The western coast of Alaska is a remote region, rich in wildlife and providing critical nesting habitat for many of Alaska’s seabirds. It is also home to indigenous communities who rely upon the region’s natural resources to support a traditional lifestyle of hunting, gathering, and fishing. Although the region is frequently subject to extensive inland flooding from Bering Sea storms, little is known about the extent and frequency of flooding and its impacts on vegetation, wildlife, and water quality. Furthermore, information is lacking about how climate change and sea-level rise (which can influence the frequency and intensity of storms and subsequent flooding) are affecting this area, its communities, and their...

Participatory mapping is a general term applied to activities that work with participants to gather and map spatial information to help communities learn, discuss, build consensus, and make decisions about their communities and associated resources (NOAA 2015). Here we used participatory mapping to document the locations of different species of berries and understand any social, ecological, or climatological reasons that these locations may be shifting. Mapping was accomplished using topographic basemaps of the villages and surrounding areas overlaid with mylar sheeting. The area surrounding the villages of Hooper Bay and Kotlik were represented with arrays of 1: 63,360 USGS quadrangle topographic maps (USGS, 2017)....
Between 1979 and 1982, the Alaska Division of Geological & Geophysical Surveys (DGGS) and the Geophysical Institute, University of Alaska Fairbanks, undertook an assessment of the states geothermal resources under a program jointly sponsored by the U.S. Department of Energy and the State of Alaska. During this period, reconnaissance investigations of more than 100 thermal spring sites and fumarole fields located in Alaska were conducted by DGGS.
To determine the current spatial distribution of waterfowl nesting areas and understand the importance of environmental variables in the selection of nest locations, we modeled nest densities for six species of geese and eiders that commonly breed on the Yukon-Kuskokwim Delta, including cackling goose ( Branta hutchinsii minima), emperor goose ( Chen canagica), black brant ( B. bernicla nigricans), greater white-fronted goose ( Anser albifrons frontalis), spectacled eider ( Somateria fischeri), and common eider ( S. mollissima). The data used were from U.S. Fish and Wildlife Service's long-term waterbird monitoring program in which single-visit nest searches were conducted during incubation (typically from early...
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 development decisions. Bathymetric data collection capabilities of an active coastal geohazard field program operated by the Alaska Division of Geological & Geophysical Surveys (DGGS) were expanded in 2012. Resultant datasets presented in this report include nearshore bathymetric measurements of critical shallow-water coastal areas in the vicinity of six western Alaska communities: Gambell, Golovin, Hooper Bay, Savoonga, Shishmaref,...
