Global environmental change has influenced lake surface temperatures, a key driver of ecosystem structureand function. Recent studies have suggested significant warming of water temperatures in individual lakesacross many different regions around the world. However, the spatial and temporal coherence associatedwith the magnitude of these trends remains unclear. Thus, a global data set of water temperature isrequired to understand and synthesize global, long-term trends in surface water temperatures of inlandbodies of water. We assembled a database of summer lake surface temperatures for 291 lakes collectedin situ and/or by satellites for the period 1985–2009. In addition, corresponding climatic drivers (airtemperatures,...

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...

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...

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...
The Western Alaska LCC was one of the second tier LCCs to get established (officially started in 2011). With funding from FWS, Western AK LCC staff were hired in 2010 and they held a series of nine (9) meetings in October and November 2010 throughout the western Alaska region to speak with potential partners and solicit input on early directions for the LCC. Meetings were held in Cold Bay, King Salmon, Dillingham, Anchorage, Kodiak, Bethel, Fairbanks, Kotzebue, and Nome. Over 100 people participated in the series of local meetings, including representatives of federal and state agency staff, non-‐profit organizations, Alaska Native Tribes and organizations, academia, and local residents. The Arctic Research Consortium...
These raster datasets represent historical stand age. The last four digits of the file name specifies the year represented by the raster. For example a file named Age_years_historical_1990.tif represents the year 1990. Cell values represent the age of vegetation in years since last fire, with zero (0) indicating burned area in that year. Files from years 1860-2006 use a variety of historical datasets for Boreal ALFRESCO model spin up and calibration to most closely match historical wildfire dynamics.

These raster datasets are output from the Geophysical Institute Permafrost Lab (GIPL) model and represent simulated active layer thickness (ALT) in meters averaged across a decade. These data were generated by driving the GIPL model with a composite of five GCM model outputs for the A1B emissions scenario. The file name specifies the decade the raster represents. For example, a file named ALT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated maximum depth (in meters) of thaw penetration (for areas with permafrost) or frost penetration (for areas without permafrost). If the value of the cell is positive, the area is underlain by permafrost and the cell value specifies the depth...
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 purpose of the research is to develop a storm surge model for the YK Delta area and to apply it to determine biological impacts of storm surges in the current and future climates. This research is needed as 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. With the model, we will study 10 storms over the 1980 – 2011 time period. Model output will be used to determine the recurrence interval for the individual storms. With the model output from individual storms, an inundation index (time-integral of water level during a storm) will be calculated....

The Western Alaska LCC, the Department of Interior’s Alaska Climate Science Center and the Bureau of Land Management brought together 150 land and resource managers, field specialists, researchers and local knowledge experts to identify climate change related priority science/information needs for land and resource management in western Alaska. The workshop results help inform development of the LCC’s Science Strategy, which will guide the LCC’s efforts over the next ten years. The workshop was modeled in part after the 2007 WildREACH Workshop for the arctic region. Attendance was by invitation; workshop organizers sought diverse cross-program and cross-agency participation.

These rasters represent estimated potential evapotranspiration (mm). Data were generated by using the Hamon equation and air temperature projections from the ECHAM5 model under the A1B emissions scenario.
The Arctic LCC and National Park Service has partnered together to complete a ShoreZone imagining and mapping project for the entire coastline, lagoons inclusive, from Point Hope to Wales in Northwestern Alaska. The ShoreZone Mapping System uses oblique aerial imagery and field data from ShoreStations to classify coastline habitats based on geological and biological attributes. ShoreZone products are made available to the public through the National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Website.

The Yukon-Kuskokwim Delta of Alaska is a globally important region for numerousavian species including millions of migrating and nesting waterbirds. Climate change effectssuch as sea level rise and increased storm frequency and intensity have the potential to impactwaterbird populations and breeding habitat. In order to determine the potential impacts of theseclimate-mediated changes, we investigated both short-term and long-term impacts of stormsurges to geese and eider species that commonly breed on the Yukon-Kuskokwim Delta. Todetermine short-term impacts, we compared nest densities of geese and eiders in relation to themagnitude of storms that occurred in the prior fall from 2000–2013. Additionally, we modeledgeese...

This report is structured around the specific objectives in the format of three stand-alone manuscripts that are in the process of submission to peer-reviewed journals. The first manuscript includes objectives 1-2, the second manuscript addresses objective 3, and the final manuscript objective 4. The overarching goal of the proposal was to understand how both recently experienced and projected water temperatures might influence population-specific patterns of embryo incubation, timing of hatching and fry emergence, and survival of sockeye salmon embryos. Additionally, we sought to explore the potential for adaptation in a heritable threshold life history trait that shapes whether an individual migrates to the ocean...
Through a grant from the US Fish and Wildlife Service on behalf of the Western Alaska Landscape Conservation Cooperative (WALCC), we have developed a comprehensive statewide inventory of current and historic continuous monitoring locations for stream and lake temperature. This project is one component of the LCC’s strategy to help partners understand and prepare for potential climate impacts to freshwater systems across Alaska.This project compiled a statewide catalog of monitoring locations using a common set of attributes. The inventory is fully accessible via an online mapping interface or it can be viewed and queried directly within commercial GIS software. Future LCC projects will entail gathering the aquatic...

Webinar 2015: Alaska’s National Hydrography Dataset (NHD), the digital data layer that depicts the location of lakes and streams, was originally created from the 1950’s topographic maps. With funding support from the LCC Network, this project focused on establishing a statewide framework to improve the hydrography mapping and stewardship in Alaska. This will be achieved 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...

Climate change is expected to impact the thermal regimes of streams and otherfreshwater ecosystems (Schindler 2001, Malmqvist and Rundle 2002, Poff et al. 2002). Whileincreased air temperatures will have direct effects on water temperature, indirect effects due tochanges in precipitation patterns, groundwater characteristics, and flow regimes (Perkins et al.2010) may have much larger effects. We explored 1) how variation in hydrologicalcharacteristics of streams mediate their thermal regimes, 2) how geomorphic features ofwatersheds regulated stream water sources and, therefore, thermal characteristics, and 3) whetherpatterns of thermal variation among streams correlate with the life-history characteristics ofPacific...
