Map showing the depth to the base of the deepest ice-bearing permafrost as determined from well logs, North Slope, Alaska
T. S. Collett, K. J. Bird, K.A. Kvenvolden, L. B. Magoon
1989, Oil and Gas Investigation Map 222
Because gas hydrates from within a limited temperature range, subsurface equilibrium temperature data are necessary to calculate the depth and thickness of the gas-hydrate stability field.  Acquiring these data is difficult because drilling activity often disrupts equilibrium temperatures in the subsurface, and a well mush lie undisturbed until thermal equilibrium...
Alaska Interim Land Cover Mapping Program; final report
Katherine Fitzpatrick-Lins, E.F. Doughty, Mark Shasby, Susan Benjamin
1989, Open-File Report 89-128
In 1985, the U.S. Geological Survey initiated a research project to develop an interim land cover data base for Alaska as an alternative to the nationwide Land Use and Land Cover Mapping Program. The Alaska Interim Land Cover Mapping Program was subsequently created to develop methods for producing a series...
Simulation of ground-water flow at Anchorage, Alaska, 1955-83
Leslie Patrick, T. P. Brabets, R. L. Glass
1989, Water-Resources Investigations Report 88-4139
The groundwater system at Anchorage, Alaska was analyzed by using a two-layer three-dimensional mathematical model. By use of existing data, both nonpumping and pumping steady-state conditions and transient conditions were simulated. Under steady-state conditions, calculated directions of groundwater flow were similar to observed flow patterns, and calculated stream discharges generally...
Preparation of average annual runoff map of the United States, 1951-80
W.R. Krug, W.A. Gebert, D.J. Graczyk
1989, Open-File Report 87-535
Average annual runoff was computed or estimated for 2,148 hydrologic cataloging units in the United States and Puerto Rico , for the period 1951-80. Runoff was computed from the recorded streamflow at 5,951 U.S. Geological Survey gaging stations. The runoff at more than 3,000 of these stations was estimated by...
