This project engaged several Western Alaska coastal communities to describe types and formation processes associated with near-shore sea-ice phenomena during the fall freeze-up season, in particular as relevant to coastal erosion, flooding, and shoreline protection. Commentary and indigenous and local observations were drawn from and analyzed through existing community observing programs (SIZONet and ANTHC-LEO) as well as from new interviews and meetings conducted for this project. Extensive work was performed to summarize, assess, and synthesize written and recorded observations and commentary. A primary result was identification of a range of slush-ice berm events that could be broadly categorized as “advective”...
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 resulting vector data shape files of nearshore bathymetry for Gambell, Savoonga, Golovin, Wales, Shismaref, and Hooper Bay are available by following the link below.

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 project used existing ShoreZone coastal imagery to map 719 km of shoreline in Bristol Bay, from Cape Constantine to Cape Newenham. This section of coastline is an extremely important herring spawning area and an important component of the Bristol Bay fisheries. Intertidal and nearshore vegetation, on which herring spawn, was catalogued as part of the mapping and, along with shore types, coastal substrate, and coastal biota, added to the state-wide ShoreZone dataset.

A high spatial resolution storm surge model was developed for the YK Delta area to assess biological impacts of storm surges under current and future climates. Storm surges are expected to be more frequent and more severe in the YK Delta area due to climate change and sea level rise. The biological impacts in the YK Delta due to the changed storm surges could be extreme.The model was assessed with respect to measured water level data at the coast and, where available, spatial extent of inundation, for 6 storms from the period 1992 to 2011. In total, inundation projections from 9 historical storms (5 from the assessment + 4 others) were developed. For each storm, an spatial inundation index (time-integral of water...

Water temperature influences all biological and physicochemical interactions within aquaticsystems. Water temperature monitoring is an essential part of lake management capable of providing early warning signs of climate change using straight-forward, low-cost techniques. Water temperature data acquired in this study will be used to support analyses of trend of the lacustrine component of sockeye salmon habitat. The need for such analyses is acute because climate change will influence lake habitat quality; growth and survival of juvenile sockeyesalmon; and subsistence, recreational, and commercial harvest opportunities. Additionally, data acquired in this project will be eventually combined with data collected by...

The caribou populations of southwest Alaska have declined precipitously over the past decade or more, and the total population of this expansive region currently is 80% below the populations of the late 90’s to early 2000’s. This research is a collaborative effort among the principal managers of this resource to directly address the causes of this decline.The goals of this project was to mechanistically link climate, soil N cycling, plant morphological and nutritional phenology, and caribou population dynamics, by collecting high-quality information to knit together ecosystem function across several trophic levels and at a range of spatial and temporal scales.

This project used previously collected ShoreZone imagery to map nearly 1,600 km of coastline between Wales and Kotzebue. With additional mapping supported by the Arctic LCC and National Park Service, this effort completed the Kotzebue Sound shoreline, which now has been included in the state-wide ShoreZone dataset. The complete ShoreZone dataset for the region was used to conduct a coastal hazards analysis and create maps that identify areas undergoing rapid coastal erosion and areas that are sensitive to inundation by storm surge and sea level rise.
This project provided systematic coastal habitat imagery and mapping for the Alaska Peninsula shoreline following the Alaska ShoreZone Mapping Protocol and made these products web-accessible. The completed mapping product is available on the ShoreZone website in a searchable dataset. Individuals and communities can query coastal habitat information for use in coastal zone planning. Mapped features include features such as shore types and morphology (e.g., dunes, beaches, and estuaries), intertidal biota (e.g., salt marshes, eelgrass beds, kelp beds) and man-made features (e.g., seawalls, docks). In addition to the dataset, the web-accessible, high resolution low-tide imagery (video and photos) complement the mapped...

As Alaskans continue to feel the impacts of a changing climate, the need for resource managers to understand how these changes will alter aquatic systems and fisheries resources grows. Water temperature data collection has increased in recent years to begin to fill our gaps in knowledge about current thermal profiles; however, with Alaska’s vast landscapes and ubiquitous freshwater habitats, the need for water temperature data is ongoing. Many entities are collecting temperature data for a variety of purposes to meet project or agency specific goals. Statewide interest in thermal patterns and increasing data collection efforts provides Alaska’s scientific and resource managing community an opportunity to meet broader...

Researchers have consistently prioritized the need to measure the status and trends of stream and lake temperatures across Alaska landscapes, and to compile those data for predictive modeling. The goal of this project is to develop an open statewide water temperature network with easily understood and readily implemented data standards to support landscape-level assessments. Development of two-tiered data standard will allow data collectors and data managers the flexibility to use their existing agency protocols, yet set standards that are scientifically robust and suitable for landscape-level analysis.
The Bristol Bay region represents an area of transition between the maritime climate of the southern coast and the continental climate of the Interior and Copper River Basin. These regions are largely protected by mountains areas and do not have a strong maritime influence. Temperatures are moderate and sea ice does form in the Bristol Bay but complete freeze-up of these waterways is not common. Low winter temperatures are below 0 degrees F with events below -20F. Summer temperatures are generally in the mid 60s with only a few days above 80. Highest precipitation is in August and September (Shulsky and Wendler 2007). The following table is a scoping tool that can be used to begin to evaluate community vulnerability...

This report documents climate change impacts and potential impacts as described by the local people and interpreted through the lens of public health. It is the sixth report in a series describing climate change across Alaska, and the first report to focus on the Bristol Bay Region. In the Yupik and Aleut community of Pilot Point residents report changes to the weather, landscape, plants and wildlife. Extreme weather events are thought to be more common, the timing of seasons is more unpredictable, erosion to shorelines is occurring at a rapid rate, and consequentially, vulnerability to flooding is increasing. Identified health concerns include food security, damage to health-critical infrastructure, injury and...

Lack of complete snow cover for the past 3 winters in southwestern Alaska has forced agencies to postpone conducting moose surveys due to the likelihood of underestimating the population/lack of comparability to previous surveys. Poor snow conditions are known to 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, research was initiated to estimate sightability correction factors (SCFc) to apply to abundance estimates.

The objective of this project was to produce an Alaskan Existing Vegetation Type (AKEVT) map at 30m resolution for a portion of the Western Alaska Landscape Conservation Cooperative (WALCC) region using a very consistent (2000 +/- 1 yr.) remote sensing data set (Landsat 7 ETM+) and the same methodology. The mapped area encompasses the western and northern parts of the WALCC region, plus the Kodiak Archipelago. The legend was based on grouping the Alaska Vegetation Classification (Viereck, et al. 1992) Level IV classes to exclude the differences in vegetation height and canopy closure. Three major types of data were utilized; field plot data, Landsat 7 ETM+ spectral data, and environmental variables. All of the available...

This project resulted in an extensive mapping of coastal change along the entire coastline of the Western Alaska Landscape Conservation Cooperative (LCC). The work provides important baseline information on the distribution and magnitude of landscape changes over the past 41 years. The extent of change to the coastline and to coastal features, such as spits, barrier islands, estuaries, tidal guts and lagoons, was known to be substantial in some areas along the coast (e.g., portions of the Yukon–Kuskokwim Delta), although the extent of change along the full Bering Sea coast was not well documented. With this analysis, changes can be summarized for different land ownerships or other units to assess the extent of recent...
