This project evaluates the connections between climate change impacts and health in Bristol Bay communities. Climate change impacts were assessed through the lens of public health, with an eye towards the potential effects on disease, injury, food and water security, and mental health. Three focal communities were included in this assessment: Nondalton, a lake community, Levelock, a river community, and Pilot Point, a coastal community. The resulting assessment reports will be used to assist focal communities, as well as neighboring communities, in addressing climate-change related issues.

Contemporary observations suggest that water may disappear entirely from portions of some North Slope stream-beds during periods of drought or low flow. Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.

Arctic grayling (Thymallus arcticus) have a life-history strategy specifically adapted to the extreme climate of the North. These fish migrate to spawning grounds just after breakup in the spring, then migrate to feeding sites in early summer, and finally in the fall migrate back to their overwintering sites. The Kuparuk River is a perennial stream originating in the northern foothills of the Brooks Range on the North Slope of Alaska. Sections of the Kuparuk are periodically intermittent in that, during low flows in the system, these channel reaches appear dry. The flow varies between surface and subsurface in this permafrost-dominated environment, with subsurface flow being limited to the unfrozen thaw bulb around...

The Red River Stakeholder Engagement project’s primary objective was to uncover areas of concern for stakeholders who live, work, and play along the Red River Basin. It examined the complexity of the cultural-geographic landscape across the Red River Basin. By focusing on both the geographic and the cultural, we gain a better understanding of how individuals, communities, and organizations interact with the basin and with one another, how they arecurrently experiencing changes, and what they perceive a changing climate means for them.This cultural-geographic approach recognizes that stakeholders’ concerns, priorities, and actions likely vary across space-and also vary in their cultural significance. For example,...

Watersheds draining the Arctic Coastal Plain (ACP) of Alaska are dominated by permafrostand snowmelt runoff that create abundant surface storage in the form of lakes, wetlands, and beaded streams. These surface water elements compose complex drainage networks that affect aquatic ecosystem connectivity and hydrologic behavior. The 4676 km2 Fishand Creek drainage basin is composed of three watersheds that represent a gradient of theACP landscape with varying extents of eolian, lacustrine, and fluvial landforms. In each watershed, we analyzed 2.5-m-resolution aerial photography, a 5-m digital elevationmodel, and river gauging and climate records to better understand ACP watershed structureand processes. We show that...

Stream physical parameter time series files for six or more beaded streams on the North Slope of Alaska in the Fish Creek Watershed near Nuiqsut. These include time series of water temperature (pool bed and surface and channel runs) and pool stage and correspond stream discharge developed from a rating curve.

The distribution and abundance of fishes across the Alaska Arctic is not well understood. Better information on fish distribution is needed for habitat assessment and modeling activities and is also important for planning industrial activities. The State of Alaska maintains a fish distribution database for anadromous fish species, however there is currently no analog for resident fish species. The concept behind AquaBase was to fill the information gap for resident fish by design a database that contains information about all fish species. AquaBase does not duplicate information that is already available in other spatial database, but rather ‘rescues’ data from reports that are not readily available.

Hydrologic processes greatly influence Alaska’s physical and biological resources and the human communities that depend upon them. These processes will also be greatly impacted by expected changes in climate, including warming temperatures and changing seasonal precipitation patterns and amounts. However, current understanding of those impacts is limited. Improving that understanding is a first step toward assessing how the likely changes in hydrology will impact other physical and biological processes. The Western Alaska LCC and the Alaska Climate Science Center, with support from other LCCs, hosted a workshop of 28 hydrologists, researchers, fisheries biologists, local experts and managers for a workshop structured...

Alaska’s freshwater resources, vitally important for salmon and other species, are vulnerable to changes resulting from climate change. Though temperature is a critical element in the suitability of aquatic habitats, Alaska’s stream and lake temperature monitoring is occurring through independent agencies/partners without a means to link and share data. Because a coordinated network of monitoring data can help scientists and managers understand how aquatic systems are responding to climate change, conducting an inventory of past and present stream and lake temperature monitoring efforts has been identified as a priority science need for Alaska. This project consolidated existing monitoring site locations and attributes...

Hydrologic data for the Alaska Arctic are sparse, and fewer still are long-term (> 10 year) datasets. This lack of baseline information hinders our ability to assess long-term alterations in streamflow due to changing climate. The Arctic LCC is provided stop-gap funding to continue this long time series hydrological data sets in the Kuparuk and Putuligayuk watersheds.

Our overarching questions are: (1) How much of the river water and water-borne constituents (i.e. sediment, nutrients, organic matter) from the Jago, Okpilak and Hulahula rivers are coming from glacier melt? (2) How do inputs from these rivers affect the downstream ecosystems? (3) How will loss of glaciers affect these ecosystems? The study will help elucidate how inputs from glacier-dominated arctic rivers differ from unglaciated rivers, through a combination of ground work, boat work, and remote sensing. In Phase One of this study, we intend to explore the relationship between glaciers and coastal ecosystems. Our goal in this phase-one study is not to answer these questions conclusively but rather improve our...

The USGS and Arctic National Wildlife Refuge Staff operate and maintain a streamgage at Hulahula River near Kaktovik, Alaska. Data from this station is necessary to complement glacier mass-balance studies and provide information necessary to project stream flow regimes under various scenarios of climate change. This project includes operation, acquiring real-time data, analysis of the data, and internet access. The gauge continues to operate as of 2017.

LCC funding for this project helped maintain a network of hydrology monitoring sites in a representative watershed of the Arctic Coastal Plain. The work was conducted within the context of climate change and impending oil and gas activities in the region, the latter of which is the impetus for focusing on the Fish Creek watershed. The project included two monitoring components:1) Beaded Stream & Lake Hydrology Monitoring (dominant habitat type within the watershed): in 6 stream/lake complex watersheds (Redworm, Hannahbear, Blackfish, Crea, Oil, and Bills creeks), continuous water level and temperature (in lakes, streams, and confluences), discrete discharge measurements, and continuous water quality (specific conductivity,...

The Big Bend reach of the central Platte River serves as a major staging area for migratory water birds (waterfowl, wading birds, shorebirds) during spring migration. Reduced spring flows and drought conditions within the Platte system have promoted encroachment by undesirable woody and herbaceous invasive species. This encroachment has caused the once shallow braided channels of the Platte River to incise. This action has significantly reduced available habitat for roosting and loafing Sandhill Cranes, endangered Whooping Cranes, and millions of waterfowl that annually utilize the Platte River each spring. This change in river morphology has also reduced available nesting habitat for the federally listed Interior...

Viable sockeye salmon populations are critical to the economy, culture, and freshwater ecosystems of Bristol Bay in Western Alaska, and it is unclear how populations might respond to warming temperatures during the critical life history stages of spawning and embryo incubation. The overarching goal of the project is to understand how temperature might influence population-specific patterns of embryo incubation, timing of hatching and fry emergence, and sockeye salmon embryo survival. By combining analyses of data from two large lake systems in the Kvichak watershed, laboratory rearing experiments to elucidate functional relationships, and simulation modeling, this project quantifies biological responses to changing...
