Applications of Paleoenvironmental Techniques in Estuarine Studies

Dr. Kaarina Weckström is a Senior Researcher at the Geological Survey of Denmark and Greenland and an Adjunct Professor at the Department of Environmental Sciences, University of Helsinki. Her research focuses on the reconstruction of past climate and environments using sediment proxy records. She has a special interest in proxy evaluation and development. Dr Krystyna Saunders is a Senior Research Scientist at the Australian Nuclear Science and Technology Organisation. She specializes in the study of past climates and ecosystems using lake and estuarine sediments. Peter Gell is Professor of Environmental Science at the Water Research Network, Faculty of Science and Technology, Federation University Australia. His research interests include short term palaeoecology to establish environmental baselines; wetland and stream water quality biomonitoring; climate change and its impact on water as a natural resource, and diatoms and birds as indicators of ecosystem health. Greg Skilbeck is a sedimentary geologist and geological oceanographer with over twenty five years of experience in the collection and interpretation of palaeoenvironmental and palaeoclimatic data from sediment cores.  He has participated in several oceanographic research cruises including two ODP Legs.  Dr Skilbeck has been at the University of Technology Sydney since 1987 and is currently Professor of Earth Sciences in the School of Life Sciences.
