D.A. Cacchione, D.E. Drake, P. Wiberg
1982, Geologie en Mijnbouw (61) 71-78
We have used long-term measurements of near-bottom velocities at four heights above the sea floor in Norton Sound, Alaska, to compute hourly values of shear velocity u., roughness and bottom-drag coefficient. Maximum sediment resuspension and transport, predicted for periods when the computed value of u. exceeds a critical level, occur...
Simulations of seabird damage and recovery from oilspills in the northern Gulf of Alaska.
W.B. Samuels, K.J. Lanfear
1982, Journal of Environmental Management (15) 169-182
If an oilspill contacts a colony of glaucous-winged gulls Larus hyperboreus, reducing the population by 50%, the population is expected to recover to its pre-spill level in c.20 yr. For common murres Uria aalge, this same situation yields a recovery time of c.70 yr. Assuming that oil is found in...
Leachability of uranium and other elements from freshly erupted volcanic ash
D. B. Smith, R. A. Zielinski, W.I. Rose Jr.
1982, Journal of Volcanology and Geothermal Research (13) 1-30
A study of leaching of freshly erupted basaltic and dacitic air-fall ash and bomb fragment samples, unaffected by rain, shows that glass dissolution is the dominant process by which uranium is initially mobilized from air-fall volcanic ash. Si, Li, and V are also preferentially mobilized by glass dissolution. Gaseous transfer...

Rifting history and structural development of the continental margin north of Alaska
Arthur Grantz, S. D. May
1982, Book chapter, M 34: Studies in continental margin geology
Seismic-reflection profiles in the Alaskan Beaufort Sea and onshore geology indicate that the continental margin north of Alaska is of Atlantic type. Rifting appears to have begun in earliest Jurassic time, about 190 to 185 m.y. ago, when crustal extension created a rift-valley system beneath the Beaufort shelf and part...

Dated wood from Alaska and the Yukon: Implications for forest refugia in Beringia
D.M. Hopkins, P.A. Smith, J.V. Matthews Jr.
1981, Quaternary Research (15) 217-249
Postulations on the existence of forest refugia in parts of Beringia during the last glacial have been, in large part, based on ambiguous evidence. Existing data on radiocarbon-dated and identified fossil wood and macrofossils from Alaska and northwest Canada are synthesized here and are augmented by results of palynological studies...
Gravitational potential as a source of earthquake energy
L. Barrows, C.J. Langer
1981, Tectonophysics (76) 237-255
Some degree of tectonic stress within the earth originates from gravity acting upon density structures. The work performed by this "gravitational tectonics stress" must have formerly existed as gravitational potential energy contained in the stress-causing density structure. According to the elastic rebound theory (Reid, 1910), the energy of earthquakes comes...
