Published: October 2011

I have just returned from another meeting where a bewildering series of ten‐minute papers was presented and audience attendance decayed with a one‐day half life. Many of these papers were very worthwhile, but complicated material on too many slides made most of them incomprehensible. Anyone who wanted to understand a presentation sought out the author for private conversation. At large national meetings there are so many contributed papers that several sessions must run concurrently with frequently overlapping interest. Then it becomes physically impossible to cover some papers of interest. Furthermore most contributed papers are not ready for publication or in preprint form so it is impossible to obtain the results of these papers for several months.
Balloon flight
Authors: Anonymous
Published: October 2011

A globe‐circling balloon, launched September 29, 1967, at Christchurch, New Zealand, by researchers from NCAR, Boulder, Colorado, has broken all previous balloon flight‐duration records by remaining aloft for one year. The Global Horizontal Sounding Technique balloon circumnavigated the Southern Hemisphere more than 25 times, floating at a constant pressure‐level of 100 mbs, or about 52,000 feet. Made of mylar plastic and inflated with helium, the light and fragile balloon carried a five‐ounce electronics package which transmitted a radio signal for tracking purposes. The flight's duration helps demonstrate the feasibility of an operational GHOST system of 5,000 to 10,000 balloons circling the earth at predetermined atmospheric levels to collect weather data from most of the earth's atmosphere. Currently, adequate observations are available from only about 15% of the earth.

Changes in federal administration always bring with them questions of policy shifts affecting the sciences. Scientists have become deeply involved in such policies. They have energetically voiced opinions. The elders in the scientific establishment have almost unanimously advocated expansion in the various disciplines. The geophysical sciences have been no exception. A recent voice in this chorus has been the Commission on Marine Science, Engineering, and Resources. Most of the geophysical work in this country will receive considerable impetus if their recommendations are followed. We hope the new administration will move with foresight.
International geophysics: Geophysical interests of IUGS
Authors: Thurston William
Published: October 2011

The International Union of Geological Sciences (IUGS) was born in 1961, an offspring of the International Geological Congress (IGC) founded in 1878. IUGS was immediately accepted into the International Council of Scientific Unions (ICSU) and promptly became a working partner in a number of inter‐union and ICSU activities. It thereby achieved one of the goals that proponents of forming a union had hoped for: a plainly visible international organization through which scientists in many disciplines could communicate and collaborate with geological scientists.

IGC had formed many international commissions and committees in the years between 1878 and 1960, but these were left pretty much to their own devices in financing and conducting their work. They were expected to justify their existence by the results they could present for the approval of the Congress, generally at four‐year intervals, but there was no permanent channel through which they could be reached. It was difficult for many non‐geologists to discover the IGC group with which they shared a common interest. The IGC commissions in existence in 1960 were all transferred to IUGS by 1968, except for two which became international associations affiliated with IUGS; the Union has also established some commissions and committees of its own since 1961. Those of importance to geophysicists are given below.

Published: October 2011

Recently a project that was initiated and managed by the Columbus Laboratories of Battelle Memorial Institute positioned a geodetic marker on the Pacific Ocean floor 130 miles southwest of Los Angeles. It may well be the first step in the development of a practical means for precisely establishing locations in the ocean. The placing of the marker is the culmination of an experiment being conducted by several organizations that include Aerojet‐General Corporation, Bendix Electrodynamics Division, and Seismograph Service Corporation's SEISCOR Division. Creating the marine geodetic control point required a joint effort of sea, air, and land research teams.

JGR standards
Authors: Roederer Juan G.
Published: October 2011

JGR undoubtedly is one of the journals of highest standing in the geophysical sciences, and many papers originally rejected by JGR appear in other journals that impose less strict rules. This is a healthy situation for JGR, but on the other hand, it imposes a great responsibility on the Editors. By setting and maintaining high standards of the quality and type of research published in the Journal, they indirectly exert a control over the quality and type of research done in the field of geophysical sciences; this influence may be considerably greater than is generally realized.

The great variety of topics covered in JGR presents a serious difficulty: each one of the Co‐Editors cannot have a complete overlook on the whole field covered in his section. This implies that a well balanced group of Associate Editors is needed. Furthermore, it requires that Associate Editors bear a considerable responsibility in carrying out the editorial job, and that they maintain a close working relationship with the corresponding Co‐Editor. To give Co‐Editors and Associate Editors more freedom of action, they should not be allowed to publish in the Journal during their terms of office.
Tectonics of the San Andreas Fault System seismological studies
Authors: Eaton J. P.
Published: October 2011

The primary objectives of the current seismological program of the National Center for Earthquake Research (NCER) include: (1) evaluation of the use of well recorded aftershock sequences to delineate the slip surfaces associated with large earthquakes, (2) determination of the degree to which microearthquakes are confined to (and therefore delineate) the major faults that traverse the region of central California between the Gabilan range and San Francisco Bay, and (3) investigation of the space‐time‐energy relationships among microearthquakes and of the relation of crustal strain changes to the earthquake regime in central California.

Thirty‐two short‐period vertical seismometers are installed in four clusters in key localities along the San Andreas and associated faults in central California. Telemetered signals from these seismometers are recorded in compact format on three Develocorders at the NCER office building in Menlo Park, where reading and analysis of the seismograms are kept current. Hypocenters are determined by computer, using crustal models based on local refraction surveys and station corrections based partly on teleseism P‐wave delays and partly on average residuals for a large number of local earthquakes. Computer cards that summarize the principal parameters of each earthquake are collected in a card library to facilitate analysis of the earthquakes and the study of their relation to measured changes in crustal strain.
Rupture mechanics on the Hayward Fault
Authors: Bolt Bruce A. , Eisenberg A.
Published: October 2011

The Hayward fault is a right‐lateral, strikeslip fracture in the crust to the east of San Francisco Bay. Its earthquake history shows activity for the last 130 years; in 1836 and 1868, large damaging earthquakes were accompanied by surface rupture along the fault. At Berkeley, an intensive special study of the mechanics of the fault is possible. A mining adit exposes the gouge clay of the shear zone. Differential displacement of a culvert across the fault, measured continuously since 1965, shows a slippage rate of 2.5 mm per year over all with a definite pattern of seasonal fluctuations. The monitoring of small local earthquakes shows an average of 3 to 5 per year (2<M<3) within 10 km of Berkeley; focal depths are quite shallow with a few as great as 10 km.

Fault creep, earthquakes, and strain release in California
Authors: Smith Stewart W.
Published: October 2011

Recent data from the San Andreas fault show that episodes of rapid creep may either precede or follow the occurrence of local earthquakes. Both fault creep and earthquakes are processes that act to relieve tectonic stress. The factors that determine which process will be effective at a particular time and place depend in detail on the properties of the fault surface. These properties may include the coefficient of friction, the geometry, and the fluid pore pressure. Examples of both types of stress release can be seen on the San Andreas fault.
Geodetic work in Japan with special reference to the Matsuchiro earthquakes
Authors: Harada Yoshimichi
Published: October 2011

Geodetic surveys, first‐order leveling, triangulation with electro distance measurements, and geomagnetic and gravity surveys have been conducted by the Geographical Survey Institute in and around the area of the Matsushiro earthquake swarm in the northern part of Central Japan during the period from 1965 to 1968. During this period leveling surveys were resurveyed every three months in the vicinity of Matsushiro and the other surveys were made at approximately six‐month intervals. From the results of the surveys, the following facts have been found.

Extraordinary vertical deformations have continued near Mt. Minakami, with upheaval from October 1965 to September 1966 through the first and second peaks of seismic activities, followed by a subsidence. The maximum rate of the upheaval motion was about 50 mm per month. On the other hand, in the Omachi‐Matsukawa region, which is about 30 km from the central area of the earthquake swarms, anomalous reversals of the pattern in the vertical deformation have occurred, for which the period also seems to be about six months. The mean rate of up and down motion was about 40 mm per six months. Such a reversible vertical deformation was also found in the large region along the first‐order leveling routes through Nagano, Ueda, Matsumoto, and Omachi during the whole period of about three years, 1965–1968.
Studies of Matsushiro earthquakes: 3. Mobile observations on ultramicroearthquakes
Authors: Miki H. , Wantanabe H. , Nakamura M. , Kuroiso A. , Kimura S. , Kishimoto Y. , Hashizume M. , Mino K. , Matsuo S.
Published: October 2011

In studying the seismicity or the seismic activity of a certain region, the hypocentral distribution and its variation with time may have to be deduced from the results of observation on a routine basis or from a temporary observation network. In many cases, however, these observation systems cannot always be set for the sudden unexpected outbreak of an earthquake, because of insufficient funds or a lack of operators. Instead of the hypocentral distribution of individual earthquakes, the frequency distribution of S‐P duration times at a single station is therefore adopted for a rough determination of the seismic region as a whole. In accordance with these analytical methods, three mobile observations were made at several stations in the vicinity of Matsushiro to effectively investigate the seismic active region or its variation with time.
Studies of aftershocks and earthquake swarms in the Nevada region
Authors: Ryall Alan
Published: October 2011

Because of its high seismicity and generally low level of microseismic noise, the Nevada area has in recent years begun to play an important role in studies connected with the occurrence of microearthquakes and small earthquakes. During the last two years, a considerable effort by the Mackay School of Mines Seismological Laboratory has gone into field investigations of small earthquakes and development of analysis techniques for the handling of field recordings.

Techniques for analyzing microearthquake data have evolved primarily as a function of the conditions under which the data were collected. For the most part, these techniques represent attempts to make the maximum possible use of data collected at a small number of nearby recording locations. As a rule, field experiments have been carried out using a tripartite array 1 or 1 km in radius, supplemented by recordings on one or two single‐component systems. In recent studies, the supplementary recorders were operated for only a short time, and were used primarily to derive site corrections to arrival times of seismic waves at elements of the tripartite array. These corrections, designed to eliminate, insofar as possible without a detailed explosion study of the area, the effects of near‐surface structure on arrival times, permit the determinations of focal coordinates of nearby earthquakes using only P‐wave arrival times, S‐P times, and the geometrical properties of the array.
Recent progress on a magnetometer array on the San Andreas Fault
Authors: Kovach Robert L. , Breiner Sheldon
Published: October 2011

Four highly sensitive optically pumped rubidium vapor magnetometers are in continuous operation along the San Andreas fault near Hollister, California, to detect any local changes in the geomagnetic field, which are associated with earthquakes or creep displacement on the fault. The magnetometer signals are telemetered to a central reference station, and differences are formed in real time to reduce the effect of unwanted micropulsations. A telemetering creep recorder complements the magnetometer array. Local geomagnetic events have indeed been observed, occurring some tens of hours before the onset of local creep displacement. Two types of magnetic signatures are observed.
Detectability of seismomagnetic effect
Authors: Rikitake T.
Published: October 2011

Recent measurement of seismomagnetic effect by modern magnetometers indicates that very accurate observations should be made to detect a geomagnetic change possibly associated with an earthquake. Even if we use a proton precession magnetometer, which is free from a drift, attention should be drawn to the magnetic field produced by electric currents induced in the earth. Observations in Japan show that instantaneous values of the total geomagnetic field are considerably different for stations only several kilometers distant from one another.

It is also made clear that the total intensity values at a station are systematically larger or smaller in some cases than those values at another station. The fact suggests possible use of a weighted difference technique based on a proportional constant to be determined empirically. A standard deviation, amounting to 2γ, for comparison of instantaneous total intensity values between two stations 100–200 km distant from one another in Japan has been achieved by making use of the weighted difference technique for nighttime data.
Laboratory study of elastic shocks prior to rock failure
Authors: Mogi Kiyoo
Published: October 2011

In our previous works, the process of the occurrence of elastic shocks caused by microfracturing prior to rock failure was studied experimentally. These works provided an important suggestion for physical understanding of foreshock phenomena of earthquakes. In these previous studies, however, the number and the energy of elastic shocks originating from the whole sample, without any consideration of source locations, have been discussed. In the present paper, source locations of elastic shocks were determined in various rocks subjected to various stress systems by a new experimental technique.
Recent studies by the coast and geodetic survey

The results of approximately eight years of concentrated work are published in Bulletin 116‐6, ‘Geodimeter fault movement investigations in California.’ I recommend that everyone who is interested in this problem obtain a copy of this report and use it for reference.
Spectral analysis of P‐waves at short range as an indicator of focal parameters
Authors: Kisslinger Carl
Published: October 2011

The approach to understanding the physics of an earthquake is still largely empirical. Representations of the focal mechanism by a system of forces acting at a point, by a moving point source, and by distributions of elastic dislocations have contributed to an interpretation of the distribution in space and time of the displacements produced by an earthquake. When combined with laboratory evidence of the failure of materials, these representations, or perhaps others not yet conceived, may lead to a coherent theory of the earthquake source.

The applicability of analysis of the properties of seismic body waves in either the time or frequency domains in elucidating the characteristic of the source has been demonstrated by a number of investigators. In these investigations, the displacement or strain field at large distances has been the primary object of inquiry. Recently, some opportunities to observe in detail the behavior close‐in to the source have arisen, for example, in the Parkfield earthquake, and important new insights have been gained.

Pelagic tidal measurements: A suggested procedure for analysis
Authors: Cartwright David , Munk Walter , Zetler Bernard
Published: October 2011

There has long existed a need for pelagic tide and current measurements, but the technology for making such observations has been developed only recently. In 1965, an international working group on deep‐sea tides was formed (now sponsored by IAPSO, SCOR, and Unesco) that would concern itself with the exchange of information on instrumentation and analysis and with the formulation of a worldwide data acquisition program.

Some pelagic tide observations have now been obtained by pressure sensors on the sea bottom connected by cable to the surface [Eyri`es, 1968] or to shore [Nowroozi et al., 1968] and by self‐contained bottom instruments that record internally and are recalled to the surface by an acoustic signal [Snodgrass, 1968] and time‐release device [Filloux, 1968, and Hicks et al., 1965]. The equipment described by Snodgrass and by Nowroozi include current meters measuring speed and direction. The over‐all objectives of the deep‐sea tide program are described by Munk and Zetler [1967] and Cartwright [1969].

During the past few years more and more museums endeavoring to establish displays of representative articles involved in disciplines not previously a part of the museum are finding that many institutions and corporations have already disposed of their obsolete material. This is particularly true in many phases of geophysics. Accordingly, AGU has decided to do something about the situation.

A basic premise has been the establishing of a geophysical hall, hopefully at the Smithsonian Institution, and in the not too distant future. In keeping with current trends, the various displays will contain not merely a large amount of rejuvenated junk, but will attempt to convey the story of the development of theory, equipment, and technology. Instruments and displays will be carefully selected and designed to produce an even flow of information.
The role of basic research in universities
Authors: Dessler A. J.
Published: October 2011

At a time when government and society are reassessing national priorities, and support for basic research is uncertain, a clear definition of the role of basic research in universities is of vital concern. It is therefore appropriate that we examine university goals and the contribution of basic research toward attaining those goals. Arguments are put forth below to the effect that education is the only proper endeavor for a university, and the prime role for research in a university is as the principal tool for graduate education. It is the education of men and women, who through research learn to think creatively and imaginatively, that justifies a significant university involvement in basic research.

Geophysics as a formal discipline is represented at only a limited number of colleges and universities. Even our various subdivisions have relatively narrow representation on the faculties. This is not too surprising, because of the reluctance of university administrations to give formal recognition to interdisciplinary programs. In many schools the solid‐earth geophysicists are attached to geology departments, geodesists and hydrologists are associated with civil engineering groups, and aeronomists and planetologists live in symbiosis with the physicists.
Symposium on gravity surveys in western North America

Published: October 2011

Gravity surveys involve one of the most routine and frequently used types of geophysical measurements; they are made with a steadily improving precision that now exceeds 1 part in 100,000,000 and probably rank among the most sensitive of routine scientific techniques. The surveys have a wide variety of industrial, military, and research applications and are now made by commercial companies, government agencies, universities, and research institutions, each of which has different objectives and operating procedures. The results of some surveys have commercial and military objectives. Consequently, the data remain confidential and unpublished for many years; the objectives of other groups require complicated analyses that also tend to delay publication.

Authors: Nilsen T. H.
Published: October 2011

The Gravity Division of the Department of Geodesy of the Army Topographic Command (TOPOCOM) (formerly Army Map Service) in Washington, D.C., has been involved in various types of gravity survey operations in the western United States since 1965. The Division, with a staff of approximately twenty‐five, undertakes the following activities: (1) land gravity surveys; (2) coastal and lake bottom gravity surveys; (3) a limited amount of research and development, including new techniques for gravity measurement such as a helicopter gravity measuring system, earth‐tide studies, and improvements in surveying procedures and technology; (4) calibration and maintenance of a large number of LaCoste‐Romberg gravimeters at a laboratory near Herndon, Virginia; (5) development and implementation of procedures and programs for computer reduction of various types of gravity data for geodetic purposes; and (6) financial and administrative monitoring of contracts for procurement of gravity data involving TOPOCOM and various university and government agencies throughout the world.

The Department of Defense requires gravity data for various geodetic and mapping purposes. Required gravity coverage for selected land and shallow‐water areas is obtained through (1) field surveys by TOPOCOM personnel, (2) contracts with university, state, or federal groups either engaged in or interested in gravity surveying operations in the selected areas, or (3) cooperative programs involving personnel from TOPOCOM and other agencies or universities. In western North America, TOPOCOM has engaged in gravity survey operations on a contract or cooperative basis with the following groups: (1) the Universities of Washington, Puget Sound, Montana, Oregon, Utah, Arizona, Stanford, California at Santa Barbara, California at San Diego, Hawaii, and MIT; (2) U.S. Geological Survey; (3) California Division of Mines and Geology; (4) the Dominion Observatory in Ottawa, Ontario, Canada.
Summary of 1st geodetic survey squadron gravity activities in western United States 1963‐1968

Most of the gravity surveys of the U.S. Geological Survey have been support programs in connection with regional geologic structural studies, ground‐water investigations, and heavy‐metals exploration. Many of the studies were undertaken in conjunction with geological mapping and mineral investigations by the Survey's project geologists. Gravity data often complement aeromagnetic surveys to identify the sources of potential‐field anomalies; other gravity data have been used to supplement high‐resolution seismic and electrical investigations [Mattick, 1967]. Geochemical follow‐up has been fruitful in western Montana [ Mudge et al, 1967].
Regional gravity studies of western and central Montana
Authors: Smith Robert B.
Published: October 2011

During the summer and fall of 1963 a U.S. Air Force geodetic survey team of the 1381st (now the 1st) Geodetic Survey Squadron, under the supervision and direction of the author, conducted a regional gravity survey in western and central Montana. This survey established 2700 gravity stations and an associated base station network in the general area outlined from 106°W to 115°W and from 45°N to 49°N. The principal objectives of this work were to determine the feasibility of using combined geodetic and gravity data to evaluate gravimetric interpolation of astro‐geodetic deflections of the vertical and to determine the accuracy of astronomical positions corrected for gravimetrically interpolated astro‐geodetic deflections of the vertical [Anthony, 1964]. The data were later released to the author for geological interpretation.
Gravity surveys in Utah
Authors: Cook Kenneth L.
Published: October 2011

Since 1955 the University of Utah has made gravity surveys throughout Utah in a continuing program to compile a gravity map of the entire state. The field work, compilation, and interpretation of data have been done chiefly by Geophysics graduate students and faculty with financial support provided by various federal, state, and private agencies.

The present paper summarizes the progress and results of these surveys since the last similar summary [Cook, 1965]. The earlier paper gave the objectives and results of the gravity surveys over many of the rift valleys in northern Utah.
The U.S. Geological Survey's gravity program in California
Authors: Oliver Howard W.
Published: October 2011

Since the 1963 gravity symposium, the U.S. Geological Survey has entered into a cooperative program with the California Division of Mines and Geology, the Army Map Service, and several universities for the purpose of completing a 5‐mgal Bouguer gravity map of the entire State of California at a scale of 1:250,000 by 1970. The areal division of responsibility within the program is shown on a map of California by Chapman (p. 542).

It is evident from a plot of existing stations that considerably more data are required in the eastern Mojave Desert located in the southeastern corner of the state, and in the Sierra Nevada north of Lake Tahoe. Additional fill‐in work is needed in nearly all parts of the state. The data requirements vary for a 5‐mgal contour map depending on the local complexity of the gravity field; but in general, we are obtaining gravity stations at an interval of about 3 km along roads, trails, and rivers, and 5 to 8 km between these access routes by cross‐country jeep, horseback, or helicopter if necessary. About 6000 new stations were obtained in California by the Geological Survey during 1968 and we expect to obtain about 3000 more in 1969.
Gravity surveys in the Western Transverse Range Province, Calfornia
Authors: Rietman Jan D.
Published: October 2011

The Transverse Range Province of California contains the major east‐west trending structural features of southern California. It extends from the coast where the Santa Ynez Mountains plunge into the Pacific Ocean eastward to within fifty miles of the Colorado River. This paper briefly summarizes recent gravity work in that portion of the province west of longitude 118°30′

For the past fifty years this province has been a major region of oil and gas exploration, and production and much geophysical and geological effort has gone into unraveling its stratigraphic and structural complexities. Within the past few years the petroleum industry has conducted numerous offshore geophysical surveys, including detailed gravity work, in preparation for drilling on the federal leases that were opened in the Santa Barbara Channel in 1968.
Gravity results in western Washington
Authors: Daneš Zdenko F.
Published: October 2011

Gravity surveys in western Washington have been conducted by this author and University of Puget Sound students since 1962, and about 5000 gravity measurements have been made. Two instruments have been used: Worden meter 358, owned by the University, and a LaCoste‐Romberg G‐68 loaned by the Army Map Service, which has also financed the survey during the past four years.

Simple Bouguer corrections are applied to all stations; terrain corrections have been calculated for selected points and soon will be derived for all stations by a computer program written by R. Krimmel. Most stations are located where elevations have been determined by other agencies (USGS, USCGS, Corps of Engineers, railroad and power companies, highway construction crews, etc.), and some level lines have been run by our own group. In other cases, barometric elevations were used, but their reliability is poor. The survey datum is based on Woollard's [1958] network, and is tied into previous or contemporary work by Bonini (p. 531), Stuart [1961, 1965], Jones, [1952], Christensen et al. (p. 548) and Walcott [1967].
Forest Service studies in evapotranspiration
Authors: Anonymous
Published: October 2011

Studies of evaporation and transpiration are being conducted by Forest Service personnel at several locations in the United States. Methods of study include measuring the response in streamflow to vegetation manipulation on carefully calibrated watersheds, determining radiation and soil moisture indices of evapotranspiration, measuring the amount of water intercepted and evaporated from vegetation, measuring the energy potentials of water in plants, and testing the effectiveness of evaporation retardants. This report includes a sample of recent study results, and it describes a few studies that were recently begun.

Water yield has increased substantially on two small watersheds in Central Arizona following control of chaparral brush and conversion to grass. Annual streamflow increases on the treated watersheds have varied from 1.5 to 14.0 inches during the past seven years; the amount of yield increase was correlated with winter precipitation amounts. When annual precipitation was less than 16 inches, the increase for that year was usually less than 2 inches. At 34 inches of annual precipitation, the increase in flow may reach 12 inches or more, depending on seasonal rainfall distribution.
Disposition of agricultural pesticide studied
Authors: Anonymous
Published: October 2011

A working group of Agricultural Research Service scientists are studying the fate of two chlorinated hydrocarbon pesticides (Dieldrin and Heptachlor) applied in the surface of a small watershed at the North Appalachian Experimental Watershed near Coshocton, Ohio. Runoff and sediment transport are sampled as they occur and periodic measurements are being made of the material carried from the treated area in vapor form. Corn samples will be analyzed for Dieldrin and Heptachlor uptake, and soil samples will be examined to determine the amount of pesticide remaining in the soil at the end of each growing season. Evapotranspiration data from an adjacent weighing iysimeter and intensive micro‐climate sensing equipment are used in an evaluation of the air transport phase of a complete Dieldrin and Heptachlor budget.
