Geologic hazards in Navarin Basin Province, Northern Bering Sea Geologic hazards in Navarin Basin Province, Northern Bering Sea
Navarin Basin, scheduled for leasing in 1984 (OCS sale 83), may contain vast accumulations of oil and gas. Several geologic and oceanographic processes that may be active in and around Navarin Basin province could be hazardous to commercial development. These potential hazards include submarine slides; sea-floor instability resulting from disturbance of gas-charged sediment; sediment...

Hazard analysis on the Mid-Atlantic Continental Slope, DCS lease sale 59 Area Hazard analysis on the Mid-Atlantic Continental Slope, DCS lease sale 59 Area
A multi-parameter high-resolution seismic survey covering 253 offshore lease blocks was undertaken for analysis of critical structural and depositional features and a suite of piston cores was examined for geotechnical properties on the Mid-Atlantic continental slope in the OCS Lease Sale 59 area. The analysis of this data revealed complex interrelationships between a number of buried...

Net-mortality of Common Murres and Atlantic Puffins in Newfoundland, 1951-81 Net-mortality of Common Murres and Atlantic Puffins in Newfoundland, 1951-81
Band recoveries (N = 315) over 26 years (1951-77) and three surveys of seabird bycatch in inshore fishing nets (1972, 1980-81) indicate that there has been a substantial net-mortality of Atlantic Puffins (Fratercula arctica) and Common Murres (Uria aalge) in Newfoundland coastal waters for the past 2 decades. Offshore (e.g. Grand Banks) gill-netting is limited, but some data suggest that...

Paleoenvironment and age of kaolin deposits in the Andersonville district, Georgia Paleoenvironment and age of kaolin deposits in the Andersonville district, Georgia
The kaolin deposits of the Andersonville district of Georgia are thick and relatively pure; they grade laterally and vertically into sandy kaolin and sand. The sedimentological and mineralogical character of the clay and the enclosing sand suggests deposition in a marine shallow-water to estuarine environment. Palynomorph and invertebrate fossil assemblages from strata adjacent to the...

Recent trends in the west Greenland salmon fishery, and implications for Thick-billed Murres Recent trends in the west Greenland salmon fishery, and implications for Thick-billed Murres
In the late 1960s and early 1970s, a high net-mortality of seabirds, particularly Thick-billed Murres (Uria lomvia), was associated with the west Greenland salmon fishery. Since 1972, the domestic fishery has been controlled by quotas and fishery opening dates and non-Greenlandic offshore drift-net fishery was phased out in 1975. These restrictions probably resulted in a substantial...

Continuous subaqueous deposition of the Permian Castile evaporites, Delaware Basin, Texas and New Mexico Continuous subaqueous deposition of the Permian Castile evaporites, Delaware Basin, Texas and New Mexico
Structures that are common in the Castile Formation (Ochoan) of the Delaware Basin, Texas and New Mexico (Fig. 1) include fine planar laminations, breccias, microfolded laminae, and nodular anhydrite. These structures, particularly the laminae, have been used to demonstrate the subaqueous depositional history of the Castile (Anderson and Kirkland, 1966; Anderson et al., 1972; Dean et al...
