Invited Speakers
Hans Slabbekoorn

 

Hans Slabbekoorn did his BSc and MSc at Utrecht University on animal behaviour and plant ecology. He received his PhD-degree at Leiden University in 1998 for studies on acoustic communication and auditory perception in free-ranging birds. He went to San Francisco, for a four-year post-doc and returned to Leiden University for another three-year post-doc, to become assistant professor in 2004, associate professor in 2012, and full professor in 2022. His interests range from animal signal evolution and environmental selection pressures to anthropogenic noise pollution and potential effects on birds, marine mammals, fish, and aquatic invertebrates.

Hanne Sagen

 

Hanne Sagen is Research leader at the Nansen Environmental and Remote Sensing Center. Norway. Her background is applied mathematics and ocean acoustics.  She has led many national and international projects to develop a regional multipurpose mooring network in the Fram Strait  nd in the central Arctic for acoustic thermometry and to pilot underwater acoustic GPS, working with researchers, industry and other agencies.  The beginning was a two mooring system in the Fram Strait in 2008-2009 followed by increasingly complex systems. In 2019, a yearlong pan-Arctic Coordinated Arctic Acoustic Thermometry Experiment (CAATEX)t was carried out with funding from Norway and the USA. Acoustic and oceanographic time series were obtained and have been used since to evaluate the capability of climate models to estimate the mean ocean temperature and to compare with acoustic measurements in 1994 and 1999. CAATEX is the forerunner of a Pan Arctic Multipurpose Mooring Network which includes ice-ocean measurements in combination with acoustic  thermometry, underwater geopositioning, and ocean sound  measurements.. This development is now in progress in the EU funded High Arctic Ocean Observation System (HiAOOS 2023-2027).

A B Wood Medal
Dr. David Barclay

 

Dr. David Barclay is an associate professor and the Canada Research Chair in Ocean Technology Systems in the Department of Oceanography, Dalhousie University. He received a Ph.D. in 2011 from the Scripps Institution of Oceanography, UC San Diego. His research asks what can be learnt by listening to the ocean. He has made recordings on the bottom of the Mariana Trench, the length of the Mississippi River, under the Canadian Arctic Ice, among the hydrothermal vents of the North Pacific, and in the tidal passages of the Bay of Fundy. He is an associate editor at the Journal of the Acoustical Society of America – Express Letters and IEEE Journal of Oceanic Engineering. In 2023 he received the Medwin Prize from the Acoustical Society of America.

H. Özkan Sertlek

 

H. Özkan Sertlek received his PhD degrees in underwater sound mapping from the University of Leiden, The Netherlands, in 2016, and in time-domain pulse propagation from Gebze Technical University in 2019. Between 2006 and 2011, he worked as a Senior Researcher at the Scientific and Technological Research Council of Turkey (TÜBİTAK). In the summer of 2009, he worked as a Visiting Researcher at the NATO Undersea Research Center. He was a Postdoctoral Researcher with the Delphi Consortium between 2016 and 2019, and in the Offshore Engineering section of the Hydraulic Engineering department between 2019 and 2022 at Delft University of Technology, The Netherlands. His scientific interests include underwater acoustic propagation methods, sound source modeling (including seismic airguns, pile driving, explosions), and sound mapping. The models he developed for acoustic propagation based on hybrid-mode flux theory (SOPRANO) and airgun source signatures (AGORA) are shared as open-source software and used in various international workshops and projects. Currently, he is a Senior Scientist with JASCO Applied Science Deutschland, where he actively contributes to various underwater acoustics projects.
