Multichannel seismic profiles collected by the Teledyne Exploration Company in 1977 south of Cape Hatteras, North Carolina Multichannel seismic profiles collected by the Teledyne Exploration Company in 1977 south of Cape Hatteras, North Carolina

The U.S. Geological Survey (U.S.G.S.) collected approximately 3,700 km of multichannel-seismic reflection profiles (lines TD-1 – TD-6) south of Cape Hatteras on the continental margin. Those profiles were collected between August 15 and October 30, 1977, under U.S.G.S. contract number 14-08-0001-16209 by the Teledyne Exploration Company. The released data include copies of the original...

Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1981 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1981

The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

210Pb method for estimating the rate of carbonate sand sedimentation 210Pb method for estimating the rate of carbonate sand sedimentation

The plot of 210Pb activity against depth in carbonate sands on the Virgin Island Bank is a negative asymmetric hyperbolic curve. As depth increases, an initial rapid decrease in 210Pb activity caused by the decay of unsupported 210Pb and 226Ra is followed by increasing activity as a result of 210Pb achieving equilibrium with in growing 230Th. As this curve is time dependent, an estimate...

Mid-range sidescan-sonar images covering parts of proposed tracts for OCS lease sale 56 and contiguous areas, Manteo, Cape Fear, and adjacent quadrangles off North Carolina Mid-range sidescan-sonar images covering parts of proposed tracts for OCS lease sale 56 and contiguous areas, Manteo, Cape Fear, and adjacent quadrangles off North Carolina

The U.S. Geological Survey (USGS), in cooperation with the U.S. Bureau of Land Management (BLM) and the Lamont-Doherty Geological Observatory (LDGO), collected 335 km of mid-range sidescan-sonar data in some of the tracts proposed for inclusion in Federal OCS (Outer Continental Shelf) Oil and Gas Lease Sale 56 and in some contiguous areas (R.V. GYRE, September 18-25, 1980 [GYRE 80-9, leg...

Sedimentary framework of the Potomac River estuary, Maryland Sedimentary framework of the Potomac River estuary, Maryland

Analyses of seismic-reflection profiles, sediment cores, grab samples, and side-scan sonar records, along with previously collected borehole data, reveal the characteristics, distribution, and geologic history of the shallow strata beneath the Potomac River estuary. The lowermost strata are sediments of the Chesapeake Group (lower Miocene to lower Pleistocene) that crop out on land near...

Single-channel seismic-reflection profiles and sidescan-sonar records collected by the R/V Neecho, cruise NE 79-06, on the inner shelf east of Cape Cod, Massachusetts Single-channel seismic-reflection profiles and sidescan-sonar records collected by the R/V Neecho, cruise NE 79-06, on the inner shelf east of Cape Cod, Massachusetts

Cruise NE 79-06 of the R/V NEECHO was conducted by the U.S. Geological Survey during September 27-0ctober 3, 1979, in the nearshore zone (3-30 m water depth) seaward of Coast Guard Beach and the northern part of Orleans Beach, east of Cape Cod, Massachusetts. The purpose of the study was to map the types and extent of nearshore bed forms and to define the late Pleistocene and Holocene...

Small landslide types and controls in glacial deposits: Lower Skagit river drainage, northern cascade range, Washington Small landslide types and controls in glacial deposits: Lower Skagit river drainage, northern cascade range, Washington

Observations of 167 small, shallow landslides spanning a 22-year period on extensively logged slopes of Quaternary terraces in the lower Skagit and Baker Valleys, Washington, shows that there is a relationship between the common slope failures in this area and the slope angle, stratigraphy, and logging practices. Landslide frequency increases upvalley, as do mean annual precipitation and...
