Growth faulting and salt diapirism; their relationship and control in the Carolina Trough, eastern North America
The Carolina Trough is a long, linear, continental margin basin off eastern North America. Salt domes along the trough's seaward side show evidence of active diapirism and a normal growth fault along its landward side has been continually active at least since the end of the Jurassic. This steep fault extends to a strong reflection event at about 11 km depth that may represent the top of a salt la

Hormonal treatment and flight feather molt in immature Sandhill Cranes
Molt, the production of a new generation of feathers, is a poorly understood physiological phenomenon in nondomestic birds. Often in large birds like geese, flight is restricted by clipping the primary remiges on 1 wing and flight is restored after the molt when the primaries are replaced. A similar technique would be desirable for use with cranes conditioned for release to the native habitat. How

Hydrates of natural gas in continental margins
Natural gas hydrates in continental margin sediment can be inferred from the widespread occurrence of an anomalous seismic reflector which coincides with the predicted transition boundary at the base of the gas hydrate zone. Direct evidence of gas hydrates is provided by visual observations of sediments from the landward wall of the Mid-America Trench off Mexico and Guatemala, from the Blake Outer

Intraslope basins in Northwest Gulf of Mexico; a key to ancient submarine canyons and fans
The hummocky, diapirically deformed Texas-Louisiana continental slope includes three major types of intraslope basins: blocked-canyon intraslope basin, interdomal basin, and collapse basin. Major sand bodies present in the blocked-canyon intraslope basins are used to determine the sedimentary history of the Tertiary and Quaternary of this area. During relative lowering of sea level, coarse silt an

Modern pesticides and bobwhite populations
Bobwhite (Colinus virginianus) are frequently used as test animals for wildlife tests of pesticides. The organophosphate and carbamate pesticides that have replaced the organochlorines have many desirable properties, but they span a wide range of acute toxicities and some of them affe,ct survival, reproduction, food consumption, behavior, and nervous system enzymes in laboratory tests.
