Western Alaska is one of the fastest warming regions on the globe and recent trends are expected to continue into the next century, likely having substantial effects on the aquatic resources of this region. While increased air temperatures will have direct effects on water temperatures, indirect effects due to changes in precipitation, groundwater characteristics, and flow regimes may have much larger effects on aquatic ecosystems. Coastal watersheds of Western Alaska are expected to receive 25-50% more snow and 18-25% more rain in the next century. Future “climate warming” may actually cool some streams if the ratio of snow to rain increases for coastal watersheds, while rain-dominated streams are likely to become...
Thermal response of western Alaska lakes and lagoons to past, present, and future changes in climate
Water temperature in lakes and lagoons plays a key role in hydrology, water quality, and habitat suitability for aquatic organisms. The purpose of this project is to provide land and resource managers with information related to the past, present, and future temperature trends in lake surface waters in western Alaska. Through a combination of remote sensing, in situ data collection, model development, we will analyze similarities and differences related to spatial and temporal patterns of lake surface temperatures in western Alaska from 1985 to 2100.
The Bureau of Ocean Energy Management (BOEM) is supporting a field effort in support of a ShoreZone mapping project along the Chukchi and Beaufort coasts. Funds from the LCC will allow for the inclusion of three additional ShoreStations. Researchers will conduct ground surveys to get detailed physical and biological measurements throughout the various and often unique Chukchi and Beaufort coastal habitats. Sediment samples will be archived from each shore station for hydrocarbon analyses in the event of a local or regional oil spill. The Arctic ShoreZone Shore Stations will be added to the statewide database and made available online to the public NOAA website.

Understanding the causes of relative sea level rise requires knowledge of changes to both land (uplift and subsidence) and sea level. However, measurements of coastal uplift or subsidence are almost completely lacking in western Alaska. This project will result in precision measurements of prioritized benchmarks across the Western Alaska geography. This will improve the network of published tidal benchmark elevations, allowing for tidal datum conversion in more places, and providing a necessary component for improved inundation studies in coastal communities and low-lying areas.
This project is focused on establishing a statewide framework to improve the hydrography mapping and stewardship in Alaska. This will be acheived through the creation of a statewide system to make digital mapping data updates accessible and affordable, and through the creation of a statewide hydrography mapping coordinator position to synchronize updates and guide hydrography mapping development. This framework will allow agencies and organizations to greatly improve their hydrography mapping data, as well as consume and uplift project level hydrography data that would not otherwise be incorporated.
Permafrost thaw can be a major driver of landscape change. Regions in Western Alaska are highly vulnerable to such thawing due to the high ice content of the soils and the lack of thermal monitoring in this region has limited our ability to understand current thermal state and establish thawing rates. This study established a permafrost monitoring network in this region, providing a baseline of permafrost thermal regimes for assessing future change at a total of 26 automated monitoring stations. Stations have collected year-round temperature data from the active layer and the permafrost starting from the summer of 2011. The strong correspondence between spatial variability in permafrost thermal regime and an existing...
Concern about invasive species in Alaska is a growing concern, attracting attention from land managers, politicians and the public. Nearly half the new discoveries of invasive plants, animals, and insects in the state are reported by concerned individuals with a general interest in invasive species. The development of a mobile application for invasive plant identification and reporting will help enable the public to gather and share new invasive plant discoveries. This project will result in the development of a decision tool for identifying non-natives plant species, which will provide the foundation for the app. Project staff will also review user-submitted requests for identification assistance, review app-generated...
To assess the vulnerability of a region to invasive plants, documentation of the presence or absence of invasive plants is necessary. This project expands on work initiated by the EPA to identify invasive plants in rural communities in the Bristol Bay region. Between the two efforts, 26 villages will be inventoried for invasive plant species; this will provide both an essential baseline for understanding the potential impact from these plants and the opportunity to treat the existing populations before they invade new areas. The second part of the project will use these data to assess the vulnerability of important subsistence plants (blueberry and low-bush cranberry) to changes in pollination, as key insect species...

The Yukon-Kuskokwim Delta (YKD) encompasses the southernmost, warmest parts of the arctic tundra biome and is renowned for its high biological productivity and large subsistence-based human population. Ice-rich permafrost currently is widespread and strongly influences terrestrial and aquatic habitats, including local topography, vegetation, soil hydrology, and the water balance of lakes. Ground temperatures are near the freezing point, however, and recent projections indicate that the YKD is poised for widespread loss of permafrost by the end of this century. This has implications for the region’s extensive and heretofore stable terrestrial and aquatic habitats. Tundra wildfire is a common ecological “pulse” disturbance...

Caribou are an important source of food for residents of western Alaska, but as environmental conditions and migration patterns change, some local hunters have encountered difficulty accessing the Mulchatna caribou herd (MCH). Existing data describe MCH harvests, herd movements, and caribou abundance through time, but an investigation drawing from traditional ecological knowledge (TEK) has not occurred. This project will integrate TEK with existing knowledge of caribou movements and subsistence harvests. Targeted stakeholders include local tribes, including Bristol Bay Native Association (BBNA), local village councils, the United States Fish and Wildlife Service, Lake Clark National Park and Preserve (LCNP), and...

The coastal areas of the Yukon and Kuskokwim River Deltas (YKD) are among the most productive in Alaska. The fish, wildlife, and plant resources have been an integral part of communities in this region for thousands of years. Some of the same traits that make it so productive also make it a challenging place to live and work. To better understand and plan for coastal erosion and storm surges, or plan for roads and trails, information about elevation patterns on the YKD are needed. Current topographic maps have limited value given the flatness of the area. A group of partners worked together with USGS to collect elevation information and create a map that will reveal a portion of the delta’s topography. Kodiak Mapping...
Mid-winter icing events have the potential to lead to population declines of grazing caribou and to some species of small mammals due to reduced survival and reproduction associated with restricted access or lack of forage. Population-level effects of icing events remain unclear partly due to limited information on icing events in Alaska. The assessment results provide a baseline data set and remote sensing method, both of which have broad applicability, allowing the community of users to better understand the recent past, better link changes in ecological drivers and responses of wildlife populations, and aid in planning for the future.
Nearshore bathymetry is a vital link that joins offshore water depths to coastal topography. Seamless water depth information is a critical input parameter for reliable storm surge models, enables the calculation of sediment budgets and is necessary baseline data for a range of coastal management decisions. Funding from the Western Alaska LCC resulted in the purchase of field equipment capable of shallow water measurements in rural settings, allowing collection of nearshore bathymetry around western Alaska communities.

The tundra biome is the dominant terrestrial ecosystem of the circumpolar north, and its fate in a rapidly changing climate is of high scientific and socioeconomic concern. One of those concerns is that the majority of caribou herds throughout the circumpolar north are declining, perhaps as a result of climate change. The principal objective of this research is to reveal the connections between soil nutrient cycling, forage quality and caribou habitat selection. This framework is underpinned by the concept that tundra ecosystem productivity is ultimately driven by the thermodynamics of the system induced by climate. In winter, soil microbial processes drive N mineralization and thus N available for plant growth...

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 will consolidate existing monitoring site locations and...
Lack of complete snow cover for the past 3 winters in southwestern Alaska has forced agencies to postpone moose surveys due to the likelihood of underestimating the population/lack of comparability to previous surveys. Poor snow conditions lower the sightability of moose, yet, for most regions of Alaska, the variation in moose sightability during suboptimal conditions has not yet been quantified. Because scientists are predicting less snowfall in this region over the long term, we initiated research to estimate sightability correction factors (SCF_c) using radiocollared animals to apply to abundance estimates obtained via the GeoSpatial Population Estimator (GSPE) method. The Project Goal is to develop a model that...
This project supports the technical development of a mobile application for identifying and reporting invasive plant species in Alaska. It will result in a portable, digital version of a field guide that can be easily updated and that supports integration of reports into the Alaska Exotic Plants Information Clearinghouse (AKEPIC). Under development for both Android and iOS operating systems, the app has the potential to increase the public’s knowledge of invasive plants, as well an improve opportunities for reporting new occurrences.

The western coastline of Alaska is highly susceptible to coastal storms, which can cause coastal erosion, flooding, and have other pernicious effects to the environment and commercial efforts. The reduction in ice coverage due to climate change could potentially increase the frequency and degree of coastal flooding and erosion. Further, estuaries and delta systems act as conduits for storm surges, so when there is less nearshore ice coverage, these systems could introduce storm surge into terrestrial environments unaccustomed to saline intrusion, flooding, or other alien biogeochemical factors.This project quantified the effect of reduced nearshore ice coverage on coastal flooding. The project developed a large...
