Where we are and where we need to be to understand regional water temperature trends: establishing minimum data collection standards for stream temper 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. Many entities are collecting temperature data for a variety of purposes to meet project or agency specific goals. AKOATS, the Alaska Online Aquatic Temperature Site, is a comprehensive statewide inventory of current (n=413) and historic (n=398) continuous monitoring locations for stream and lake temperature using a common set of attributes. Data were gathered from fish biologists, hydrologists, water...

Climate projections for the archipelago indicate probable increases in annual and seasonal air temperature over the next 85 years. Corresponding increases in the temperature of freshwaters also are expected, which may adversely influence the biology of salmon, the quality of salmon habitat, and the availability of salmon to support the ecosystem and economy. It is essential that salmon managers be provided with relevant and reliable information on expected changes in thermal regimes and their influence...

Previous work has demonstrated that a variety of physical and biological processes are sensitive to changing climate regimes in this region, including those that support wildlife and fisheries that are of substantial importance for subsistence and commercial activities. This collaborative project will result in the compilation of a database of existing stream, river and lake temperatures that is unmatched anywhere else in Alaska in terms of its spatial and their temporal coverage. Analysis of these data will result in refinement of the monitoring plan developed to characterize thermal...

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.

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.

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 goal of this effort is to identify current coastal research and management projects that are taking place in Western Alaska and to synthesize information into a report that documents the ‘project landscape’ for communities facing change, decision-makers navigating change, researchers pursuing projects, as well as funding agencies trying to prioritize where to allocate resources. To identify coastal change projects, we first conducted an extensive Internet... Categories: Data; Tags: COASTAL AREAS, COASTAL AREAS, COASTAL HABITAT, COASTAL HABITAT, COASTAL LANDFORMS, All tags...

Consistent with efforts by the United States National Park Service (NPS) at Bering Land Bridge National Preserve (BELA) and Cape Krusenstern National Monument, high quality, defensible digital shoreline datasets are under development for select coastal parks in the State of Alaska. Near BELA, for the area from Cape Prince of Wales to Cape Espenberg, extended revised shoreline coverage can be produced using true color coastal shoreline imagery to update the boundary demarking the mean high water (MHW) shoreline, which represents...

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.

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...
