10ADCP is an instrument used to measure water currents in oceans, rivers and other bodies of water, using the principle of Doppler shift to calculate speed and direction of currents at different depths.
Explore
11An Optical Backscatter Sensor measures the concentration of suspended particles in water, used widely in environmental monitoring and water quality research.
Explore
12An effective, economical way to get an accurate picture of water quality within a specific spatial area, monitoring harmful algal blooms, dissolved oxygen, pH and turbidity.
Explore
15Water sampling and analysis for organic contaminants and inorganic water chemistry, characterising contaminant load at selected wells and inflow points.
Explore
16An in-situ testing method used to evaluate geotechnical properties, widely applied in marine engineering surveys — platform CPT, seabed CPT and down-hole CPT.
