Marine Environment Sensing Network (MESN)

Climate change, coastal urbanization and other anthropogenic impacts can disrupt marine environmental cycles, and cause far-reaching changes and re-organization of biological, physical and chemical systems. We aim to lay the

Reefwatch: Using soundscape to monitor reef health

While physical parameters (e.g. currents, temperature, water quality, visibility, salinity, etc) of the environment around coral reefs are relatively easy to measure with instruments, biological parameters (e.g. percentage of coral

glacier acoustics

Listening to glaciers

The Arctic is one of the focal points of global climate change, with surface temperatures rising twice as fast as the rest of the world. A significant component of the

Impact of bubbles on communication

It has long been known that bubbles severely affect underwater acoustic propagation. Communication systems operating in the surf zone or in areas with strong winds are strongly impacted by attenuation

bioacoustics

ASPOD: Acoustic Source Position Overlay Device

Sound is one of the most important modes of communication for animals living in the ocean since light only travels for several tens of meters (if the visibility is good)

Unet: The underwater networks project

The underwater networks project (Unet) develops technologies to extend communication networks underwater. Our work on near-optimal signal processing in snapping shrimp noise led to the development of the first Unet

bioacoustics

Dolphin crossmodal matching

Dolphins possess echolocation – a sense that humans don’t have – and although we can invent devices like sonar that mimics that ability, our understanding of what information about their
