Available in PDF, EPUB and Kindle. Book excerpt: The tectonic history of the Arctic Ocean Basin, and in particular the Canada Basin and the adjoining Beaufort Sea shelf, today remains unclear even after decades of geological and geophysical investigations. Reconstruction of the tectonic history of the margin requires information about the deep crustal structure of northern Alaska at the Beaufort Sea. In 1975 and 1976 a substantial amount of refraction data was successfully collected on the Alaskan shelf from an icebreaker. This technical report contains a detailed description of the methods and techniques used in the data collection and analysis. Interpretation of the data is the subject of articles to be submitted to professional journals. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A marine seismic refraction study, conducted in August 1976 by personnel from Oregon State University and the University of Connecticut between Cape Simpson and Prudhoe Bay, Alaska, provides data for analysis which yields a subsurface structural and geological cross-section of the area. The results suggest that the structural homocline which dips to the east southeast on land extends to the offshore region as well. Correlation of geologic data from wells drilled on land with the refraction data permits tentative identification of geologic sequences on the basis of their seismic velocity. This study correlates 1.60 to 1.65 km/s layers to Quaternary sediments, 1.82 to 2.51 km/s layers to Tertiary strata, 2.91 to 3.40 km/s layers to Mesozoic formations to the east and 2.99 to 4.43 km/s to Early Mesozoic formations to the west. Velocities of 5.28 to 6.08 km/s are associated with probable argillite and phyllite of the Pre-Mississippian basement. At greater depths, refractors with velocities of 6.40 to 7.07 km/s are related to crystalline material which may be silicic or mafic. No seismic velocities typical of the upper mantle are present on the record sections, but a minimum depth calculation places the Mohorovicic discontinuity deeper than 20 km. Although the observed crustal velocities are ambiguous towards theories of the origin of the Canada Basin and the tectonic history of the northern Alaska margin, they tend to favor the orocline-Rift theory of Carey (1955) over a subduction margin.

Download or read book Travel Time Plots for Refraction Stations Near Kodiak Alaska written by George G Shor (Jr) and published by . This book was released on 1972 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: These travel-time plots and station notes are intended to serve as an appendix to the paper 'Marine Seismic Refraction Studies near Kodiak, Alaska'. A discussion of the results will be found in that paper and in a paper being prepared by von Huene on the structure of the Kodiak area. These station notes, of less general interest, are intended for those who wish to look at the plots on which the interpretations are made, and reinterpret for themselves if they desire. The original records are on file at the Marine Physical Laboratory of the Scripps Institution of Oceanography, La Jolla, California. All of the travel-time plots given are 'reduced plots' in which the travel-time has had subtracted from it the quantity(distance/7.0 km per sec). All stations except LF 19-20 were worked with water-delay time removed, and without topographic corrections to reduce the sea floor to a flat datum. Since the topography was quite smooth in most cases (as shown by the topographic plot at the bottom of each travel-time plot), topographic corrections to datum should not make any significant difference. The horizontal scale (distance in seconds) on each plot is the travel time of the direct water wave; the multiplier to convert it to kilometers is given as the water velocity in each case.
