Guidebook to Permafrost and Quaternary Geology along the Richardson and Glenn Highways between Fairbanks and Anchorage, Alaska

Abstract

metals, minerals, fuels, and geothermal resources; the location and supplies of groundwater and construction materials; the potential geologic hazards to buildings, roads, bridges, and other installations and structures; and shall conduct such other surveys and investigations as will advance knowledge of the geology of Alaska."Address mail orders to the Fairbanks office. DGGS publications may be inspected a t the following locations.

Influences of glacier melt and permafrost thaw on the age of dissolved organic carbon in the Yukon River basin

“…The situation for DOM delivered in ground water (e.g., Tanana River and Clearwater River winter samples) is more complicated since this pool of organic matter can also be influenced by overlying soils and geologic materials such as formations containing shales and coal, which may also supply ancient carbon to the DOC pool. Groundwater-bearing deposits in the Tanana River basin, however, are primarily thick silt, sand, and gravel deposits [Pewe and Reger, 1983]. While the influence of geologic materials is not likely in this scenario, they cannot be discounted at this time.…”

Mass balance, meteorological, ice motion, surface altitude, and runoff data at Gulkana Glacier, Alaska, 1993 balance year

“…However, no flow instabilities have been detected since scientific investigation began in the early 1960's. Gulkana Glacier has been in general recession since the culmination of its last advance around the turn of the century (Pewe and Reger, 1983). The total recession since then has been about 3 km.…”

“…The glacier surface area used for defining the 1993 AAR, 19.3 km2, is the value determined for reporting the 1967 balance data (Tangborn and others, 1977) and has not been updated. The lower glacier has thinned and retreated slightly from 1960to 1973and 1983(Mayo and Trabant, 1986. Since 1983, the lower glacier has continued to thin about 1 m/yr and has probably been accompanied by minor terminus retreat.…”

“…Measurements began on Gulkana Glacier during the early 1960's with the University of Alaska Gulkana Glacier Project (Pewe and Reger, 1983). For several years this project measured the energy budget, mass balance, meteorology, foliation, flow, and glacier bottom topography (from gravity anomalies) at Gulkana Glacier.…”
