Correspondence and select subject files of Scripps Institution of Oceanography micropaleontologist William R. Riedel, including JOIDES Planning Committee files related to the Deep Sea Drilling Project.

William Rex Riedel (b. 1927) is a micropaleontologist from Tanunda, South Australia. He was educated at the University of Adelaide, where he received his B.Sc. (1947), M.Sc. (1952) and D.Sc. (1976). Riedel began his decades-long career at the Scripps Institution of Oceanography (SIO) in 1951 as a graduate research geologist. He was appointed Senior Lecturer in 1981. Riedel is distinguished for his work on taxonomy and stratigraphy of Radiolaria and marine sediments. He participated in many SIO expeditions, including Northern Holiday (1951) and the Argentine Antarctic Expedition (1956-57). Riedel's work on stratigraphy and on the analysis of sediment cores was especially important to the Deep Sea Drilling Program (DSDP). He was active on the JOIDES Planning Committee, and later served as chair of the SIO Geological Research Division from 1978-1983. Riedel was named curator of DSDP cores and served on the JOIDES Information Handling Panel beginning in 1990. He was a founder of EURORAD (later INTERRAD), the international community of radiolarian workers. Riedel retired in 2001.


The collection contains the correspondence and select subject files of micropaleontologist William R. Riedel, including JOIDES Planning Committee files related to the Deep Sea Drilling Project.
