Christine Erbe holds an M.Sc. degree in Physics (University of Dortmund, Germany) and a Ph.D. in Geophysics (University of British Columbia, Canada). She worked as a Research Scientist at Fisheries and Oceans Canada, was Director of JASCO Applied Sciences Australia, and eventually returned to academia, where she is now Director of the Centre for Marine Science and Technology at Curtin University (Perth, WA, Australia) and Director of the Centre of Ocean and Earth Science and Technology at Curtin University (Moka, Mauritius). Christine's interests are underwater sound (biotic, abiotic, and anthropogenic), sound propagation, signal processing, and noise effects on marine fauna. She's a John Curtin Distinguished Professor, Fellow of the Acoustical Society of America, Board member of the International Commission for Acoustics, former member of the ISO Technical Subcommittee on Underwater Acoustics, former Chair of the Animal Bioacoustics Technical Committee of the Acoustical Society of America, and former Chair of the international conference series on The Effects of Noise on Aquatic Life.

Jeanette A. Thomas obtained her Ph.D. in Ecology and Evolutionary Biology from the University of Minnesota (1979) on underwater vocalizations of Weddell seals in the Antarctic. She was Director of the Bioacoustics Laboratory at Hubbs-Sea World Research Institute (San Diego, CA, USA), a Senior Scientist at the Naval Ocean Systems Center (Kailua, HI, USA), and Professor in Biology at Western Illinois University (WIU; Macomb, IL, USA), where she helped established a Master's degree program in Biology in collaboration with Shedd Aquarium (Chicago, IL, USA). In 2000, she developed the WIU Graduate Certificate in Zoo and Aquarium Studies. Jeanette received several awards through WIU: Distinguished Faculty Lecturer, Outstanding Researcher, and Distinguished Alumni. Jeanette was President of The Society for Marine Mammalogy (1994-1996) and Editor for Aquatic Mammals (2000-2009).
