The Society for Sedimentary Geology is an international not-for-profit, scientific society based in the US state of Oklahoma. It is commonly referred to by its acronym SEPM, which refers to its former name, the Society of Economic Paleontologists and Mineralogists.
The society's reason for being is to disseminate scientific information on sedimentology, stratigraphy, paleontology, environmental sciences, marine geology, hydrogeology, and related specialties. Members benefit from both gaining and exchanging information pertinent to their geologic specialties. Information is dispersed via the publication of two major scientific journals, the Journal of Sedimentary Research (JSR) and PALAIOS , and the organization of technical conferences and short courses. It also publishes a monthly magazine for its members, The Sedimentary Record, which is now a diamond open access journal.
The society arranges research conferences based on topics that are relevant to members and show promise of progress. They are meant to focus the attention of specialists with diverse expertise on some theme of mutual interest and stimulate new research areas or approaches. They are designed to encourage summaries of new, incomplete research, and invite open speculation. Field trips, poster sessions, core workshops, and laboratory experiments are often included as part of a conference.
Annually the society recognizes people who have contributed to the various areas of sedimentary geology. The awardees are nominated by members of the society, but do not have to be members themselves. These medals are named in recognition of outstanding geologists.
The society also bestows, at its discretion, honorary membership and a distinguished service award to society members.
Kenneth Jinghwa Hsu Ph.D., M.A., born 28 June 1929, is a Chinese scientist, geologist, paleoclimatologist, oceanographer, government advisor, author, inventor and entrepreneur who was born in Nanjing, China.
William Christian Krumbein was a notable geologist, after whom the Krumbein Medal of the International Association for Mathematical Geology (IAMG) was named. This medal was established at the 25th International Geological Congress in Sydney, in 1976. Krumbein was a founding officer of the IAMG.
Raymond Cecil Moore was an American geologist and paleontologist. He is known for his work on Paleozoic crinoids, bryozoans, and corals. Moore was a member of US Geological Survey from 1913 until 1949. In 1919 he became professor at the University of Kansas (Lawrence). In 1953 Professor Moore organized the launch and became the first editor of the still ongoing multi-volume work Treatise on Invertebrate Paleontology. Contributors to the Treatise have included the world's specialists in the field. He served as president of the Geological Society of America in 1958. In 1970 he was awarded the Mary Clark Thompson Medal from the National Academy of Sciences.
The Geological Association of Canada (GAC) is a learned society that promotes and develops the geological sciences in Canada. The organization holds conferences, meetings and exhibitions for the discussion of geological problems and the exchange of views in matters related to geology. It publishes various journals and collections of learned papers dealing with geology.
Gerard Viner Middleton FRSC, often known as Gerry Middleton, was a Canadian geologist and university teacher.
The William H. Twenhofel Medal is the highest award given by the Society for Sedimentary Geology (SEPM). It was instituted in memory of William H. Twenhofel and is awarded annually to a person for his or her "Outstanding Contributions to Sedimentary Geology."
Francis John Pettijohn was an American geologist who served for many years on the faculty of Johns Hopkins University.
Lawrence Alexander Hardie was an American geologist, sedimentologist, and geochemist.
Isabel Patricia Montañez is a paleoclimatologist specializing in geochemical records of ancient climate change. She is a distinguished professor and a Chancellor's Leadership Professor in the department of earth and planetary sciences at University of California, Davis. As of 2021, Montañez is the director of the UC Davis Institute of the Environment.
Frederick T. Mackenzie is an American sedimentary and global biogeochemist. Mackenzie applies experimental and field data coupled to a sound theoretical framework to the solution of geological, geochemical, and oceanographic problems at various time and space scales.
The Raymond C. Moore Medal for Paleontology is awarded by the Society for Sedimentary Geology to persons who have made significant contributions in the field which have promoted the science of stratigraphy by research in paleontology and evolution and the use of fossils for interpretations of paleoecology. The award is named after Professor Raymond C. Moore, the American paleontogist who helped to found the society.
Alfred R. Loeblich Jr (1914–1994) was an American micropaleontologist. He was married to Helen Niña Tappan Loeblich and the two co-authored a number of important works on the Foraminifera and related organisms.
Alfred George Fischer was a German-American geologist.
David L. Clark is a paleontologist. He was the W.H. Twenhofel Professor of Geology and Geophysics at the University of Wisconsin–Madison, Madison, Wisconsin.
William Winn Hay was an American geologist, marine geologist, micropaleontologist, paleoceanographer, and paleoclimatologist, primarily associated with the University of Colorado.
Kenneth Orris Emery (1914–1998) was a Canadian-born American marine geologist.
Pamela Hallock Muller is a scientist, oceanographer and professor at the University of South Florida in the College of Marine Science.
Nora Noffke is an American geologist who is a professor in the Department of Ocean and Earth Sciences, Old Dominion University in Norfolk, Virginia, USA. Noffke's research focuses on the sedimentology of biofilm forming sedimentary structures in modern aquatic environments, where clastic deposits dominate. Such structures occur in the fossil record as well. Her studies are interdisciplinary combining sedimentology with microbiology, geochemistry, and mineralogy.
William Henry Twenhofel was an American sedimentary geologist who wrote a landmark text Treatise on Sedimentation (1926) which went into more editions. He served for many years as a professor of geology at the University of Wisconsin. The Society of Economic Paleontologists and Mineralogists instituted the Twenhofel Medal in his memory.
