Jörg Imberger is the Director of the Centre for Water Research and Professor of Environmental Engineering at the University of Western Australia (UWA), where he is a Vice-Chancellor's Distinguished Fellow. Imberger received his PhD at the University of California, Berkeley in 1970 and became Professor of Environmental Engineering at UWA in 1979. Clelia Marti is research assistant professor at the Centre for Water Research at the University of Western Australia (UWA). She is a field-oriented Physical Limnologist and provides scientific leadership to real time field investigation in aquatic environments. Her research interests lie in transport and mixing processes in lakes, rivers, estuaries and coastal seas. She has made substantial contribution to the understanding of the benthic boundary layer in stratified lakes and its central role in setting up a volume flux that is responsible for transporting nutrient rich water from the deepest part of the lake into the thermocline where it becomes available for primary production in the surface layer. She has conducted field work in a number of sites around the world including Lake Kinneret (Israel), Thomson Reservoir (Australia), Cockburn Sound (Australia), Lake Valle de Bravo (Mexico), Setubal Lagoon (Argentina), Parana River (Argentina), Lake Coeur d'Alene (USA), and Lake Constance (Germany).
