Thermogenic gases in near-surface sediments of Norton Sound, Alaska
C. Hans Nelson, Keith A. Kvenvolden, Edward C. Clukey
1978, Conference Paper
A plume of hydrocarbon gases, assumed to be of thermogenic origin based on chemical compositions, has been noted by others in the water column of Norton Sound about 40 km south of Nome, Alaska. We used detailed geophysical transects, side-scan sonar, underwater television, and chromatographic analyses of gases in near-surface...
Episodes of Aleutian Ridge explosive volcanism
J.R. Hein, D.W. Scholl, J. Miller
1978, Science (199) 137-141
Earlier workers have overlooked deep-sea bentonite beds when unraveling the Cenozoic volcanic history of an area. In the North Pacific, identification of Miocene and older volcanic episodes is possible only if both altered (bentonite) and unaltered ash beds are recognized. Our study, which includes bentonite beds, shows that volcanism on...

David William Scholl
1978, Open-File Report 78-422
The Geological Survey's marine geology investigations in the Pacific-Arctic area are presented in this report in the context of the underlying socio-economic problem of expanding the domestic production of oil and gas and other mineral and hard- and soft-rock resources while maintaining acceptable standards in the marine environment. The primary...

Sea otter predation and community organization in the western Aleutian Island, Alaska
J. E. Estes, N. S. Smith, J. F. Palmisano
1978, Ecology (59) 822-833
Predation by the sea otter (Enhydra lutris) limits epibenthic invertebrates, especially sea urchins (Strongylocentrotus polyacanthus), in turn allowing a luxuriant development of the macroalgal canopy. Where sea otters are abundant, sea urchins are small and scarce in shallow water, and the association of fleshy macroalgae apparently is regulated by competition....
