Traveltimes and amplitudes from nuclear explosions; Nevada Test Site to Ordway, Colorado
Alan Ryall, David J. Stuart
1963, Crustal Studies Technical Letter 10
This paper treats the results of a study of seismic waves generated by eight nuclear explosions and recorded at 31 locations between the Nevada Test Site (NTS) and Ordway, Colorado. The line of recording stations crosses the eastern part of the Basin and Range Province, the Colorado Plateau, the southern...
Crustal structure in the western United States; study of seismic propagation paths and regional traveltimes in the California-Nevada region
J.C. Roller, W. H. Jackson, J.F. Cooper, B.A. Martina
1963, Crustal Studies Technical Letter 9
The U.S. Geological Survey, with the assistance of United ElectroDynamics, Inc., completed ten weeks of seismic-refraction field work during the summer of 1962 in the southwestern part of the United States. This work was a continuation of a program initiated in 1961 to study traveltimes and seismic propagation paths in...
Structure of the crust and upper mantle in the western United States
L. C. Pakiser
1963, Crustal Studies Technical Letter 8
Seismic waves generated by underground nuclear and chemical explosions have been recorded in a network of nearly 2,000 stations in the western conterminous United States as a part of the VELA UNIFORM program. The network extends from eastern Colorado to the California coastline and from central Idaho to the border...
Seismic-refraction measurements of crustal structure between Santa Monica Bay and Lake Mead
John C. Roller, John H. Healy
1963, Crustal Studies Technical Letter 7
A reversed seismic-refraction profile was recorded between Santa Monica Bay, California, and Lake Mead, Nevada, during November 1961. Depth to the Mohorovicic discontinuity was determined to be approximately 29 km at Santa Monica Bay, 36 km under the Transverse Ranges, 26 km under the Mojave Desert, and 30 km at...
Preliminary report on seismic-reflection studies of crustal structure in the western, central, and southern United States
J.C. Roller, O.P. Strozier, W. H. Jackson, J. H. Healy
1963, Crustal Studies Technical Letter 14
During 1963 the U.S. Geological Survey, with the assistance of United ElectroDynamics, Inc., recorded five separate reversed seismic profiles. In addition to these profiles, the U.S. Geological Survey participated in a seismic-calibration program for the DRIBBLE experiment at Tatum Dome, Mississippi, a 20,000-pound shot near Dexter, Missouri, and in a...
A progress report on seismic model studies
J. H. Healy, G. B. Mangan
1963, Crustal Studies Technical Letter 15
The value of seismic-model studies as an aid to understanding wave propagation in the Earth's crust was recognized by early investigators (Tatel and Tuve, 1955). Preliminary model results were very promising, but progress in model seismology has been restricted by two problems: (1) difficulties in the development of models with...
Surface water records of New Mexico, water year 1963
Water Resources Division, U.S. Geological Survey
1963, Water Data Report NM-63
The surface-water records for the 1963 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of New Mexico are given in this report. For convenience there are also included. records for a few pertinent gaging stations in bordering States. The records were collected and computed by...
Pre-nesting activity of the purple gallinule near Savannah, Georgia
Brooke Meanley
1963, The Auk (80) 545-547
Observations on the pre-nesting activity of the Purple Gallinule (Porphyrula martinica) were made by me at the Savannah National Wildlife Refuge, Jasper County, South Carolina from 9 to 16 April 1960, 12 to 23 April 1961, and 28 to 30 April 1963. Jasper County is in extreme southeastern South Carolina....
A survey of fungi associated with lesioned and chlorotic sago pondweed (Potamogeton pectinatus)
R.D. Lumsden, D.E. Ellis, J.L. Sincock
1963, Plant Disease Reporter (47) 689-693
Isolations from 1000 Potamogeton pectinatus plants collected from six major stands in Back Bay, Virginia and 13 in Currituck Sound, North Carolina yielded Pythium spp. consistently and in relatively high frequency. Although specific determination of these isolates was unsuccessful, they were separated into three groups according to morphological and cultural...
Nesting ecology and reproductive rate of the red-winged blackbird in tidal marshes of the upper Chesapeake Bay region
B. Meanley, J.S. Webb
1963, Chesapeake Science (4) 90-100
The nesting ecology and reproductive rate of the polygynous red-winged blackbird, Agelaius phoeniceus, were studied in the tidal marshes of Maryland during the period of 1958 through 1961. Sixteen nesting colonies were located in six major marsh communities of the Eastern Shore and were visited approximately twice a week from...
Quality of waters in California
Water Resources Division, U.S. Geological Survey
1963, Water Data Report CA-63-Water Quality
The quality-of-water investigations of the U.S. Geological Survey are concerned with the chemical and physical characteristics of surface and ground water supplies of the nation in conjunction with water usage and its availability. The basic records for the 1963 water year for quality of surface waters within the State of...
Water resources of the Virgin Islands, a preliminary appraisal, 1963
P.E. Ward, D.G. Jordan
1963, Open-File Report 64-158
Rainfall in the Virgin Islands averages about 44 inches per year, yet fresh water is in short supply, and the general impression of the islands is one of dryness. Land slopes are steep and runoff from rainstorms flows rapidly to the sea in the numerous, short, steep stream courses. During...
