Richard Arthur Reyment: Father of the International Association for Mathematical Geology

Richard Arthur Reyment was born of parents of English, Swedish, and Spanish descent in Coburg, Victoria, Australia on 4 December 1926. After obtaining his bachelor degree from Melbourne University in 1948 he spent several years with the British Colonial Service in Nigeria. While there he obtained his masters degree from Melbourne and a doctorate from the University of Stockholm (Sweden). His work in Nigeria led to the appointment as professor at the University of Ibadan. He returned to Sweden in 1965 with an appointment from the Swedish Natural Science Research Council. In 1967 he was awarded his DSc from Melbourne University and was appointed to the Chair of Historical Geology and Paleontology at the University of Uppsala (Sweden), where he remained until his retirement in 1991. His early studies on random events, multivariate morphometrics, and statistical analysis in geology and biology naturally led him into the quantitative aspects of his chosen profession, and whetted his desire to share these experiences with others with similar interests. This, he decided, could best be accomplished through an organization to promote quantitative methods and approaches, which led to his concept of the International Association for Mathematical Geology (IAMG). His efforts and enthusiasm resulted in the founding of the Association at the ill-fated International Geological Congress (IGC) in Prague in 1968. Reyment was elected the first IAMG secretary general and later the second president. The IAMG is affiliated with both the IGC and the International Statistical Institute (ISI). In recognition of his scientific accomplishments he was awarded IAMG's highest award, the William Christian Krumbein Medal, in 1979 and a special Certificate of Merit in 2002. Reyment's pioneering efforts have influenced a generation of geologists and paleontologists.

Climate change and the Viking-age fjord environment of the Eastern Settlement, South Greenland

NOTE: This article was published in a former series of GEUS Bulletin. Please use the original series name when citing this article, for example: Kuijpers, A., Abrahamsen, N., Hoffmann, G., Hühnerbach, V., Konradi, P., Kunzendorf, H., Mikkelsen, N., Thiede, J., & Weinrebe, W. (1999). Climate change and the Viking-age fjord environment of the Eastern Settlement, South Greenland. Geology of Greenland Survey Bulletin, 183, 61-67. https://doi.org/10.34194/ggub.v183.5206 _______________ The main objective of the project reported here is to reconstruct late Holocene hydrographic changes in South Greenland fjords and to study the relationship with large-scale atmospheric climate change; in particular to shed light on a possible link between these hydrographic changes and the disappearance of the Norse from Greenland more than five centuries ago. The project (1998–2000) is financially supported by the Danish Natural Science Research Council and the Government of Greenland.

Wandel Sea Basin: basin analysis – a summary

In 1991 a three year research project was initiated by the Geological Institute, University of Copenhagen with financial support from the Ministry of Energy, the Danish Natural Science Research Council and the Carlsberg Foundation. The 'Wandel Sea Basin: basin analysis' project was carried out in collaboration with the Geological Survey of Greenland and included field work in North Greenland; in eastern Peary Land in 1991 and Amdrup Land in 1993 (Fig. 1; Hakansson et al., 1994). The project is a continuation of earlier investigations in the Wandel Sea Basin carried out during geological mapping of North Greenland by the Geological Survey of Greenland in 1978–1980 and during later expeditions to the area (e.g. Hakansson, 1979; Hakansson et al., 1981, 1989, 1991, 1994). Hydrocarbon related studies of the Wandel Sea Basin were continued during the 1994 field season (Stemmerik et al., this report).

New observations of marine trace fossils in delta plain sequences, southern Nûgssuaq, West Greenland

During the 1988 field season new observations were made on the sediments of the Upper Cretaceous Atane Formation in southern Nûgssuaq. These observations indicate that the degree of bioturbation may be taken as an indicator of the degree of marine influence within the interdistributary delta plain environments. The field work was carried out during six days in July 1988 as part of a sedimentological research project supported by GGU and the Danish Natural Science Research Council.
