Scott received his Ph.D. (dissertation, 1990) and M.S. (thesis, 1985) in geology from The Ohio State University. He spent one year at the Byrd Polar Research Center investigating Holocene climatic and oceanographic variability in the Antarctic Peninsula region of Antarctica. In 1992, Dr. Ishman came to the USGS where he was part of the Pliocene Research, Interpretation and Synoptic Mapping (PRISM) program investigating deep sea paleoceanographic change related to global warming. In addition, he has investigated Arctic Plio-Pleistocene paleoclimatic and paleoceanographic evolution. Dr. Ishman's research interests are in benthic foraminiferal paleobiology, and statistical applications of foraminiferal data to paleoclimatic, paleoceanographic and paleoecologic problems. Scott is currently working on the ecosystem history of the south Florida region. He is also funded by the National Science Foundation investigating the Holocene paleoclimatic history of the Bellingshausen Sea margin of the Antarctic Peninsula.
Dr. Ishman's current research is focused on the reconstruction of the ecosystem history of south Florida with regard to salinity, dissolved oxygen, nutrient input, substrate mobility and sea level.
