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 uses 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 will complete the Kotzebue Sound shoreline, which will be included in the state-wide ShoreZone dataset. The complete ShoreZone dataset will be 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.

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.

This project uses 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, will be catalogued as part of the ShoreZone mapping and, along with shore types, coastal substrate, and coastal biota, added to the state-wide ShoreZone dataset.
