G.R. Hess, W. R. Normark
1976, Marine Geology (22) 233-251
There are three major fan valleys on upper Monterey fan. Deep-tow geophysical profiles and 40 sediment cores provide the basis for evaluation of the sedimentation histories of these valleys. Monterey fan valley leads from Monterey canyon to a major suprafan and is bounded by levees that crest more than 400...

Preliminary residual magnetic map of the eastern Bering Shelf and parts of western Alaska
Kimberly A. Bailey, Alan K. Cooper, Michael S. Marlow, David W. Scholl
1976, Miscellaneous Field Studies Map 716
Residual magnetic anomalies for the offshore data were calculated by subtracting the Earth's main dipole field, adjusted for secular variations (based on the International Geomagnetic Reference Field (IGRF), epoch 1965, Fabiano and Peddie, 1969), from the observed values of the surveys listed below. The effects of diurnal variations and magnetic...

The Lisburne Group: A potential major hydrocarbon objective of the Arctic Slope, Alaska
Kenneth J. Bird, Clifton F. Jordan
1976, Open-File Report 76-786
The Lisburne Group, a thick carbonate rock unit of Mississippian and Pennsylvanian age, is one of the most widespread potential reservoir rock units in northern Alaska. A comprehensive review of the Lisburne in the subsurface of the eastern Arctic Slope indicates attractive reservoir characteristics in a favorable source and migration...
Sediment characteristics of streams in the eastern Piedmont and western Coastal Plain regions of North Carolina
Clyde E. Simmons
1976, Water Supply Paper 1798-O
The sediment-transport characteristics of streams were determined in a 15,500-square-kilometre (6,000-square-mile) area of the Coastal Plain and Piedmont regions of eastern North Carolina during 1969-73. The study covered all or parts of 21 counties and included data for 28 sediment-sampling stations in parts of 4 major river basins?the Roanoke, Pamlico,...
