Significant seabird mortality on the Oregon (OR) and Washington (WA) coast in 2009 has been attributed
to a massive bloom of the dinoflagellate Akashiwo sanguinea (K. Hirasaka) G. Hansen & Ø. Moestrup.
Initial, albeit limited, observations suggested this bloom began in WA and reached OR waters through
southward transport. Here,...

Variable ocean conditions can greatly impact
prey assemblages and predator foraging in marine ecosystems.
Our goal was to better understand how a change in
ocean conditions influenced dietary niche overlap among
a suite of midtrophic-level predators. We examined the
diets of three fishes and one seabird off central Oregon
during...

Fishery management production models tend to stress only the elements directly linked to fish (i.e. fish, fish food, and fish predators). Large coastal jellyfish are major consumers of plankton in heavily fished ecosystems; yet, they are frequently not included as model components. We explore the relationship between gulf menhaden (Brevoortia...

Accurate assessment of specific mortality factors is vital to prioritize recovery actions for threatened and
endangered species. For decades, tag recovery methods have been used to estimate fish mortality due to avian
predation. Predation probabilities derived from fish tag recoveries on piscivorous waterbird colonies typically
reflect minimum estimates of predation...

Variable ocean conditions can greatly impact lower trophic level prey assemblages in marine ecosystems, with effects propagating up to higher trophic levels. Our goal was to better understand how varying ocean conditions influence diets and niche overlap among a suite of low- to mid trophic level predators. We studied the...

As part of the California Current Ecosystem Survey, NOAA Fisheries sponsored pairs of
seabird observers who collected quantitative information on marine bird species,
abundance, and behavior during all daylight hours when the ship was under way.
Observers participated on Leg 1 and Leg 2 of the April 2008 Miller Freeman...
