This project 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 ecotype map allowed for the development of a map of ‘permafrost thermal classes’ for the broader study region. Further, the annual temperature data was used to calibrate models of soil thermal regimes as a function of climate, providing estimates of both historic and future permafrost thermal regimes...

This dataset provides an orthorectified aerial photo mosaic derived from airborne fodar data acquired in 2021 on August 31 over the Totatlanika River in central Alaska. The term “fodar” is a portmanteau of foto and lidar, coined by Matt Nolan, which describes a method of quantifying the color and elevation of Earth’s surface via airborne small-format digital camera photography.

Collection of photographs taken during PRISM field work on the Arctic National Wildlife Refuge. Photos include those taken of habitat within rapid survey plots (usually taken at the northwest corner of the rapid survey plot boundary), completed datasheets, and by crew members. Directories include ANWR_PRISM_plot_photos, ANWR_PRISM_datasheet_photos, ANWR_PRISM_other_photos. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including...

Photos include those taken of completed chick monitoring datasheets by year.Information for the Utqiagvik chick monitoring study were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these files is also contained within the Utqiagvik shorebird project archive (file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_009_Utqiagvik_shorebird_project). If there are discrepancies between the files please use the information contained within the Utqiagvik shorebird project files.

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...

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...

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 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.

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.
