Scientists Sarah Laske (USGS ASC), Daniel Fraser (University of Texas and Beaufort Lagoons LTER), and Ashley Stanek (USGS ASC), empty the daily catch of nearshore fishes from a fyke net to a floating net pen in Jago Lagoon in the Arctic National Wildlife Refuge. Note the slumping tundra right along that coastline.

Dolly Varden (Salvelinus malma) char captured in brackish water along the Beaufort Sea coastline. Dolly Varden are an important subsistence fish across their range.

Members of the science party and the crew of R/V Rachel Carson work to recover an instrumented tripod.

This photo shows an outcrop of pyroclastic flow deposits near Willow Creek on the Pumice Plain at Mount St. Helens. The dramatic lines crossing the outcrop indicate contacts between different layers of pyroclastic flow deposits. Two participants of the 2019 GeoGirls program are shown studying the outcrop, using it to understand the eruptive history of the volcano.

The instrumented tripod is successfully brought onboard for data download.
