The Jago, Okpilak, and Hulahula rivers in the Arctic are heavily glaciated waterways that are important for fish and wildlife as well as human activities including the provision of food, recreation, and, potentially, resource extraction on the coastal plain. If current glacial melting trends continue, most of the ice in these rivers will disappear in the next 50-100 years. Because of their importance to human and natural communities, it is critical to understand how these rivers and their surrounding environments will be affected by climate change and glacier loss. The overarching goal of this project was to research (1) the amount of river water, sediment, nutrients, and organic matter in the Jago, Okpilak, and...
Abstract: P-band interferometric synthetic aperture radar (InSAR) data at 5 m resolution from Kahiltna Glacier, the largest glacier in the Alaska Range, Alaska, USA, show pronounced spatial variation in penetration depth, δ P. We obtained δ P by differencing X- and P-band digital elevation models. δ P varied significantly over the glacier, but it was possible to distinguish representative zones. In the accumulation area, δ P decreased with decreasing elevation from 18±3 m in the percolation zone to 10±4 m in the wet snow zone. In the central portion of the ablation area, a location free of debris and crevasses, we identified a zone of very high δ P (34±4 m) which decreased at lower elevations (23±3 m in bare ice...

This dataset includes Snow Free Date(sfdy) for northern Alaska in GeoTiff format, covering the years 1980-2012. Snow Free Date is defined as day of the end of the core snow period(day of year). The core snow season is defined to be the longest period of continuous snow cover in each year. The dataset was generated by the Arctic LCC SNOWDATA: Snow Datasets for Arctic Terrestrial Applications project.“Day-of-year” (doy) output is expressed in Ordinal dates (“1” on 1 January, and “365” on 31 December). Dates have not been corrected for leap years. This output is appropriate for display purposes, as it is readily interpreted as calendar day of year. It is not recommended as input for analysis, as it may produce incorrect...

This dataset includes Snow Depth(snod) for northern Alaska in GeoTiff format, covering the years 1980-2012. Snow Depth is defined as depth on 1 March(m). The dataset was generated by the Arctic LCC SNOWDATA: Snow Datasets for Arctic Terrestrial Applications project.The dataset is delivered in the ZIP archive file format. Each year is output in a separate GeoTiff file, where the year is indicated by the filename.Over the last 20 years, under a variety of NOAA, NSF, and NASA research programs, a snow-evolution modeling system has been developed that includes the MicroMet micrometeorological model, the SnowModel snow-process model, and the SnowAssim data assimilation model. These modeling tools can be thought of as...

Glacier Bay National Park and Preserve, Alaska. Buried tree trunks exposed on west shore of Glacier Bay north of Berg Inlet. 1906.

Album caption. Toe of Fourth Glacier toward the southeast Whiskey Ridge, a truncated spur, exposing (Jurassic) Naknek formation. Stratified pumice in terrace remnant in center of photo appears to match high terrace behind camp. It is plastered against the glacier margin in such a manner as to indicate that there has been no movement of the margin since pumice deposition. Uppermost south-bank tributary of Knife Creek emanating from 3-foot-wide gorge through welded tuff. Note heavy mantle of pumice on the lying glacier. Katmai, Southwest Alaska. Photo taken: 7/6/53. 4 x 5 ¼.

Nisqually Glacier, from confluence with Wilson Glacier to the nunatak, as seen from station 7 on August 22, 1945. Upper part of glacier is at about its lowest known ice mass, as evidenced by the exposure of bedrock. There is almost no crevassing in middle reach. Slope at center of photo is very flat and broken below there. Note the lightcolored medial moraine approaching nunatak from upper right. Sources of debris may be deduced. Note also large icecored moraine along wrest edge of glacier. Mount Rainier National Park. Pierce County, Washington. August 22, 1945. Panoram in two parts. Photo 3 and 4. (see vfm00004) Published as figure 4 in U.S. Geological Survey. Professional paper 631. 1969.

Upper reaches of Nisaqually and Wilson Glaciers as seen from station 13 on August 30, 1957. Most of exposed bedrock areas marked in photo no. 18 are now covered by Wilson Glacier. Glacier surface at profile 3 is only 3 feet (1 m) higher than in 1949, but near left edge of picture it probably is about 60 feet (18 m) higher because at profile 2 the ice level rose 97 feet (30 m) from 1949 to 1957. The crevassing appears much coarser (rougher) now and extends to the east edge of the glacier. Exposed face of the ice field above the cliff is thicker. The falls at far left are nearly dry (compare with photo no. 18). Note the different layers (ages) of firn exposed in the small area at lower right, which can be differentiated...

Album Caption: Mount Rainier National Park, Washington. Aerial view of down-valley part of avalanche deposits. Rock fragment shown in photo is circled. Photo by A.S. Post, August 20, 1964. Pierce County, Washington. Published in U.S. Geological Survey Bulletin 1221-A, figure 6. 1965.

Photograph illustrating how temporary lakes are caused by periodically surging glaciers: Tikke Glacier at beginning of surge. Tikke Glacier, located north of Glacier Bay, is subject to periodic surges in which the ice suddenly advances several kilometers at approximately 20-year intervals. This view of the glacier was taken when a surge was moving rapidly down the glacier. Lateral valleys to the right of the glacier do not contain lakes: farther up glacier on the left side the fast-moving ice recently has dammed the lateral streams. British Columbia, Canada. August 1965. Published on sheet 3 of U. S. Geological Survey. Hydrologic investigations. Atlas HA-455. 1971.

A September 3, 2000, north-looking photograph taken from near the head of Harvard Arm, College Fiord, Prince William Sound, Chugach National Forest, Alaska. The photograph shows the advancing terminus of Harvard Glacier at the head of the fiord. Baltimore Glacier, a retreating hanging glacier is at the left side of the photo. Compare with a 1909 photograph from the same location - gus00208.
