"Don Lynn Anderson (March 5, 1933 – December 2, 2014) was an American geophysicist who made significant contributions to the understanding of the origin, evolution, structure, and composition of Earth and other planets. An expert in numerous scientific disciplines, Anderson's work combined seismology, solid state physics, geochemistry and petrology to explain how the Earth works. Anderson was best known for his contributions to the understanding of the Earth's deep interior, and more recently, for the hypothesis that hotspots are the product of plate tectonics rather than narrow plumes emanating from the deep Earth. Anderson was Professor (Emeritus) of Geophysics in the Division of Geological and Planetary Sciences at the California Institute of Technology (Caltech). He received numerous awards from geophysical, geological and astronomical societies. In 1998 he was awarded the prestigious Crafoord Prize by the Royal Swedish Academy of Sciences along with Adam Dziewonski. Later that year, Anderson received the National Medal of Science. He held honorary doctorates from Rensselaer Polytechnic Institute (where he did his undergraduate work in geology and geophysics) and the University of Paris (Sorbonne), and served on numerous university advisory committees, including those at Harvard, Princeton, Yale, University of Chicago, Stanford, University of Paris, Purdue University, and Rice University. Anderson's wide-ranging research resulted in hundreds of published papers in the fields of planetary science, seismology, mineral physics, petrology, geochemistry, tectonics and the philosophy of science. He continued to work and publish until his death. His widely known textbooks, Theory of the Earth, and New Theory of the Earth are regarded by colleagues as compelling syntheses of the origins of the Earth and its inner workings by one of the great geophysical authorities of our time. Life and main scientific contributions Receiving the National Medal of Science from President Bill ClintonDon and Nancy Anderson celebrating their 50th Wedding AnniversaryThe cover of Anderson's book, New Theory of the Earth illustrates the ongoing debate among geophysicists over whether volcanoes are the natural outcome of plate tectonics or emanate from the deep Earth through narrow plumes.Born in Frederick, Maryland in 1933, Anderson moved to Baltimore when he was six. He graduated from Baltimore Polytechnic Institute then attended Rensselaer Polytechnic Institute (RPI) where he earned a Bachelor of Science in geology and geophysics in 1955. He then worked in the oil industry in California, Montana and Wyoming, and served in the Air Force in Massachusetts and Thule, Greenland before moving to California, where he received a Ph.D. in geophysics and mathematics at Caltech in 1962. He spent most of his subsequent academic career at Caltech's Seismological Laboratory, becoming its second longest serving director from 1967 to 1989. He was married to Nancy Ruth Anderson, had two children, Lynn Anderson Rodriguez and Lee Weston Anderson, and four granddaughters. Anderson began his scientific career while serving in the U.S. Air Force. In Greenland, he studied the properties of sea ice. Anderson was charged with determining whether the ice was strong enough to withstand the landing of heavy aircraft. In working with his colleague, Dr. Wilford Weeks, on scientific papers resulting from the research, it became clear to Anderson that he needed more education. He chose to attend Caltech in geophysics. Anderson's thesis focused on the anisotropic, or directionally dependent, properties of the mantle. It analyzed wave propagation in layered complex media. Prior to Anderson's work, seismologists had assumed that the Earth's interior behaved like glass, and was isotropic. After completing his Ph.D. in 1962, Anderson joined the faculty at Caltech and moved on to other areas of study, writing papers on the composition, physical state, and origin of the Earth as well as other planets. Much later in his career, he returned to the effects of anisotropy and partial melting and the presence of fluids in the upper mantle. He and his colleagues developed methods for taking into account anisotropy and the non-elastic behavior of seismic waves to explain how the Earth works. The technical terms for the subjects of his studies are anharmonicity, asphericity, anelasticity, as well as anisotrophy. In other words, the Earth is not an ideal, elastic sphere. During his more than 50-year career, Anderson published papers on the composition and origin of the Moon, Venus and Mars as well as Earth. He was a principal investigator on the Viking mission to Mars in 1971. Anderson and his collaborators investigated the relations between the behavior of mantle rock under high pressures and temperatures, phase transformations of mantle minerals, and the generation of earthquakes. They contributed significantly to the understanding of tectonic plate motions by mapping convection currents in the Earth's mantle using seismological methods. These studies led to the development of the Preliminary Reference Earth Model (PREM), which provides standard values for Earth's important properties, including seismic velocities, density, pressure, attenuation, and anisotropy as a function of planetary radius and wavelength. PREM is now the standard reference model for the Earth. This work was cited when Anderson, along with his colleague Adam Dziewonski of Harvard University, were awarded the Crafoord Prize in 1998 in Sweden. By taking into account the physics and thermodynamics of Earth materials under the high temperature and pressure conditions in the deep interior, Anderson developed theories that depart from mainstream scientific speculations. In particular, Anderson showed that the standard geochemical and evolutionary models for the Earth are flawed because they violate the laws of thermodynamics in ways that would make Earth behave as a perpetual motion machine. Anderson likened these models to Rudyard Kipling’s “Just-So Stories,” and pointed out that these flawed theories are perpetuated when countervailing evidence is explained away as anomalies or paradoxes. Anderson's models are based on physics and thermodynamics as well as geophysics, and stand up to observations and evidence-based tests. Anderson developed an alternative model of the mineralogical and isotopic composition of the mantle. The Earth had a high-temperature origin and has been chemically stratified since it accreted 4.5 billion years ago. Conventional scientific wisdom is that the entire mantle is largely made up of olivine-dominated peridotite, some of it primordial material. Anderson, on the other hand, showed that the mid-mantle is composed of piclogite, a pyroxene and garnet- rick rock. Counter to prevailing scientific views, Anderson argued that the deeper layers of the mantle are dense and refractory and unable to rise to the surface or to produce basalts. Anderson suggested that all basalts are produced in the upper mantle. These ideas evolved from the integration of geochemistry, petrology, seismology, and thermodynamics, while standard models are based only on one or two of these disciplines and many assumptions. Anderson also challenged traditional scientific views on how volcanoes are formed, particularly, the theory of convective mantle plumes in the Earth, as proposed by W. Jason Morgan, Anderson argued that the so-called mantle plume hypothesis is invalid and that hotspots and oceanic islands such as Hawaii or Iceland are, instead, the normal products of plate tectonics. While many geochemists believe that volcanoes stem from narrow plumes coming up from just above the Earth's core, Anderson showed that they can be explained entirely by chemical and mineralogical anomalies in the upper mantle. Moreover, Anderson pointed out that all demonstrations of the mantle plume hypothesis violate the basic laws of thermodynamics because they rely on a constant supply of heat coming from the deep Earth or even from outside the Earth. Anderson, on the other hand, accepted the classical view that the Earth's interior is cooling and that volcanoes simply tap a layer of melted rock that exists in the upper mantle, or outer shell of the Earth. It is through the movement of the plates that the magma is allowed to reach the surface through fracture zones, rifts, volcanoes and so-called hot spots. Anderson also considered that plate tectonics is a natural result of a planet being cooled from above.Harding, Stephan. Animate Eart. Science, Intuition and Gaia. Chelsea Green Publishing, 2006, p. 114. Although his work was based on seismology, classical physics and thermodynamics as well as his knowledge of the Earth's interior, Anderson's theories are considered to be controversial because they depart from the prevailing ideas developed by the geochemical community and which are widely cited in influential publications such as Nature and Science. An active website, mantleplumes.org, is devoted to the challenge by Anderson and his colleagues to standard, or text-book explanations of volcanoes and Earth dynamics. Anderson's multidisciplinary approach, combined with his expertise in geophysics, geochemistry, solid-state physics, and thermodynamics, enabled him to explain the evolution and structure of the Earth in ways that challenge accepted ideas of his time. Colleague Seth Stein of Northwestern University said of Anderson's New Theory of the Earth: “An old adage says that there are no true students of the Earth because we dig our small holes and sit in them. This book is a striking counter example that synthesizes a broad range of topics dealing with the planet’s structure, evolution, and dynamics. Even readers who disagree with some of the arguments will find them insightful and stimulating.” Anderson died in Cambria, California on December 2, 2014 from cancer, at the age of 81. Technical details * Showed that anisotropy and anelasticity were important in the propagation of seismic waves in the Earth. * Introduced frequency dependent and polarization effects into modern seismology. This made it possible to resolve discrepancies between various types of seismic data (body waves, normal models; Rayleigh-Love wave discrepancy) and to combine all types of data into a single inversion. * Developed theory for frequency dependence of both wavespeeds and anelasticity (Q) and applied this to the mantle and core (Absorption Band Model). * Developed methods for inverting surface waves for anisotropic structures (Universal Dispersion Curves). * Showed (with Minster) how microphysics could explain how short period phenomena could be related to long term rheology. * With Nataf, Nakanishi, Tanimoto, Montagner, Regan developed first 3D structures of the anisotropic mantle.
