Monitoring and Characterization of Marine Organisms for Underwater Surveillance (MCMOUS)
The ocean is filled with the distinctive crackling sounds of snapping shrimp, one of the most dominant noise sources in Singapore’s coastal waters. These highly
Shallow-water Profiling Device (SPD)
Real-time, in-situ observations are essential to “ground truth”, correct for model biases, fill gaps, and provide accurate inputs for forecasting models in fast-changing marine environments.
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
In polar regions, a large component of the ice loss that feeds sea level rise occurs due to two mechanisms – calving and submarine melting at the glacier-ocean
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
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.
