Salt structure and sediment thickness, Texas-Louisiana continental slope, northwestern Gulf of Mexico
Raymond G. Martin Jr.
1973, Open-File Report 73-179
The objectives of this study were to determine the general configuration of the salt surface beneath the Texas-Louisiana continental slope and to isopach the Mesozoic-Cenozoic sedimentary section lying upon it. The structure contour map discloses that the entire slope province between the shelf edge and Sigsbee Escarpment is underlain by salt...
Erosional and Depositional Aspects of Hurricane Camille in Virginia, 1969
Garnett P. Williams, Harold P. Guy
1973, Professional Paper 804
Probably the worst natural disaster in central Virginia's recorded history was the flood resuiting from an 8-hour deluge of about 28 inches (710 mm) of rain on the night of August 19-20, 1969. This study examines some of the intensive sediment erosion and deposition that resulted from the storm and...
Regional gravity and magnetic surveys in the Albion Mountains area of southern Idaho
Don R. Mabey, Carol W. Wilson
1973, Open-File Report 73-165
Fault-bounded basins containing several thousand feet of sedimentary and volcanic rock of Cenozoic age are indicated by gravity lows in the Oakley area and in Upper-Raft River and Raft River Valleys. A gravity low and a magnetic high in the north end of Raft River Valley extends over the Cotterel...
Interstitial water studies on small core samples, Deep Sea Drilling Project: Leg 10
Frank T. Manheim, Fred L. Sayles, Lee S. Waterman
1973, Initial reports of the Deep Sea Drilling Project (10) 615-623
Leg 10 interstitial water analyses provide new indications of the distribution of rock salt beneath the floor of the Gulf of Mexico, both confirming areas previously indicated to be underlain by salt bodies and extending evidence of salt distribution to seismically featureless areas in the Sigsbee Knolls trend and Isthmian...
Effects of temperature on embryonic development of lake herring (Coregonus artedii)
Peter J. Colby, L.T. Brooke
1973, Journal of the Fisheries Research Board of Canada (30) 799-810
Embryonic development of lake herring (Coregonus artedii) was observed in the laboratory at 13 constant temperatures from 0.0 to 12.1 C and in Pickerel Lake (Washtenaw County, Michigan) at natural temperature regimes. Rate of development during incubation was based on progression of the embryos through 20 identifiable stages. An equation...
Thickness of the American woodcock eggshell, 1971
J.F. Kreitzer
1973, Bulletin of Environmental Contamination and Toxicology (9) 281-286
Eggs or empty shells of the American woodcockwere collected from 10 states in 1971and shell thickness (mean of clutch means) was compared with that of eggs collected from 16 states during the years 1859-1939. The 1971 shells (n = 91) from hatched eggs or those containing fully developed embryos were...
Sediment discharge in the Lake Tahoe basin, California, 1972 water year
Carl G. Kroll
1973, Report
Streamflow and fluvial-sediment discharge data are being collected at selected streams and highway gutters in the Lake Tahoe basin to determine the extent of erosion from highway cuts and to evaluate the effects of various land treatment practices to reduce erosion. Precipitation in the Lake Tahoe area during 1972 was 77...
Hydrologic Data of the Neponset and Weymouth River Basins, Massachusetts
R. A. Brackley, William B. Fleck, Richard E. Willey
1973, Massachusetts Hydrologic - Data Report 14
The Neponset, Weymouth Fore, and Weymouth Back River basins occupy an area of 183 square miles in eastern Massachusetts south of Boston and Braintree, Brockton, Canton, Dedham, Dover, Foxborough, Hingham, Holbrook, Medfield, Milton, Norwood, Quincy, Randolph, Rockland, Sharon, Stoughton, Walpole, Westwood, and Weymouth. Hydrologic data presented in this report were collected...
The benthic fauna of the Northern Bering Sea
Robert W. Rowland
1973, Report
The shelled benthic fauna of the northern Bering Sea has been extensively sampled and the taxonomy, distribution and functional role of 105 species of mollusks, two species of barnacles, two species of echinoids and one species of brachiopod havet4pen examined: The major benthic communities were evaluated by cluster analysis. They are: the Balanus rostratus alaskensis...
Interstitial water studies on small core samples, leg 19
F.L. Sayles, L.S. Waterman, Frank T. Manheim
1973, Initial reports of the Deep Sea Drilling Project (19) 871-874
The sediments cored on Leg 19 consist primarily of diatomaceous oozes with variable proportions of volcanic material and terrigenous clays and silts. With a few exceptions, deposition rates are high at these sites, usually exceeding 5cm/103y. The interstitial solutions sampled exhibit compositional changes which previously have been found to characterize...
Interstitial water studies on small core samples, legs 16, 17, and 18
L.S. Waterman, F.L. Sayles, Frank T. Manheim
1973, Initial reports of the Deep Sea Drilling Project (18) 1001-1012
Legs 16, 17, and 18 encountered three groups of sediment types: rapidly deposited biogenic deposits, showing marked changes in interstitial calcium, magnesium, and strontium; slowly deposited biogenic deposits, showing little variability in pore fluids other than elevated silica concentrations; and terrigenous deposits. The latter showed the usual loss of sulfate...
Mantle convection and volcanic periodicity in the pacific; Evidence from Hawaii
H. R. Shaw
1973, Geological Society of America Bulletin (84) 1505-1526
The thermal-feedback theory of mantle melting proposed by Shaw in 1969 is found to be quantitatively consistent with data pertaining to the evolution of the Hawaiian Ridge. Applicable rate factors are estimated from relations between lava volumes and position along the ridge given in this paper and the radio-metric age...
Crandall conglomerate, an unusual stream deposit, and its relation to heart mountain faulting
W. G. Pierce, W. H. Nelson
1973, Geological Society of America Bulletin (84) 2631-2644
The Crandall Conglomerate (Eocene) is a channel deposit, more than 350 ft (100 m) thick, believed to have formed as a result of preliminary movement of the Heart Mountain detachment fault in northwestern Wyoming. Initial movement of the Heart Mountain fault opened a deep rift in which the conglomerate was...
