Dataset: Depth-stratified krill net samples taken in Puget Sound, WA aboard R/V Clifford A. Barnes during cruises CB1073 and CB1078 in 2017.

We sampled the density of all euphausiid life stages during dusk (within 1 hour of sunset) with a 60-cm diameter, 200-μm mesh ring net lifted vertically from 10 m off the bottom to the surface. We also characterized the nighttime density and vertical distribution of adult Euphausia pacifica using a 0.25 m2 Hydrobios MultiNet (five-net capacity) towed obliquely to collect depth-stratified samples. Flowmeters were used to monitor the volume of water filtered for all collections and samples were preserved in a 5% buffered formalin and seawater solution.
