USGS Transboundary River Monitoring in Southeast Alaska
The USGS Alaska Science Center operates super gages on the Alsek, Taku, Stikine, Unuk and Salmon Rivers. Discrete water quality, sediment, and biological sampling are also collected at each gage location. Discrete water quality samples are also collected annually at the Canada-Alaska border crossings of the Taku, Stikine, and Unuk Rivers. Water quality data collection began in 2018 on the Unuk...
Community Outreach and Engagement
It is critically important that Indigenous peoples, rural communities, and Alaska co-management councils are kept informed of USGS research activities and findings. Involvement of and collaboration with these stakeholders provides valuable perspectives. This page offers information on how USGS communicates and seeks out important perspectives from stakeholders.
Satellite-based Remote Sensing of River Discharge
The U.S. Geological Survey and NASA are collaborating on a study to develop methods to estimate river flows from satellite observations.
Compilation of Historical Water Temperature Data for Large Rivers in Alaska using the Landsat Satellite Archive
Water temperature is one of the key elements of freshwater ecosystems and is a critical element within natural resources monitoring programs. In Arctic and sub-Arctic rivers, water temperature especially relates to the physical and biological features of a river, as it affects how rivers interact with portions of the landscape and the life cycles and composition of stream life and ecosystems. This
Suspended-Sediment and Solids Sampling
Suspended-sediment samples are collected on each visit at both gage and border site locations.
Natural Resources Preservation Program
This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and National Park Service staff address priority research needs identified by the National Park Service. On this page, we highlight research taking place in Alaska as part of this program.
Collaborative Science for Priority Information Needs
One of the primary missions of the USGS is to address the science needs of Department of Interior bureaus, particularly those that manage natural resources and lands. This mission is fulfilled through the research and other activities of USGS scientists but also specifically through three USGS nationally-funded programs listed below.
Outer Continental Shelf Program
This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and Bureau of Ocean Energy Management staff address priority research needs identified by the Bureau of Ocean Energy Management. On this page, we highlight research taking place in Alaska as part of this program.
Science Support Program and Quick Response Program
This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and U.S. Fish and Wildlife Service staff address priority research needs identified by the U.S. Fish and Wildlife Service. On this page, we highlight research taking place in Alaska as part of this program.
Improving Forecasts of Glacier Outburst Flood Events
Suicide Basin is a glacier-fed lake that branches off Mendenhall Glacier in Juneau, Alaska. Since 2011, Suicide Basin has been collecting melt- and rainwater each summer, creating a temporary glacier-dammed lake. Water that accumulates typically gets released through channels that run beneath the glacier. These channels are normally blocked by ice, but if the water pressure gets too high the chann
Unuk River
The Unuk River is the second smallest watershed in the transboundary study of Southeast Alaska, but has three large mining projects in development (Kerr-Sulplherets-Mitchell (KSM), Brucejack, and Eskay Creek).
Stikine River
The Stikine River near Wrangell and Petersburg is the largest watershed in the transboundary study of Southeast Alaska.
