Alaska Yukon-Kuskokwim Delta Aerial Survey Duck Analysis Strata This GeoPackage contains the analysis strata (“YKD_AnalysisStrata”) used in calculating population indices for ducks, loons, mergansers, grebes, gulls, and terns. This layer was created from the file (“YKD_DesignStrata”) when the existing rotating panel design was developed in 1999. This layer was originally created as an ArcInfo coverage, saved to a shapefile, and imported to SQLite Database format.

The lifespan calculation is based on estimated sediment supply and sea-level rise (SLR) predictions after Ganju and others (2020). Sea level predictions are local estimates which correspond to the 0.3, 0.5, and 1.0 meter increase in Global Mean Sea Level (GMSL) scenarios by 2100 from Sweet and others (2022). The U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing Federal, State, and local managers with tools to estimate the vulnerability and ecosystem...

Resource managers in the Southwest are faced with making natural resource and fire management decisions now, despite a lack of accessible information about how those decisions will play out as fire regimes, and their associated disturbances, will change across the landscape. Decision makers in natural-resource management increasingly require information about projected future changes in fire regimes to effectively prepare for and adapt to climate change impacts. An accessible and forward-looking summary of what we know about the “future of fire” is urgently required in the Southwest and across the country...

Collection, Kane County, Utah, Photographers, photo print Alaska Yukon-Kuskokwim Delta Aerial Survey Raw Track Files Aerial survey track files were recorded by each observer using Panasonic Toughpad or Toughbook computers running the software program “RECORD” (John I. Hodges, MBM-Alaska). The RECORD program was activated during the survey before arriving at the first transect and shut down after the last transect was completed, prior to engine shut-down. “Raw” track files recorded the flightpath of the aircraft including the area surveyed on each transect. GPS coordinates were captured every five seconds using a recreational grade receiver with an estimated positional accuracy of 5-10 meters after the software program was activated. These raw track files have not been quality checked, so they may contain missing or erroneous coordinates...

Typically, the EAG estimates are publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contains five fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) Field Brome (Bromus arvensis); 4) medusahead (Taeniatherum caput-medusae); and 5) Sandberg bluegrass (Poa secunda).
