Sutton, Ph.D., Chair _________________________________ Jeffrey C. Sanders, Ph.D. _________________________________ Lawrence B. A. Hatter, Ph.D. ii ACKNOWLEDGEMENT This thesis has been years in the making and is the product of input from many, many different people. I am grateful for the support and suggestions of my committee—Matt Sutton, Jeff Sanders, and Lawrence Hatter—all of whom have been far too patient, kind, and helpful. I am also thankful for input I received from Michael Gordin at Princeton and Helen Anne Curry at Cambridge, both of whom read early drafts and proposals and both of whose suggestions I have been careful to incorporate. Catherine Connors and Carol Thomas at the University of Washington provided much early guidance, especially in terms of how and why such a curious topic could have real significance. Of course, none of this would have happened without the support of Bruce Hevly, who has been extraordinarily generous with his time and whose wonderful seminars and lectures have continued to inspire me, nor without Graham Haslam, who is the best teacher and the kindest man I have ever known. -
Bert Bolin: Meteorologist and First Chair of the IPCC Who Cajoled the World Into Actio

Page 1 of 2 l Home ¡ > News n > People n > Obituaries Bert Bolin: Meteorologist and first chair of the IPCC who cajoled the world into action on climate change Published: 05 January 2008 Bert Richard Johannes Bolin, meteorologist: born Nykoping, Sweden 15 May 1925; Professor of Meteorology, Stockholm University 1961-90; Chair, Intergovernmental Panel on Climate Change 1988-97; married Ulla Frykstrand (two sons, one daughter; marriage dissolved 1979); died Stockholm 30 December 2007. The Swedish meteorologist Bert Bolin was one of the giants of the climate-change debate. For 30 years he, more than any other individual, made sense of the rising tide of research emerging from weather observations and computer models, and cajoled a reluctant world into recognising the urgency of the issue. Between 1988 and 1997, Bolin chaired the Intergovernmental Panel on Climate Change. These were the years of the IPCC's most crucial work, establishing a broad scientific consensus for political action, and many believe Bolin, more than the panel's current leading lights, deserved the Nobel prize that it won last month. Bert Bolin was born in Nykoping, Sweden, in 1925. An early academic high-flier, he swiftly joined a long tradition of world-renowned Swedish meteorologists. In the 1950s, he had already earned a reputation as a pioneer in using computers to predict the weather. But by the end of the decade he had found his true role by being one of the first scientists to recognise the importance to future climate of new findings about rising concentrations of carbon dioxide in the atmosphere. -

Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -

A Possible Albian Impact Crater at Murshid, Southern Oman
GeoArabia, Vol. 7, No. 4, 2002 Gulf PetroLink, Bahrain A possible Albian impact crater at Murshid, southern Oman Bruce Levell1, Pascal Richard2 and Folco Hoogendijk2, Petroleum Development Oman ABSTRACT During interpretation of a 3-D seismic survey in southern Oman a solitary, 2.5-km-wide circular basin with a central peak and raised rim was identified in the subsurface 35 km west of the Marmul oil field. The feature is the only one of its kind in the area. The basinal structure is probably of Late Cretaceous (Albian) age and the regional geology strongly suggests that it is neither a volcanic crater nor related to salt-dome tectonics or salt dissolution. It possibly represents a crater formed by a terrestrial impact event and has been named the Murshid crater. This report does not constitute a detailed investigation of the possible impact crater but rather records the 3-D seismic observations and the drilling that has taken place near the structure so far. INTRODUCTION During interpretation of a newly acquired 3-D seismic survey for oil exploration in southern Oman, a solitary 2.5-km-diameter circular basinal feature was identified as a possible impact structure and was named the Murshid crater. It lies 35 km west of the Marmul oil field in the South Oman Salt Basin (Figure 1). The center of the structure is at latitude 18º10’59"N, longitude 54º55’08”E, and it is buried at a depth of approximately 380 m below mean sea level (680 m below the ground surface). The authors are petroleum geologists who felt that the Murshid basinal structure needed reporting to the wider scientific community. -
