Feasibility and technology for making remote measurements of solutes in water
Marvin C. Goldberg, Eugene R. Weiner
1977, Journal of Research of the U.S. Geological Survey (5) 561-563
An indepth evaluation of the available technology in the field of laser-Raman spectroscopy indicates that a TV-type detector, a single monochromator with a holographic grating, an entrance slit filter blocking the Rayleigh light, and a pulsed laser coupled to signal averaging electronics is the best combination of commercial equipment that...
Simulation of flow from an aquifer to a partially penetrating trench
Stanley A. Leake
1977, Journal of Research of the U.S. Geological Survey (5) 535-540
Construction of the Tennessee-Tombigbee Waterway in northeast Mississippi will involve dewatering as much as 46 m of an unconfined aquifer near the Tennessee Valley divide. Dewatering by trenching is one of the proposed methods. Methods of calculating effects of dewatering by trenching have been heretofore limited to situations where ideal...
Periphyton and phytoplankton in the Sacramento River, California, May 1972 to April 1973
Linda J. Britton
1977, Journal of Research of the U.S. Geological Survey (5) 547-559
Periphyton and phytoplankton samples were collected monthly at five sites in the Sacramento River between May 1972 and April 1973. Periphyton were analyzed for species identification and biomass, and phytoplankton were analyzed for species identification and concentrations. The results were used to assess biological water-quality conditions in the river and...
A thermostatic water bath for experimental studies in aqueous solutions
R. M. Siebert, K.A. McGee, P. B. Hostetler
1977, Journal of Research of the U.S. Geological Survey (5) 597-602
A temperature-controlled water bath for the study of ion-pairing equilibria and mineral solubility in aqueous solutions below 100°C is described. The bath is similar to a previously described system (P. B. Hostetler and C. L. Christ, 1968, U.S. Geol. Survey Prof. Paper 600-D, p. D217-D221) but incorporates several significant improvements....
Chemical structure of humic acids - Part 2, the molecular aggregation of some humic acid fractions in N, N-dimethylformamide
R.L. Wershaw, D.J. Pinckney
1977, Journal of Research of the U.S. Geological Survey (5) 571-577
Humic acid fractions form molecular aggregates in solution. In previous studies we have shown by small angle X-ray scattering that the size of these aggregates is a function of pH. In this study we have found that the size of the aggregates of two humic acid fractions in water and...
A method for adjusting values of Manning's roughness coefficient for flooded urban areas
H. R. Hejl Jr.
1977, Journal of Research of the U.S. Geological Survey (5) 541-545
A method is presented for adjusting values of Manning's roughness coefficient for flooded urban areas on the basis of the density of buildings on a flood plain and verified roughness coefficients for natural conditions. An urban roughness coefficient can be calculated to emulate the water-surface profiles to within 0.06 meter...
Maps published of Antarctica by the U.S. Geological Survey
Water Resources Division, U.S. Geological Survey
1977, Report
The Geological Survey in cooperation with the National Science Foundation prepares and publishes topographic maps of selected areas of Antarctica needed to support the U.S. Antarctic Research Program (USARP) efforts. These maps are prepared from aerial photography flown by U.S. Navy Air Development Squadron Six (VXE-6) in accordance with USGS...
A Holocene vegetation record from the Mississippi River Valley, southeastern Missouri
J.E. King, W.H. Allen Jr.
1977, Quaternary Research (8) 307-323
Pollen preserved in a peat deposit from a large swamp, the Old Field in the Mississippi River Valley near Advance, Missouri, records radiocarbon-dated vegetation changes between 9000 and about 3000 years ago. The principal feature of both the percentage and influx pollen diagrams is the replacement of arboreal pollen, primarily Quercus,...
Radiocarbon dates and late-Quaternary stratigraphy from Mamontova Gora, unglaciated central Yakutia, Siberia, U.S.S.R.
T. L. Pewe, A. Journaux, R. Stuckenrath
1977, Quaternary Research (8) 51-63
A fine exposure of perennially frozen ice-rich silt and associated flora and vertebrate fauna of late-Quaternary age exists at Mamontova Gora along the Aldan River in central Yakutia, Siberia, U.S.S.R. The silt deposit caps a 50-m-high terrace and consists of three units. An upper layer 1–2 m thick overlies a...
Structure and sediment distribution in the western Bering Sea
P. D. Rabinowitz, A. Cooper
1977, Marine Geology (24) 309-320
Eleven seismic reflection profiles across Shirshov Ridge and the adjacent deep-water sedimentary basins (Komandorsky and Aleutian Basins) are presented to illustrate the sediment distribution in the western Bering Sea. A prominent seismic reflecting horizon, Reflector P (Middle—Late Miocene in age), is observed throughout both the Aleutian and Komandorsky Basins at...
The organic geochemistry of black sedimentary barite: Significance and implications of trapped fatty acids
R.E. Miller, D.A. Brobst, P.C. Beck
1977, Organic Geochemistry (1) 11-26
Fatty acids isolated in sedimentary black barite (BaSO4) from Arkansas and Nevada were identified by gas chromatography-mass spectroscopy. The dominant or major fatty acids found in these beds of barite are C16:0, C18:0, and C18:1. The occurrence and distribution of these acids in this type of rock may serve as...
Suspended particulate loads and transports in the nepheloid layer of the abyssal Atlantic Ocean
P.E. Biscaye, S.L. Eittreim
1977, Marine Geology (23) 155-172
Vertical profiles of light scattering from over 1000 L-DGO nephelometer stations in the Atlantic Ocean have been used to calculate mass concentrations of suspended particles based on a calibration from the western North American Basin. From these data are plotted the distributions of particulate concentrations at clear water and in...
Paleoenvironmental analysis and correlation of a Cretaceous Islas Orcadas core from the Falkland Plateau, Southwest Atlantic
P.F. Ciesielski, W.V. Sliter, F.H. Wind, S.W. Wise Jr.
1977, Marine Micropaleontology (2) 27-34
A comparison of Campanian-Maestrichtian cores from two localities on opposite sides of the Maurice Ewing Bank, at the eastern end of the east-west trending Falkland Plateau (Southwest Atlantic) reveals a significant change in faunal and floral assemblage characteristics across the Plateau. These changes are probably temperature dependent, and indicate that...
Verification of a model for predicting the effect of inconstant temperature on embryonic development of lake whitefish (Coregonus clupeaformis)
William H. Berlin, L.T. Brooke, Linda J. Stone
1977, Technical Paper 92
Eggs stripped from lake whitefish (Coregonus clupeaformis) spawning in Lake Michigan were incubated in the laboratory at temperatures similar to those on whitefish spawning grounds in Lake Michigan during December-April. Observed times from fertilization to attainment of each of 21 developmental stages were used to test a model that predicts...

Availability of ground water in Montgomery County, Maryland
Claire A. Richardson
1977, Open-File Report 76-882
Montgomery County, Md., is underlain by consolidated rocks that, on the basis of well yields, have been subdivided into six hydrogeologic units. The distribution of the hydrogeologic units are shown on a map (scale 1:62,500). Most wells drilled in the county yield between 6 and 25 gal/min (0.4 to 1.6...
