The availability of low power and miniature electronic components and sensors have made it possible to build arrays of smaller diameter and lightweight compared to traditional bulky and heavy arrays.
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
ARL’s foray into deepwater exploration was conducted as part of the Keppel-NUS corporate laboratory program to carry out exploration works for polymetallic nodules in the Clarion Clipperton Zone of the
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
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
Dolphins and dugongs constitute some of the megafauna presence in Singapore waters. However, our baseline understanding of the local population such as their visiting patterns and foraging behavior, are insufficient
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
Understanding spatiotemporal variation of water quality is a crucial but challenging task. We turn to big-data collection and use adaptive-path-planning, sampling algorithms and novel drifting sensors.Urban water bodies are complex
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)
The long propagation delay due to slow speed of sounds in water (as compared to speed of electromagnetic waves in air) has often been “blamed” for poor performance of network
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
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
