Light Weight Array Technologies for Underwater Applications
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
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.
Abyss: A data driven approach to deepsea nodule exploration
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
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
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.
Underwater acoustic monitoring of marine megafauna in noisy coastal waters
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
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
Smart Water and Adaptive Technologies for Big Data collection
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
Articles from Affiliated Sites
The featured articles here come from affiliated sites like the Unet, Subnero and Earthzine.
Unet project has its origins in the ARL way back in 2004.The core technology called UnetStack, is an agent-based network stack that allows underwater network to be rapidly developed, tested and deployed. Unet has offered much of its technology as free open-source software to promote community collaboration, and continues today to advance its research and development of the technology.

@CommsEng Research published from our lab recently describes sonar imaging of the acoustic info in dolphin sonar clicks for the 1st time using a signal processing tool. It uses prior information on the targets - their sparsity, I.e. they occupy a small fraction of the volume searched in.
