摘要:
Equity Oil Company, as operator of the $9 million Equity/Department of Energy (DOE) in situ oil shale project, reported the commencement of project field tests involving superheated steam injections into oil shale‐bearing rocks of the Green River formation in northwestern Colorado.The project site, 35 miles southwest of Meeker, is at the geographic center of the Piceance Creek Basin, containing the world's largest single known deposit of oil shal

摘要:
In June 1977, the second largest U.S. meteorite was removed from the Old Woman Mountains of southeastern California by the Smithsonian Institution. A large amount of publicity accompanied the removal because of ownership claims by the prospectors who discovered the meteorite and because of demands by Californians that the meteorite be exhibited in California. The 10 largest U.S. meteorites discovered in or west of the Rocky Mountains are presently all exhibited in museums east of the Mississippi.The California congressional delegation became involved in presenting the case for retaining the meteorite in California, and finally, the Department of Interior announced that ‘with the concurrence of the Smithsonian Institution the Old Woman Meteorite would remain in California’ and ‘details of the maintenance and research arrangements would be worked out with the State of California.’ In this letter I want to discuss the Smithsonian's decision that about one‐third (1 ton) of the meteorite is required for scienti

摘要:
Five terrestrial techniques, i.e., sea level variations, repeated gravity surveys, tilt variations, repeated airborne terrain profiling, and repeated levelings appear to have sufficient accuracy to give useful information for detection of crustal movements of the order of a few centimeters. They are either being used already or have a clear potential of becoming useful, which cannot now be said of other available techniques, such as trigonometric heighting, barometric heighting, or photogrammetry.The techniques generally adopted for analyzing the complex ocean signal are numerical filtering and regression analysis. The aim of such an analysis is to eliminate those components of the signal which can be interpreted as caused by tides, barometric pressure changes, wind stress, steric topography, and other phenomena associated with marine dynamics, thus leaving the remaining variations, both secular and episodic, available for study. In spite of the limited understanding of ocean processes a certain measure of success has been achieved in this field, so that given good quality data, at least the secular trend can be identified. The work of the Permanent Service for Mean Sea Level in its current task of publishing mean sea level data in a new format should provide assistance in evaluating the eustatic contribution in the secular trend.
