Summons Department of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA, and National Aeronautics and Space Administration (NASA) Astrobiology Institute, MIT Team ABSTRACT Many of the discoveries made in geochemistry over the last 50 yr have been driven by technological advances that have allowed analysis of smaller samples, attainment of better instrumental precision and accuracy or computational capability, and automation that has provided many more data. These advances occurred during development of revolutionary concepts, such as plate tectonics, which has provided an overarching framework for interpreting many geochemical studies. Also, spacecraft exploration of other planetary bodies, including analyses of returned lunar samples and remote sensing of Mars, has added an additional dimension to geochemistry. Determinations of elemental compositions of minerals and rocks, either through in situ analysis by various techniques (e.g., electron microprobe, secondary ion mass spectrometry [SIMS], synchrotron X-ray fl uorescence [XRF], laser ablation) or bulk analysis (e.g., XRF, inductively coupled plasma–atomic emission spectrometry [ICP-AES], inductively coupled plasma–mass spectrometry [ICP-MS]), have become essential approaches to many geochemical studies at levels of sensitivity and spatial resolution undreamed of fi ve decades ago.

  • Robert A. Berner Autobiography, American Journal of Science
    [American Journal of Science, Vol. 313, January, 2013,P.1–60, DOI 10.2475/01.2013.01] American Journal of Science JANUARY 2013 FROM BLACK MUD TO EARTH SYSTEM SCIENCE: A SCIENTIFIC AUTOBIOGRAPHY ROBERT A. BERNER Department of Geology and Geophysics, Yale University, P.O. Box 208109, New Haven, Connecticut 06520-8109 dedication To my wife, Elizabeth Kay Berner, for her unstinting encouragement and understanding throughout the many years of my devoting myself to my research, and for her collaboration in the writing of three books. PROLOGUE This autobiography covers the past 55 years of my research in geochemistry. I try to show how chemical principles can be applied to a wide variety of geological problems, ranging from iron sulfide mineralogy, to carbonate chemistry in the oceans, to silicate mineral surface chemistry during weathering, to biogeochemical changes during early diagenesis, to plants and weathering, to models for the evolution of atmospheric oxygen and carbon dioxide. This may seem excessively broad but my approach to science has been and will be eclectic for which I do not apologize. My guiding principle is “How can chemical measurement or chemical theory solve a given problem?” PART I. THE EARLY YEARS, 1953–1979 THE MAKING OF A GEOCHEMIST The Beginning I was strong in math and science in high school, so I entered Purdue University in 1953 with the intention of majoring in chemistry. I became completely dissatisfied with Purdue after about two months and decided to transfer to the University of Michigan after only one semester. At Purdue they kept pushing me towards engineering and, more importantly, there was a large lack of female students there.
