Redefining success
Authors: Cain Joe
Published: October 2011

At the recent IUGG meeting in Vancouver, I was impressed at observing that speakers are now more willing to reveal the ways in which their research has problems, in place of only showing the results of successful work. Indeed, the hallways of such events are the forums where the “real” science is discussed.

What brought this to my attention was a paper by Bob Langel (National Aeronautics and Space Administration Goddard Space Flight Center, Greenbelt, Md.), who illustrated the (perhaps temporary) inability to have satellite and surface data modeling results agree to his satisfaction. Such candor is commendable since it helps the more insecure beginning Ph.D.s to remember that all experiments are not successful in achieving the initial “objectives,” but then they would not be “experiments” would they? Reticence in considering such presentations is fueled by the specter of a listener publically pointing out some obvious flaw in the work and the resulting ego damage to the speaker.

Proposed change in the AGU Bylaws
Authors: Anonymous
Published: October 2011

At its meeting on May 19, 1987, the AGU Council gave initial approval to an amendment to Bylaw 14, relating to election procedures, to clarify these procedures and bring them into conformity with Robert's Rules of Order. The changes are as follows:

Add a new Article 14d to read: “Elections shall be accomplished by mail.”

Add Article 14e to read: “If more than two candidates are nominated, voters shall be required to rank candidates in order of their preference. In tallying such votes, if no candidate has a majority of the first‐place votes, then the candidate with the fewest first‐place votes will be eliminated and the second‐place votes on those ballots distributed among the other candidates and this process repeated until one candidate has a clear majority.”

Change to Article 14f the old 14d, which reads: “Results of the general election shall be announced at the Annual Business Meeting.”

Notice of this proposed change is given in accordance with Article 126 of the Statutes, which requires that proposed amendments to the Bylaws be published in an AGU publication of general circulation no less than 30 days prior to a second consideration by the Council. The Council will consider this proposal for final passage at its December 1987 meeting in San Francisco, Calif.

Voyager: 10 years of exploration
Authors: Maggs William Ward
Published: October 2011

On September 5, 1987, Voyagers 1 and 2 kept moving at 15 km/s or so, something they have been doing well for a decade. Last month the Voyager mission marked its 10th anniversary of planetary exploration, as well as the fact that the two spacecraft already traveled nearly 4 billion miles (∼6 billion km) each. On the way they have provided a staggering amount of information about the outer planets in the Solar System, and their work is not yet finished. Soon Voyager 1 will rocket out of the solar system, its instruments in search of the heliopause, the end of the solar wind, and Voyager 2 will be propelled from its recent encounter with Uranus toward a polar flyby of Neptune in August 1989.
The Ocean of Truth: A Personal History of Global Tectonics
Authors: Frankel Henry
Published: October 2011

H. W. Menard died on February 9, 1986. His professional legacy includes much of his scientific work in unearthing the floor of the Pacific Ocean, his former students, and his work in the history of science. In addition to his earlier endeavor into the history and sociology of science, Science Growth and Change (Harvard University Press, Cambridge, Mass., 1971), Menard leaves us The Ocean of Truth. Unable to stop himself from doing research, he corrected the galley proofs for The Ocean of Truth during the last days of his life, in his hospital bed, while dying of cancer. I include Menard's work in the history of science within his professional legacy, since Menard did not approach the history of science as a retired scientist who decides to write, with memory as his only guide, about his and his fellow scientists' research. The Ocean of Truth is a serious and successful attempt to recount the rise of oceanography and its bearing upon the recent revolution in the Earth sciences.

Thinning ice may signal changes
Authors: Anonymous
Published: October 2011

The thinning of ice on Antarctica's Lake Hoare over the past decade may be a signal of profound climatic change, at least on the local level. Scientists have measured a 2‐meter decrease in the thickness of surface ice on the lake, as well as rising water levels, during the 10‐year study. The same trend has been observed at other lakes in the Taylor Valley, where the study is taking place.

According to George M. Simmons of Virginia Polytechnic Institute (Blacksburg, Va.), a member of the study group, the 20‐cm/yr thinning rate and higher water levels suggest increased input from glacial meltwaters into Lake Hoare. The lake is in the dry valley region of Antarctica, where the ground is icefree and surface temperatures sometimes climb above freezing in the austral summer. The ice‐covered lake is essentially closed to losses of water or other material and is “a terrific climatological library,” says Simmons. “Almost everything that goes into it stays in.”
1987 VGP Award Goes to Fred Frey
Authors: Haskin Larry
Published: October 2011

Fred Frey dropped into my office in 1961 to talk about thesis research. Fred was a chemical engineer who, after a year's experience in industry, decided to get a Ph.D. in chemistry. After we talked, Fred decided that a combination of physical chemistry, radiochemistry, and geochemistry could interest him for the next few years. I guess he was right, since he's still at it. He defended his dissertation in 1966 and joined the faculty of Earth, Atmospheric, and Planetary Sciences at MIT [the Massachusetts Institute of Technology], and he is still there.

For his thesis, Fred chose to survey mafic and ultramafic rocks for their rare earth element (REE) concentrations. Back then, we did not know what typical REE relative abundances were in Earth's most voluminous intrusive and extrusive rocks—peridotites and basalts. Would basalts, like shales, turn out to be relatively enriched in the lighter REE, compared to the distribution in chondrites? Would peridotites have relative abundances like those of chondrites, or would they be depleted in light REE in complement to crustal materials?
Geophysical Methods in Geology
Authors: McNutt Marcia
Published: October 2011

This updated version follows the intent of the earlier edition by introducing techniques in geophysical exploration to undergraduate students in either geology or geophysics. The emphasis is on crustal geophysics, as it is this aspect that most strongly interfaces with geology. The list of topics covered is very broad, including seismic, gravity, magnetic, paleomagnetic, electrical, electromagnetic, radiometric, and geothermal methods. Sharma has done a credible job in bringing the material up to date, with at least 10% of the references corresponding to publication dates in the 1980s. The lingering out‐of‐fashion concepts are confined to subjects beyond Sharma's principal areas of expertise (e.g., marine geophysics, on p.114: “The crust is thinnest beneath the deepest oceans and tends to thicken beneath the midocean ridges…”).
Groundwater bills
Authors: Anonymous
Published: October 2011

U.S. lawmakers have become concerned about groundwater problems in the United States, and thus the contamination of groundwater is rapidly becoming one of the hottest issues of 1987 and probably for many years into the future. The 100th Congress has seen a proliferation of bills relating to various problems involving groundwater: need for more data, funding of research, and development of standards for groundwater quality. Because round 50% of the nation's drinking water is obtained from groundwater, the available support is dependent not only upon the available quantity but also on the quality of that supply.

Because groundwater quality in general and groundwater contamination in particular provides such complex problems, final legislation probably will emphasize more research and more data collection. At present, a bill, the National Ground Water Contamination Research Act, has been introduced in the House of Representatives by Rep. Sam Gejdenson (D‐Conn.), and a companion bill has been introduced in the Senate by Sen. David Durenberger (R‐Minn.). These bills renew action on a groundwater research bill that passed the House but not the Senate near the end of the 99th Congress. The bills address not only research but also promote a national program for the assessment of groundwater quality and a national clearinghouse for groundwater information.

A special session entitled “Flow and Transport Through Unsaturated Fractured Rock I, II, and III,” which involved a day and a half of both invited and contributed technical presentations as well as a panel discussion, was held during the 1986 AGU Fall Meeting in San Francisco. The session was in response to a request by Soroosh Sorooshian (University of Arizona, Tucson), the Fall Meeting Hydrology Session Chairman, to Daniel D. Evans (University of Arizona, Tucson), and Tom Nicholson (U.S. Nuclear Regulatory Commission, Washington, D.C.), the session chairmen, who had organized an earlier research symposium sponsored by the Nuclear Regulatory Commission on this same topic in Tucson in January 1986.
JGR‐Solid Earth and Planets editor William Kaula
Authors: Anonymous
Published: October 2011

Since early 1987, the Journal of Geophysical Research‐Solid Earth and Planets (JGR‐Solid) has been under the direction of seven editors. William M. Kaula of the University of California, Los Angeles (UCLA), has the title of Editor in Chief. But he says, “I regard my position not as a chief, but as a chair: one who leads a group of equals in reaching consensuses as to policy and mode of operations.”

There are six sections of JGR‐Solid. Authors can submit papers to Kaula or any of the six section editors, and all seven have power of final decision. According to Kaula, the nature of the journal requires cooperation in editing. “JGR‐Solid is not only voluminous, it is diverse, with a considerable range in techniques and approaches in the six sections that it serves. It is a tremendous j ob for one person to be editor; his decisions must depend appreciably on the technical judgements of the associate editors.” Nearly 5300 journal pages were published in JGR‐Solid in 1986, and the number is expected to increase under Kaula and the six associate editors.

The March 2, 1987, earthquake near Edgecumbe, North Island, New Zealand
Authors:   Staff, New Zealand Department of Scientific and Industrial Research
Published: October 2011

A shallow crustal earthquake of magnitude ML 6.3 occurred on March 2, 1987, at 01:42:34 UT, close to the town of Edgecumbe, North Island, New Zealand. The focal depth was estimated to be 12±1 km. Surface deformation included multiple surface breaks. The main rupture was 7 km long and had a maximum of 2 m vertical displacement.

Significant damage, estimated at over NZ$130 million (U.S$75 million), occurred to property in the surrounding region. Fortunately, few casualties and no deaths occurred as a direct result of the earthquake, partly because a magnitude ML) 5.2 foreshock occurred about 7 minutes before the main shock.

[Reply to “Space Station?” by L. H. Meredith] Way station
Authors: Warner Jeffrey L.
Published: October 2011

I agree with Les Meredith's statement of valid and nonvalid objectives for the space station. The problem with the space station that NASA is proposing is that it is designed to a nonvalid objective, specifically microgravity experimentation. I would support a space station that addressed the valid objective of a way station, but I cannot support NASA's current design.

Meredith states that the space station can only be justified as a political action by the United States to reassert its preeminence in space. Meredith lists a valid objective of creating a permanent manned presence to provide a “way station” for future Earth orbital activities and Solar System exploration. Meredith further argues that two other classes of space station objectives, namely a microgravity research and manufacturing facility and an Earth and astronomical remote sensing platform, are not valid because those activities can be better carried out by non‐space station means.

Published: October 2011

The U.S. Navy has established the Institute for Naval Oceanography (INO, in NSTL, Miss.), which has as its principal goal the development and demonstration of mesoscale eddy‐resolving ocean prediction systems on a global basis. Data bases of meteorological and oceanographic variables are a component in understanding and predicting the dynamics of atmospheric and oceanic systems. Thus high‐quality, well documented data bases are vital for the development of ocean prediction systems and are crucial for the achievement of INO's mission. In recognition of this, the INO sponsored the first workshop on archived ocean data bases to support research, development, and operations in ocean prediction and modeling. The workshop did not explicitly address real‐time data bases, which warrant separate treatment.

The system is currently capable of measuring baselines of a few hundred kilometers' length within an accuracy of a few centimeters, and further improvements are expected.
[Comment on “Seismology in the days of old” by Inge Lehmann] The Lehmann discontinuity
Authors: Anderson D. L. , Bolt B. A. , Morse S. A.
Published: October 2011

Recent reflections by Inge Lehmann on her discovery of the inner core (Eos, January 20, 1987, p. 33; see also Bolt [1987, 1982]) remind us that this outstanding Earth scientist is now in her 100th year. The inner core boundary (ICB) is one of the three great seismic‐compositional discontinuities that divide Earth into crust, mantle, core, and inner core. The other two discontinuities are well known by names honoring their discoverers, Andrija Mohorovicic and Beno Gutenberg. In this tradition, it is fitting that the ICB be called the Lehmann Discontinuity in honor of its discoverer.

That Earth is constantly changing has been known since the beginnings of human reflections on the nature of our environments. The minute‐by‐minute changes in winds and clouds and the long‐term trends in the climate of the continents, the rapid fluctuations in the humidity of the air and the sudden arrival of monsoons and tropical storms, the seasonal greening of grass and changing vegetation patterns around the globe, the rapidly spreading ripples in ponds and the slow meanderings of the Gulf Stream, the bursts of violent snow storms and the waxing and waning of the polar ice caps, all testify to the dynamic nature of the environments.
Antarctic ice is smaller

Published: October 2011

The Ross Ice Shelf, straddling the protected waters of the Ross Sea off Antarctica, has produced an iceberg three times the size of Long Island. A massive raft of ice about 208 km long, 53 km wide, and 250 m thick calved cleanly off the shelf in late September or early October and is currently moving away from the coast at about 200 m/hour, heading west and, of course, north. It is the largest piece of floating ice on record, and if it can stay in one piece for a trip to slightly lower latitudes, it may drift into westerly ocean currents and be carried in a victory lap all the way around the continent.

An international group of scientists organized under the aegis of the International Union of Geological Science (IUGS) will try to inventory existing geoscience data bases around the world and test the waters for a new information service based on ongoing research.

The IUGS Joint Working Group, composed of geologists and information scientists from Czechoslovakia, the Soviet Union, France, Italy, and the United States, met September 14–16, 1987, in Vienna, Austria. The group put together a questionnaire to help determine the extent and distribution worldwide of factual and bibliographic information in the geosciences. Ghassan Rassam, group member and AGU Director of Public Information and Marketing, said, “Our intent is to increase the availability of scientific information to earth scientists, and to decrease the redundancy of different data bases now in place.”
Ten proposed rules of numerical diagrams
Authors: Court Arnold

Diagrams have been used for 3 centuries to present numerical information succinctly. Yet no complete, specific rules are available for their preparation, similar to the rules of grammar, syntax, and spelling of language. Some guidance is offered in the dozen books on graphics published in the United States in the past 40 years, and fragments appear in textbooks and manuals. But none of these is complete or consistent, and each offers at least one glaring contravention of the basic tenets of mathematics and logic.

During the past year several questions concerning the publications process have come to the attention of the Publications Committee. These questions have made it clear to us that some members of AGU may not be familiar with some key elements of AGU's philosophy toward publication. Since the publications activities are so important to each member and to the Union as a whole, we believe that a brief overview of the responsibilities of the three primary groups involved in the publication process is in order. Most of what we say here would apply to any scientific journal or at least any scientific journal published by a learned society. Some aspects are specific to AGU.
The evolution of nonlinear periodicity, illustrated by the sine circle map
Authors: Anonymous
Published: October 2011

The sine circle map illustrates periodic patterns discussed in the main article (“The Periodic Structure of the Natural Record, and Nonlinear Dynamics”). These patterns are generated by a recursion algorithm that describes the iterations (ticking) of a nonlinear clock (for example, a clock driven by a nonlinear pendulum). The increments of arc swept out by a clock hand or pointer per unit time (per tick) in such a device, as shown schematically in Figure 1, are not linearly proportional to time; that is, they do not fall at equally spaced tick marks around the clock face. The circle map has served as a model for many complex systems of coupled oscillation in the literature; these systems include experimental studies of the damped driven pendulum, charge density waves in semiconductors, Josephson junctions (coupled superconductors), and Rayleigh‐Bénard convection “for example, Jensen et al., 1984, 1985”.

Authors: Schneider Otto
Published: October 2011

Daniel A. Valencio, Professor of Geophysics at Buenos Aires University, died on May 28, 1987, shortly before his 59th birthday. A pioneer of paleomagnetism and tectonophysics in Latin America, Valencio was an outstanding teacher and investigator in these disciplines.

His original employment as an exploration geophysicist in Argentina and Cuba led him to become interested in solid Earth sciences in general in the 1960s. At that time, he laid the foundations of the Laboratory of Paleomagnetism at the Departamento de Ciencias Geologicas of Buenos Aires University. This facility has become a very active center of research and teaching, with emphasis on an interdisciplinary approach that includes the participation of an important group of pupils.
Sand sheets show chevrons

In Saharan Africa, sand sheets stretch in virtually flat expanses for hundreds of kilometers. The sheets have been considered devoid not only of life but of regional landforms that might provide insight into the wind‐driven processes of erosion and transport by which deserts sustain themselves and grow. Now a fresh, computer‐enhanced look at satellite images of sand sheets in Egypt and Sudan by Ted Maxwell of the Smithsonian Institution's Center for Earth and Planetary Studies (Washington, D.C,) and C. Vance Haynes of the University of Arizona (Tucson) has led to the discovery of huge, flat sand dunes.

Both the 1987 and 1988 AGU Plans adopted by the Council have included initiation of activities to influence public policy and decision making on subjects that are important to advance geophysics. Three panels to formulate Union positions for Council approval have been appointed by the President. These have been announced in previous issues of Eos:

Earmarking and Fencing: December 8, 1987, p. 1647

Geomagnetic Observatories: December 22, 1987, p. 1793

Planet Earth Initiative: December 22, 1987, p. 1793

So that the positions established represent the broadest concensus, it is important that AGU members' views on these issues be communicated to section officers, panel members, or to the full membership through letters to the Eos Editor in Chief.
Aquarius dives in Virgin Island

Published: October 2011

Scientists working on the ocean floor have a new sea bottom home in Aquarius, the advanced habitat launched in November 1987 by the National Oceanic and Atmospheric Administration (NOAA). Aquarius has been placed on the seafloor in Salt Water Canyon off St. Croix in the U.S. Virgin Islands and is expected to remain there for 1 o r 2 years. During that time, teams of six scientists will be able to live in the habitat and work on the seafloor for up to 9 hours each day. Aquarius, which houses labs, sleeping quarters, and a galley in its 13 × 3.6 × 5‐meter space, cost NOAA $5.5 million.

Twelve minority students were named AGU Scholars for the 1987–1988 academic year. They are among the recipients of scholarships under the American Geological Institute (AGI) Minority Participation Program. This designation recognizes AGU's continued strong support and substantial contribution to this program. Four of these students were designated AGU Sea Grant Scholars because part of the support for this program comes from a matching grant from the National Oceanic and Atmospheric Administration's Sea Grant Program, which is aimed at increasing the number of minority students studying in fields related to the development of marine and coastal resources. The AGU Scholars, who are all in courses related to the broad areas of Union interest,

Nearly 740 Black, Native American, Pacific Islander, and Hispanic students applied for the fellowships, which are based on merit. Honorable Mention went to 214. Twenty more minority students received awards for next year than in 1987, part of an NSF plan to double the number of the fellowships over several years.
January and February streamflow
Authors: Anonymous
Published: October 2011

With 72% of the 191 stations in the United States, southern Canada, and Puerto Rico reporting streamflow in the normal to above normal range, 1988 had the second‐lowest streamflow for a January in the last 6 years, U.S. Geological Survey hydrologists report. In December 1987, 75% of the stations had reported flows in the normal to above normal range, and 75% of reportin g reservoirs had contents near or above average. In January 1988, 74% of the reservoirs had contents in that range.

The Pacific northwest continued to experience below‐normal streamflow conditions and to have l ow reservoir contents, while the southern Great Plains of Kansas, Oklahoma, and contiguous states had persistently high streamflow. The combined flow of the Mississippi, the St. Lawrence, and the Columbia rivers (the three largest rivers in the contiguous United States) rose 51% from December to January to reach an average of 1,214,800 cubic feet per second (cfs), which is 22% above median.

Breakthrough in Arctic deep‐sea research: The R/V Polarstern Expedition 1987
Authors:   Polarstern Shipboard Scientific Party
Published: October 2011

During summer 1987, the R/V Polarstern of the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Federal Republic of Germany (FRG), succeeded in penetrating the eastern Arctic ice pack as far north as the Nansen‐Gakkel Ridge in the central eastern Arctic Basin. Our northernmost location, at 86°H′N (Figure 1), was further north than any surface vessel dedicated to marine research has attained previously, although Soviet nuclear‐powered ice breakers have managed to penetrate to the North Pole. Prior to this cruise, most knowledge about the eastern Arctic Basin came from remote sensing techniques, Nansen's Fram expedition during 1893–1896 [Bøggild, 1906; Gran, 1904; Nansen, 1902, 1904, 1906], Russian ice camps [Gordienko and Laktionov, 1969], the U.S. ice island camps Fram I‐Fram IV, 1979–1982 [Hunkins et al, 1979; Baggeroer and Dyer, 1982; Manley et al, 1982; Kristoffersen, 1982; Kristoffersen et al, 1982; Kristoffersen and Husebye, 1985], and explorations by submarines.

Papers given at the 1988 AGU Spring Meeting continue to make news. Representatives from 12 magazines, 5 newspapers, 2 wire services, and a TV station used the press room and attended the 6 news conferences. The journalists were attracted to the meeting, held May 16–20 in Baltimore, Md., by 6 press releases mailed out by the AGU public information staff in the 2 months before the meeting. Correspondents from as far as Sweden and Japan joined U.S. reporters from San Francisco, New York, Washington, D.C. and Baltimore.

A count of clippings received by June 6 shows that by May 17, the second day of the meeting, newspapers in 36 states had published articles; that translates to a potential readership of 5 million. News clippings are still arriving, so figures are preliminary.
