(6) In memoriam: Herb Shaw

(1) SPECIAL EVENTS AT THE AGU FALL MEETING

(2)  A MESSAGE FROM YOUR VGP FALL MEETING CHAIR
The VGP portion of Fall AGU is somewhat smaller than in recent years.  There appear to be several reasons for this: (1) Mineral and Rock Physics (MR) contributions now have their own independent session listing, (2) there is increased competition from other meetings, such as the Goldschmidt, and  (3), there are many VGP-related sessions with primary sponsorship in other sections, such as Tectonophysics.

Even so, the VGP program contains a huge number of interesting contributions, both in specially-organized symposia and in general sessions.   Below is a summary of the VGP schedule.  Note that it includes only sessions with primary VGP sponsorship.  We are also co-sponsoring many sessions in Mineral and Rock Physics, Tectonophysics, Seismology, Hydrology, and elsewhere.   See in you San Francisco!

(4) ELECTRONIC PUBLISHING AT AGU

    AGU's  move towards electronic publishing has brought some successes such as the launching of G-cubed, but all this did not happen without hick-ups.  The VGP publication committee solicits opinions on this topic. Please e-mail your concerns and opinions to hstaudigel@ucsd.edu (see also VGP August newsletter, item 9, http://vgp.AGU.org/newsletter_0208.html)

(5) MACELWANE MEDAL NOMINATIONS

    This Fall there were no recommendations from the VGP section for the 2003 Macelwane Medal.  Our committee was convened late and could not identify any candidates that we felt were competitive.  However, we are soliciting suggestions from VGP section members for next year. This medal recognizes significant contributions to the geophysical sciences by an outstanding young scientist.  Candidates must be less than will be 36 years old on January 1 of the year of presentation.

(6)  IN MEMORIAM: HERBERT R. SHAW (1930-2002)
Herbert R. Shaw, Scientist Emeritus with the U.S. Geological Survey’s Volcano Hazards Team, passed away in his home in mid-August from complications of long-standing medical conditions.  He is survived by his daughter Andrea, who lives in Ocean Shores, Washington.  Herb joined the Branch of Experimental Geochemistry and Mineralogy (in Washington, D.C.) of the U.S.  Geological Survey in 1959, upon completion of his doctoral dissertation on mineralogical studies in the Bunker Hill mine, Idaho, under Prof. Charles Meyer at the University of California, Berkeley.  In 1976, Herb transferred to the USGS Western Regional Center in Menlo Park, where he worked until retiring in 1995.

With Herb Shaw's passing, the USGS, and indeed the entire geoscience Community, lost one of its most notable scientific luminaries, whose work profoundly influenced investigations of igneous systems.  He was amazingly eclectic in his scientific interests, including paleontology (while an undergraduate at Berkeley), hydrothermal alteration, experimental geochemistry and petrology, magma rheology, general volcanology, thermal modeling, nonlinear dynamics of the Earth and cosmos, and fractal geometry in linguistics.

Although he was actively involved in various field-oriented projects in his early career with the USGS, through the 1970s and into the 1980s Herb Shaw was primarily known as an experimentalist, conducting innovative laboratory studies of hydrogen osmosis, hydrogen-gas fugacity, diffusion of water in rhyolitic melts, viscosities of magmas, and rheology of basalt.  In collaboration with the staff of the Hawaiian Volcano Observatory (HVO), in 1965 he invented a rotational viscometer and made the first-ever field measurement of the viscosity of basalt in a borehole within the crusted-over Makaopuhi lava lake at Kilauea Volcano.  In 1972, Herb published an empirical method to calculate melt viscosity from chemical composition– a landmark contribution that, with modifications is still in use today.  Beginning in the mid-1970s, Herb focused increasingly on the physics and dynamics of magma transport and their implications for igneous systems, from regional to earth scales.  Herb Shaw definitely was an extraordinary thinker, never settling for the conventional or mundane.  Although often "ahead of their time", and thus controversial, many of his publications were seminal and revolutionary.

Herb Shaw also inspired a number of younger colleagues, notably as a Visiting Professor at Berkeley in the mid-1970s.  During this time, Shaw greatly influenced many graduate students, including some current members of the Volcano Hazards Team (Charlie Bacon, Wes Hildreth), with his thought-provoking seminars, quick wit, and easy company.  Among these students was Frank Spera (now Professor at UCSB), who pursued a career in magma rheology as a result of Shaw's papers and personal interaction with Herb Shaw.

Herb's work also had important practical applications in the USGS Geothermal Research Program.  He and Robert L. Smith (former USGS Geologist) devised a realistic model of igneous-related geothermal systems that linked the size, longevity, and cooling of magma reservoirs.  This model and its ramifications served as the scientific foundation for the USGS' national assessments of geothermal resources in 1975 and 1979.  In the late 1970s, Herb was tapped by the Nuclear Regulatory Commission, when he served as a consultant to Sandia National Laboratories on risk-assessment methodology and strategies for management of high-level radioactive waste.

In 1980, Shaw turned to analyses of fault and stream branching, self-similarity, attractor theory, chaos, fractals, and other unconventional approaches.  Again, he was far ahead of mainstream thinking at that time in applying multidisciplinary nonlinear dynamics to geological and cosmological processes.  In a highly productive collaboration lasting into the early 1990s, Herb worked with Bernard Chouet (now a member of the USGS Volcano Hazards Team) and published a series of high-impact papers applying nonlinear dynamics and fractal theory to seismic tremor, gas-piston events, and magma transport at Kilauea Volcano.  During this same period, Shaw and James G. Moore (now Scientist Emeritus, Volcano Hazards Team) published a provocative article in Eos (1988) linking magmatic heat from the global mid-oceanic ridge system and the El Niño cycle.  More recently, Herb produced a 744-page book titled Craters, Cosmos, and Chronicles: A New Theory of Earth, published by Stanford University Press in 1994.  While this ambitious and comprehensive volume is not easily read and understood by the casual reader, scholars in the cosmology field have pronounced it as one of the most compelling works in the 20th century.

The career-long contributions of Herb Shaw, the scientist, are well recognized and appreciated within and outside the USGS.  He received the Meritorious Service Award of the Department of Interior and was a Fellow of the American Geophysical Union and the Geological Society of America.  However, less is known about Herb Shaw, the individual, in part because he was a very private person and in part because, for most of his career, he had the habit of sleeping days and working nights.  However, his friends and close associates knew him to be an approachable guy generous to a fault, witty and engaging in conversation, extremely well read, and an avid follower of the arts and culture scene.  Herb also was a talented poet, gifted sculptor and painter, and a superb tennis player with a huge serve.  In every aspect of his scientific and private life, Herb Shaw embodied the Renaissance man, and he will be missed by all those who knew or worked with him.
