Status: Active Harmful Algal Bloom Toxins in Alaska Seabirds
Warmer ocean temperatures are linked to the development of harmful algal blooms (HABs), which pose a growing threat to marine birds and other wildlife. During late 2015 and early 2016, a massive die-off of Common Murres was observed in the Gulf of Alaska coincident with a strong marine heat wave. Since then, the USGS has worked with a variety of stakeholders to rapidly develop testing methods...

Status: Active Detecting Long-term Changes in Forage Fish Populations in Prince William Sound, Alaska
Forage fish are an important node in marine food webs because they link primary and secondary producers with higher trophic levels.

Status: Active Cook Inlet Seabird and Forage Fish Study
A massive die-off of Common Murres was documented in the Gulf of Alaska (GOA) during the fall and winter of 2015-2016 in association with a record-breaking marine heat wave in the GOA.

Status: Active Terrestrial Influence on Glacial-Marine Food Webs
Where glaciers meet the sea in the Gulf of Alaska (GOA), they create unique and productive marine habitats. Ringed by the continent’s tallest coastal mountains, 20% of the GOA coastal watershed is covered by glacial ice and the annual freshwater discharge into the GOA from glacial melt is comparable to that of the Mississippi river.

Status: Active Seabirds and Forage Fish Ecology
Alaska's coastal and offshore waters provide foraging habitat for an estimated 100 million birds comprising more than 90 different species; from loons and seaducks that nest inland, to petrels and puffins that breed on islands off shore. All these birds depend on the sea to provide a wide variety of food types— from clams, crabs and urchins nearshore— to krill, forage fish, and squid offshore...

Status: Active Condition of Forage Fish in Prince William Sound During the Marine Heatwave
Changes in the body condition of a key forage fish species, Pacific sand lance (Ammodytes personatus), are examined to understand how energy transfer to predators may have been disrupted during the recent marine heatwave in the North Pacific (late 2013 to mid 2016).

Extreme reduction in nutritional value of a key forage fish during the Pacific marine heatwave of 2014–2016
Pacific sand lance Ammodytes personatus are a key forage fish in the North Pacific for many species of salmon, groundfish, seabirds, and marine mammals and have historically been important to predators in relatively warm years. However, extreme declines in the nutritional value of sand lance in Prince William Sound, Alaska, USA, during...

Avian predator buffers against variability in marine habitats with flexible foraging behavior
How well seabirds compensate for variability in prey abundance and composition near their breeding colonies influences their distribution and reproductive success. We used tufted puffins (Fratercula cirrhata) as forage fish samplers to study marine food webs from the western Aleutian Islands (53°N, 173°E) to Kodiak Island (57°N, 153°W), Alaska,...
