David Barclay is an Associate Professor and Graduate Coordinator in the Department of Oceanography at Dalhousie University's Faculty of Science. His research focuses on acoustical oceanography, physical oceanography, and environmental monitoring, with specialties in ambient noise analysis, hydrothermal vent dynamics, and underwater instrumentation. He leads a lab exploring the acoustic properties of marine environments, including Arctic regions, deep-sea trenches, and hydrothermal vent fields. His work integrates field measurements, numerical modeling, and sensor development to address challenges in ocean health, climate change, and marine conservation.
Barclay's research topics include sediment acoustics, oceanographic instrumentation, and the impact of anthropogenic noise on marine life. He has contributed to projects such as passive acoustic monitoring of North Atlantic right whales, real-time Arctic soundscapes, and the development of autonomous underwater vehicles for bathymetric surveys. His laboratory website provides access to acoustic datasets and tools for environmental acoustic analysis.
Key research trends in his publications (2022–2025) emphasize the application of acoustics to measure ocean acidity, track vessel noise, and study hydrothermal vent soundscapes. He has also explored the effects of environmental changes, such as reduced shipping noise during the 2020 pandemic, on marine ecosystems. His work bridges engineering, physics, and biology to advance sustainable ocean management practices.
Notably, Barclay coordinates graduate programs in oceanography, fostering interdisciplinary training in marine acoustics and environmental science. His lab collaborates with organizations like Ocean Networks Canada to deploy cabled observatories and conduct long-term acoustic monitoring in the Northeast Pacific. Current initiatives include developing autonomous hovercraft for shallow-water surveys and improving geoacoustic inversion techniques for seabed characterization.
