Geomagnetic reversals and long‐period secular variation
Authors: Cox Allan , Opdyke Neil
Published: April 2012

A number of notable contributions to our knowledge of long‐period fluctuations of the geomagnetic field have been made since 1967 through studies of the paleomagnetism of igneous and sedimentary rocks. The highlights of this research include the following: (1) A more accurate radiometric time scale of geomagnetic reversals has been developed for the past 5 m.y., with the result that during this time all polarity intervals with durations longer than 50,000 years have probably been recognized. (2) An intensive study of deep‐sea sedimentary cores has served to define this time scale more accurately and to extend it back in time well beyond 5 m.y. (3) Marine magnetic anomalies have been analyzed by using the theory of sea‐floor spreading to yield a reversal time scale extending back 70 m.y. (4) Long‐period geomagnetic secular variation within individual polarity intervals has been investigated paleomagnetically by studying paleointensities and by measuring variations in angular dispersion of directions of the earth's field as a function of latitude. In the present report all these subjects are reviewed with the exception of marine magnetic anomalies, which are discussed in a separate report. In addition to the references cited specifically in the text, numerous important papers relevant to these subjects are listed in the bibliography.
The President' Page: A matter of perspective
Authors: Newell Homer E.
Published: April 2012

The President's budget for Fiscal Year 1972 calls for increases over Fiscal Year 1971 in total federal authorized obligations and estimated expenditures for research and development. Moreover, the budget requests increased support for research and development at colleges and universities. Coming after a period of anguished debate over an apparent national disenchantment with science and technology, the President's budget request is most heartening.
Research in physics at Aberdeen
Authors: Anonymous
Published: April 2012

Aberdeen University in Aberdeen, Scotland, attempts to make the most of the advantages it has in special competence and in geographical situation, while minimizing the disadvantages incurred from a peripheral position among British universities. They are weak in research student numbers but for individual research students this has the compensating advantage that he is likely to receive more careful supervision from senior staff than if he were working in a large team. Additionally, while heavy expenditure on large‐scale apparatus such as particle accelerators would be impracticable, the department is well equipped, notably in workshop and electronics services; and the university library is strong.

The main research effort is in pure physics but there is considerable emphasis also on geophysics and radio astronomy.
DSDP scientists discover how Panama Isthmus was formed
Authors: Anonymous
Published: April 2012

Recent findings by the Deep Sea Drilling Project explaining how the Isthmus of Panama was formed were announced at the AGU Annual Meeting in April by Tjeerd H. van Andel and G. Ross Heath of Oregon State University's Department of Oceanography as one of the principal results of Leg 16 of the Deep Sea Drilling Project. The cruise began in Cristobal, Panama, on February 5 and ended in Honolulu, Hawaii, on March 30.

During the first part of drilling vessel Glomar Challenger's sixteenth cruise, the shipboard scientists tested a hypothesis developed recently at Oregon State University and Lamont‐Doherty Geological Observatory of Columbia University. On the basis of geophysical observations, this hypothesis suggests that 10 to 15 million years ago an ocean ridge extended eastward from the present position of the Galapagos Islands. This ridge split lengthwise as a rift zone grew from the eastern end. The southern half remained at its position near the equator while the northern half broke in several pieces that began a slow drift northward in response to thermal currents deep in the earth.

Authors: Anonymous
Published: April 2012

A sophisticated airborne radar system that can ‘see’ at night and through clouds is being used by the Aero Service Division of Litton Industries to map and create photo‐like images of uncharted jungle regions of South America.

An aerial search for natural resources over 80,000 square miles of the cloud‐covered Orinoco basin in Venezuela using a Side‐Looking Airborne Radar (SLAR) system installed aboard a high‐altitude jetliner is being conducted by Litton Aero Service in association with Goodyear Aerospace Corp. Plans for a second SLAR survey will begin in May and cover 600,000 square miles of the Brazilian Amazon basin, an area onefifth the size of the United States. This project will be conducted in association with LASA, Brazil's leading civil engineering and resources firm. The two contracts amount to about $6.5 million.
New method aimed at detecting nickel
Authors: Anonymous
Published: April 2012

A new method that can be used to detect nickel and other elements in the earth's crust, and possibly on the ocean floor and on the surface of other planets, has been revealed by scientists of the U.S. Geological Survey.

USGS physicist and project leader Frank Senftle, reported results from USGS laboratory experiments in which radiation signals given off by nickel under neutron bombardment were quickly identified. Senftle and other USGS scientists are working with D. Duffey (University of Maryland) and P. Wiggins (U.S. Naval Academy). They are using an unconventional neutron activation technique ‘which appears to be more sensitive than ordinary neutron activation for some elements.’
Electrical logging system will help detect marine pollution
Authors: Anonymous
Published: April 2012

A new tool to help detect and control marine pollution has been developed by Texas A&M Sea Grant oceanographers. An electrical logging system that provides relatively quick and inexpensive measurements of upper soft sea‐bottom sediments has been successfully tested. Further development and adaptation to computer techniques is planned, with continued support by the National Sea Grant Program, a part of NOAA.

A key feature of the system is an in‐place gravity probe incorporating electrodes in the nose, which is dropped into the soft bottom sediments. In its present configuration, it measures the electrical resistances of the sediments as it is withdrawn.

Internal waves
Authors: Wunsch Carl
Published: April 2012

Progress in the United States in the study of oceanic internal waves has continued in both observational and theoretical areas. Whereas the theories are becoming more sophisticated all the time, their bearing on the observations remains peripheral and speculative. This state of affairs is primarily because of the lack of definitive field observations and the ambiguities that arise in almost all real data. Most work, theoretical and observational, falls into several broad, overlapping categories, which we will examine here.
Marine geophysics
Authors: Drake Charles L.
Published: April 2012

The period 1967–1970 was one of the most productive in the relatively short history of marine geophysics. A considerable body of data was collected that pertains to the properties, structure, and history of the oceanic areas. The concept variously termed sea floor spreading, new global tectonics, or plate tectonics was greatly strengthened through the addition of new data of many types from all the major ocean basins and the marginal seas. Many of these data would not strictly have been considered as derived from marine geophysical investigations in the past, but these data are geophysical and pertain to the marine areas, so they are included in this summary.
Ocean Sediment Coring Program
Authors: Peterson M. N. A.
Published: April 2012

The Ocean Sediment Coring Program is providing samples of sediments and a small amount of crystalline volcanic or igneous rock from far beneath the floor of the deep ocean basins. Drilling uses largely proven and conventional rotary drilling technology.

The program fulfills a real need of the times. Two hundred years ago, based on suitable navigational instruments, the era of Captain Cook mapped the oceans. One hundred years ago, the H.M.S. Challenger measured the depths of the ocean basins and established the broad contours of the bottom of the oceans. Today, the Ocean Sediment Coring Program is adding the next dimension of time to our knowledge of the ocean basins.
Soil moisture

Published: April 2012

Infiltration continues to occupy the attention of soil physicists and engineers. A theoretical and experimental analysis of the effect of surface sealing on infiltration by Edwards and Larson [1969] showed that raindrops reduced the infiltration rate by as much as 50% for a two‐hour period of infiltration. The effect of raindrops on the surface infiltration rate of soils has been investigated by Seginer and Morin [1970] who used an infiltration model based on the Horton equation. The effect of antecedent moisture on infiltration rate was shown by Powell and Beasley [1967] to be dependent on crop cover, degree of aggregation, and bulk density. The effect of snow cover and type of frost on the soil infiltration rate has been studied by Haupt [1967] on small plots in the Sierra Nevada Mountains in California. The steady infiltration from a shallow, circular, inundated area on the horizontal surface of a semi‐infinite porous medium is treated by a method of linearization by Wooding [1968].
Evaporation and transpiration
Authors: Ekern Paul C.
Published: April 2012

A more complete understanding of the evaporative processes and a fund of experimental data have spurred the development of numerical modeling of the energy transfer processes in the lower atmosphere. Numerical simulation for weather forecasts and the prediction of the temperature and moisture fields require accurate prediction of each of the constituents of the energy budget. Models, though still primitive, suggest the relative importance of the input components to demonstrate the major role of the evaporation field in the development of the urban heat island [Myrup, 1969] and to emphasize the major role of positive advection in the evapotranspiration in arid and semi arid zones [Luther, 1970].
Snow and ice
Authors: Keeler Charles M.
Published: April 2012

An increasing concern for the use of all available fresh water, the promise of increased engineering activity in the Arctic, and a growing demand for winter recreation facilities have all served as practical incentives for snow ice research. This research is in the face of various prophecies that pollution of the atmosphere may result in the melting of global snow and ice, perhaps even within the lifetime of many investigators.
Meteorology of the upper atmosphere
Authors: Leovy Conway B.
Published: April 2012

The four‐year period saw very active work on many aspects of upper atmosphere meteorology: energetics, imposition, thermal structure, and wind systems. Among the most notable achievements, I believe, were the solidification of tidal theory and its successful comparison with observations, the development of the theory of vertical propagation of Rossby waves, the beginnings of a plausible theory of the quasi‐biennial escalation, and realistic new models of the structure of the thermosphere, including the effects of winds.
Progress in research on atmospheric turbulence
Authors: Lilly D. K.
Published: April 2012

In ground‐ and tower‐based instrumentation for direct sensing, few, if any, new concepts have appeared, but steady improvements in technique and reliability have been reported [Dyer et al., 1967; Goddard, 1970; Hicks, 1969; Kaimal, l9687semi; Kaimal et al, 1968; Thurteil et al., 19707semi; Wesely et al., 1970], and comparisons have been made between different kinds of instruments [Businger et al., 19677; Miyake et al, 1970a], leading generally to increased knowledge and confidence in the characteristics of each. More rapid advances occurred in aircraft‐based instrumentation. In particular the utilization of inertial navigation systems by Axford [1968], by the Air Force Hicat program [Crooks et al., 1968] and by the National Center for Atmospheric Research‐Desert Research Institute program [National Center for Atmospheric Research, 1970] is leading to the ability to measure the larger turbulence scales and mesoscales, where much of the important energy generation resides, in levels above the surface boundary layer, Sheih [19717] has effectively utilized hot wire anemometry to measure the microscales of turbulence from an aircraft. Precision radar‐tracked balloons of either the constant‐level type [Angell et al., 1968], or with a roughened surface to improve stability [DeMandel and Scoggins, 1967[, have been used to reveal details of the mesoscale wind field.
Atmospheric optics and radiative transfer
Authors: Howard John N. , Garing John S.
Published: April 2012

The area of atmospheric optics has continued to flourish and burgeon. When we compiled this report four years ago we screened 400 titles for inclusion; this time the number increased to over 900 items, which were found chiefly by checking the contents lists of the five principal journals and utilizing abstracting journals for the rest. We retained about 750 in the bibliography, including a few reports that are available from the Clearinghouse for Scientific and Technical Information, Springfield, Virginia. We omitted most papers relating to the construction or calibration of equipment for atmospheric optical studies. Many papers appeared during this time period on the atmospheres of other planets; we included only papers closely related to the terrestrial atmosphere.
Polar meteorology

The daily views of our earth from outer space are making it increasingly difficult to view the atmosphere as anything but a global entity, and regional meteorology in the classic sense has become a waning branch ofscience. Among the 130 bibliographic references listed below, there is only one study of the type of Reed's [1962] excellent Arctic Forecast Guide, or similar work concerned with synoptic meteorology of the polar regions [Viebrock and Becker, 1968].
Education and the environment
Authors: Fleagle Robert G.
Published: April 2012

Far‐reaching changes are occurring in university education. Some of these changes are intimately related to subject areas within geophysics, but university geophysicists are for the most part playing a passive role in critical examination of curricula and in developing new programs responsive to student interest in environmental problems.

It seems to be that this situation is cause for concern. The following items suggest the issues which call for our thought and attention.

Tenth presentation: James B. Macelwane Award to Carl I. Wunsch
Authors: Press Frank , Stommel Henry , Wunsch Carl I.
Published: April 2012

CARL I. WUNSCH is an exceptionally talented young physical oceanographer, age 29, who combines great strengths in hydrodynamical theory, in knowledge of modern techniques of data processing, in design and carrying out of shipboard field studies at sea, and in his duties as an educator. In his 1966 doctoral dissertation he discovered that the fortnightly and monthly long‐period tides of the ocean are not equilibrium phenomena, as hitherto had always been assumed, but that they are a species of relatively short‐wave length planetary wave , with a marked phase difference in longitude. This new fact was extracted by numerical analysis of long time‐series of tide gauge measurements made in the open ocean.
Noble gases in meteorites
Authors: Bogard Donald D.
Published: April 2012

The measurement of isotopic abundances of the noble gases in meteorites and other extraterrestrial samples became a large and active field during the past decade, especially within the last four years. The five stable noble gases proved to be excellent keys for unlocking the secrets of past physical events in the solar system and are used in studies of such diverse topics as elemental abundances, high‐ and low‐energy nuclear reactions in the solar system, ages of meteorites and the elements, early element fractionation in planetary formation, and many others. For convenience of presentation, recent work in this area is divided in the following summary into four main topics: (1) trapped noble gases, (2) cosmic‐ray interactions, radiation ages, and gas‐retention ages, (3) extinct radionuclides, and (4) lunar studies. In both the text and the bibliography, emphasis is given to work performed in the United States.
Formation times of meteorites and lunar samples

This article summarizes research since the last detailed reviews of meteorite ages by Anders [1963] and Reynolds [1967]. Only crystallization ages based on parent‐daughter isotopic relationships resulting from the decay of naturally occurring radioactive nuclei will be discussed. The basic principles and techniques for age determinations are discussed in many of the papers cited and, along with summaries of scientific results, in several recent books [Dalrymple and Lanphere, 1969; Doe 1970; Hamilton, 1965; Schaeffer and Zahringer, 1966; Faul, 1966]. However, developments in the field have made some of the material in the books obsolete.

Articles on atmospheric winds and waves in the thermosphere and directly related ionospheric effects are compiled in this bibliography. The articles were published during the period from January 1967 to about October 1970 by authors, at least one of whom worked for an American institution. Very roughly, the articles are grouped for citation into the following categories: (1) tides, (2) atmospheric waves, l3) winds, (4) turbulence, and (5) disturbances and ionospheric effects. Of special note is the colloquium held by the National Center for Atmospheric Research [NCAR, 1969], which covered, to some extent, all the categories above.
Hydrogen in the upper atmosphere
Authors: Tinsley Brian A.
Published: April 2012

Over the last 4 years researchers in the United States have made important contributions to the noticeable improvement of our knowledge of hydrogen in the upper atmosphere.

In addition to new data being obtained in rocket, satellite, and ground‐based measurements, improved interpretation of the data and understanding of background effects have lead to more reliable results on hydrogen abundances and diurnal and other variations. Theoretical and observational progress has been made in the understanding of the vertical profiles, the diurnal variations, and the nature of sources and sinks for hydrogen in the upper atmosphere. The effect of hydrogen escape on the evolution of oxygen in the earth's atmosphere has been reinterpreted.

The President's Page: Geophysics and a habitable world (Guest Editorial)
Authors: Wolman M. Gordon
Published: April 2012

In the vast Hall of Congresses within the Kremlin at the opening plenary session of the Fifteenth General Assembly of the International Union of Geodesy and Geophysics, the President of the Union, representatives of Soviet and international science, and the Vice Mayor of Moscow, who welcomed the visiting geophysicists, all spoke of an awareness of the environment, potential perils to the earth and man, and the responsibilities of the geophysicists to this new awareness. Such a single‐minded theme relating geophysics to society is perhaps a unique distinction from any preceding Assembly. The enthusiasm of the speakers raises a number of questions about how geophysicists are to satisfy these new demands. Because, I believe, the answers are not self‐evident, some further observations may be warranted.

When the WAC Corporal rocket first ascended 72 kilometers above the desert sands of New Mexico in 1945 to make measurements of atmospheric pressures, geophysics acquired a new tool that in the course of a quarter of a century has transformed earth sciences into planetary sciences. By the time of the International Geophysical Year in 1957 the power of this new tool was becoming apparent. Data from sounding rockets had substantially improved our understanding of the atmosphere and ionosphere and had unmasked the solar spectrum in the hitherto hidden ultraviolet region.

The National Science Foundation has awarded a $51,000 grant to Emory University, Atlanta, Georgia, to develop and evaluate an experimental program to reorient former defense‐aerospace scientists and technologists into research on societal problems.

The project will involve studies of research needs in public service areas such as waste disposal, health care, transportation, and water pollution. Seven task forces, formed from a total of twenty‐one unemployed technical personnel under the leadership of Emory University faculty members, will conduct the studies and design research projects aimed at the solution of problems in the target areas.
International Symposium on Stochastic Hydraulics, University Of Pittsburgh May 31”June 2, 1971
Authors: Anonymous
Published: April 2012

Stochastic modeling is both an old and a new area of interest in hydraulics. It is old in that turbulence and the problems associated with it have long been recognized. Moreover, because of theoretical and computational difficulties, stochastic components in hydraulics or fluid mechanics have often been used to derive the diffusion‐dispersion coefficients in deterministic differential equations. It is new in that recent advances in the theory of stochastic processes and in the development of computer facilities have produced a surge of interest in the modeling of hydraulic problems. The extent of this recent interest was indicated by the presence of 210 participants, including 29 scientists from 14 countries other than the United States, at the International Symposium on Stochastic Hydraulics.

From the general objectives set forth in the article ‘Geodynamics Project—Development of a U.S. Program’ (May 1971, EOS), the U.S. Geodynamics Committee is focusing its attention on specific aspects of the program. Among the research activities that might be included in the program, the Committee identified several that would require coordinated planning. A corresponding series of temporary working groups is being asked to develop recommendations in these areas by the end of the year. The working groups and their chairmen are listed below. Suggestions from interested scientists are welcome; they should be sent to the relevant chairman (or to the U.S. Geodynamics Committee, National Academy of Sciences, 2101 Constitution Avenue N. W., Washington, D.C. 20418).

Federal study of coastal inundation from storm surges
Authors: Anonymous
Published: April 2012

A new study will be undertaken by the Department of Commerce and the Department of Housing and Urban Development to determine the extent of inland inundation from storm surges. The study is part of a larger survey being conducted by various government agencies for HUD's Federal Insurance Administration to determine the damaging effects of hurricanes and other severe ocean storms on coastal areas. The information is being used as the basis for establishment of federal insurance rates for private structures in shore areas. The data also will be used by the Federal Insurance Administration to prepare maps of vulnerable coastlines as a basis for developing building codes and for land‐use planning.

Ultrascan Company in Cleveland, Ohio, is now marketing an electron microscope which is manufactured by Tesla Company, Czechoslovakia, as the Tesla BS‐242E. It will be marketed here as the Ultrascan/Tesla Tabletop Electron Microscope. The complete system weighs less than 500 pounds and requires less than 15 square feet of table space and a 220V outlet to become a working installation. Since its oil‐diffusion pump is air‐cooled, no cooling water is required.
Electronic states and intraband terahertz optical transitions in InGaAs quantum rods
Authors: Prodanović Nikola , Vukmirović Nenad , Indjin Dragan , Ikonić Zoran , Harrison Paul
Published: April 2012

Strain-dependent eight-band k·p method is used to analyze the electronic structure and intraband optical transitions in self-assembled InGaAs quantum rods in the terahertz range. The calculation of absorption spectra for the growth- and in-plane-polarized radiation shows some similarities to those of quantum well and single quantum dot structures, augmented with contribution from transitions between the dot and quantum well states. The influence of rod height on the electronic structure and the intraband absorption spectra is also investigated. It is found that the energy of maximal terahertz absorption can be tailored by the rod height for both in-plane and in-growth polarized radiation.
Distance-dependent Schwarz-based integral estimates for two-electron integrals: Reliable tightness vs. rigorous upper bounds
Authors: Maurer Simon A. , Lambrecht Daniel S. , Flaig Denis , Ochsenfeld Christian
Published: April 2012

A new integral estimate for four-center two-electron integrals is introduced that accounts for distance information between the bra- and ket-charge distributions describing the two electrons. The screening is denoted as QQR and combines the most important features of the conventional Schwarz screening by Häser and Ahlrichs published in 1989 [J. Comput. Chem. 10, 104 (1989)10.1002/jcc.540100111] and our multipole-based integral estimates (MBIE) introduced in 2005 [D. S. Lambrecht and C. Ochsenfeld, J. Chem. Phys. 123, 184101 (2005)10.1063/1.2079967]. At the same time the estimates are not only tighter but also much easier to implement, so that we recommend them instead of our MBIE bounds introduced first for accounting for charge-distance information. The inclusion of distance dependence between charge distributions is not only useful at the SCF level but is particularly important for describing electron-correlation effects, e.g., within AO-MP2 theory, where the decay behavior is at least 1/R4 or even 1/R6. In our present work, we focus on studying the efficiency of our QQR estimates within SCF theory and demonstrate the performance for a benchmark set of 44 medium to large molecules, where savings of up to a factor of 2 for exchange integrals are observed for larger systems. Based on the results of the benchmark set we show that reliable tightness of integral estimates is more important for the screening performance than rigorous upper bound properties.
Simulation of the runaway electron beam formed in a discharge in air at atmospheric pressure

Published: April 2012

A numerical model is proposed which allows one to describe the dynamics of the fast electrons injected from the head of an anode-directed streamer. The model is based on solving numerically 3-dimensional equations of motion of electrons. In the context of the model, the number of electrons which can be injected from the surface of a streamer is determined by the number of electrons in the Debye layer. Results of numerical calculations show that about 10% of the electrons in the Debye layer are switched to the mode of continuous acceleration. The electrons that have not switched to the runaway mode form a residual space charge cloud, whose dimensions are several centimeters, near a streamer. The space charge screens the streamer tip; therefore, the generation of the runaway electron beam does not resume.
Invited Review Article: Laser vaporization cluster sources
Authors: Duncan Michael A.
Published: April 2012

The laser vaporization cluster source has been used for the production of gas phase atomic clusters and metal-molecular complexes for 30 years. Numerous experiments in the chemistry and physics of clusters have employed this source. Its operation is simple in principle, but there are many subtle design features that influence the number and size of clusters produced, as well as their composition, charge state, and temperature. This article examines all aspects of the design of these cluster sources, discussing the relevant chemistry, physics, and mechanical aspects of experimental configurations employed by different labs. The principles detailed here provide a framework for the design and implementation of this source for new applications.
