Biographical details

Dr Phil Mulhearn obtained his PhD degree in turbulent fluid mechanics from University of Sydney in 1973. He was a Principal Research Scientist in the Defence Science & Technology Organisation (DSTO) and was with DSTO from 1977 to 2004. He worked on the physical oceanography of the East Australian Current and Tasman Front, uses of satellite remote sensing in oceanography, acoustic seabed classification, and mine burial processes.

He was a member of a NATO Specialist Team ¿ Mine Burial Analysis, and was involved in Specialist Teams on Mine Burial and on Environmental Reconnaissance of The Technical Cooperation Programme (TTCP). He has been a recipient of TTCP Achievement Award. (TTCP is an organisation for defence research collaboration between USA, UK, Canada, Australia and New Zealand). Since his retirement from DSTO in 2004 he has been, at University of Sydney, an Adjunct Associate Professor in School of Civil Engineering and an Honorary Associate in School of Geosciences. Here in the past he has worked on ocean colour remote sensing of coastal seas, and acoustic surveying for remains of Zheng He¿s fleets (a joint Australian ¿ Chinese project). He has an ongoing interest in Australian-Chinese scientific collaboration.

Research interests

Phil¿s current research covers several strands. Sydney Harbour and adjacent bays have been severely impacted by human activities and he is researching the bathymetric changes which have occurred as a result. These changes have been principally due to dredging and to increased sedimentation caused by land use changes. Charts exist from as early as 1788, and are certainly useful for quantitative purposes from the mid 19th Century.

He is also involved in SHED (Sydney Harbour Environmental Data Facility) project to model real-time environment conditions in the Harbour and to monitor coincident environmental measurements. The plan is to display results on the Internet. Linked to this is an interest in modelling other aspects such as the dispersion of pollutants from incidents such as chemical spills from ships or industrial sites.
