The Gulf of Alaska is one of the most productive marine ecosystems on Earth, supporting salmon fisheries that alone provide nearly $1 billion per year in economic benefits to Southeast Alaska. Glaciers are central to many of the area’s natural processes and economic activities, but the rates of glacier loss in Alaska are among the highest on Earth, with a 26-36 percent reduction in total volume expected by the end of the century. This project brought together scientists and managers at a workshop to synthesize the impacts of glacier change on the region’s coastal ecosystems and to determine related research and monitoring needs. Collected knowledge shows that melting glaciers are expected to have cascading effects...

As glaciers melt from climate change, their contents – namely, large quantities of freshwater, sediment, and nutrients – are slowly released into coastal ecosystems. This project addressed the impacts of melting glaciers on coastal ecosystems in the Copper River region of the Gulf of Alaska, which is home to several commercially important fisheries. Researchers examined how glacial melting is altering the amount and timing of freshwater that enters the Gulf of Alaska from the Copper River. They also investigated the source and amount of two nutrients, iron and nitrate, dissolved in the water. As a complementary piece of the study, researchers tested the relationship between nutrient levels, plankton populations,...

The primary objective of the research is to develop a rule-based decision support system to predict the relative vulnerability of nearshore species to climate change. The approach is designed to be applicable to fishes and invertebrates with limited data by predicting risk from readily avialable data, including species’ biogeographic distributions and natural history attributes. By evaluating multiple species and climate stressors, the approach allows an assessment of climate vulnerability across habitat types and the impact of specific climate alterations as well as their cumulative impact. A website with a rule-based application for rockfish and crabs is availalble at http://cbrat.org/.

Applications and Tools,
In 2012, US Geological Survey (USGS) and National Oceanic & Atmospheric Administration (NOAA) embarked on an ambitious project to digitize surficial seafloor data from existing National Ocean Service (NOS) smooth sheets in the Gulf of Alaska including numerous bays bordering the Gulf. USGS and NOAA are using the data for the nation-wide usSEABED project that seeks to compile and unify existing seafloor characterization point data into GIS-friendly data using the dbSEABED program (Jenkins, 1997; Reid and others, 2005; Buczkowski and others, 2006; Reid and others, 2006) and for the North Pacific Research Board’s Gulf of Alaska Integrated Ecosystems Research Program (NPRB, GOA-IERP, http://www.nprb.org/gulf-of-alaska-project)...
