Significance of sound in aquatic environments covers marine organisms' use of sound for communication, navigation, and foraging, as well as the impacts of human-induced noise pollution. Efforts focus on mitigating adverse effects and preserving marine acoustic habitats.

• Fine-scale spatial variability of marine soundscape corresponds with habitat utilization of Indo-Pacific humpback dolphins in Hong Kong waters
• Passive acoustic monitoring in western and southern Hong Kong waters
• Night-time acoustic line transect for dolphin and porpoise detection and localization

Distribution and impact processes of microplastic particles in marine environments and organisms. It highlights how these particles are ingested by marine life, leading to ecological risks such as potential harm to marine species and disruptions to food webs.

Studied animals and environemnts include: Indo-Pacific humpback dolphins; Green-lipped mussel; Oysters; Human faeces; Jellyfish; Sponge in Deep Artic; Brine shrimp in Tibet plateau; Hong Kong's river and marine water; Hong Kong's road runoff

Other microplastic related projects:

• Holographic imaging technique for in situ microplastic identification

  

• Microbiome community on microplastic particles in river water (In submission)

• Development of nano-bubble for removal of sub-10 micron microplastics in waste water
