USGS scientists are doing to learn more about its recent earthquake activity and what it could mean for this Cascade Range volcano.

This is an image of Kenneth Tiffan out in the field. Ken works to conduct applied research to provide information that would increase our understanding of Snake River fall Chinook salmon, listed as “threatened” under the ESA in 1992. His career has focused on this unique stock and facilitating recovery efforts.

USGS 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.

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.

Photos shared by Dave Beauchamp from the first week of quantitative light measurements for the Artificial Light At Night (ALAN) project:
This week was a big data collection push, with 2 boats out nightly Tuesday through Thursday, plus day activities and prep.
