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...
Gravity anomaly and interpretation map of the Chignik and Sutwik Island quadrangles, Alaska
J. E. Case, D.F. Barnes, R. L. Detterman, R. L. Morin, R. F. Sikora
1981, Miscellaneous Field Studies Map 1053-J
The gravity field of the Chignik and Sutwik Island quadrangles near the center of the Alaska Peninsula represents a complex series of transitions between probable continental crust on the north, probable oceanic crust on the south, sedimentary basins on each side of the peninsula, and a central structural high and volcanic arc. The resulting gravity field...

An annotated bibliography of literature on Alaska water birds
Colleen M. Handel, Margaret R. Petersen, Robert E. Gill Jr., Calvin J. Lensink
1981, FWS/OBS 81/12
The demand for information on birds in Alaska has surged within the past few years, primarily because of the need to adequately assess the impacts of a wide range of planned developments. The accompanying increase in studies of avian populations has resulted in a growing need for a comprehensive bibliography...
