The Marine Geophysics Laboratory is research and development group at James Cook University. We specialise in physical oceanography and monitoring of sediment transport, and have been contracted for numerous commercial dredging projects. Novel oceanographic instruments are also designed and manufactured at the lab. Robust and proven over many field deployment, these instruments include nephelometers, river and ocean drifters, water samplers, and current meters.
Instruments:
Marotte HS
Version 2 of our drag-tilt current meter features an electronic compass, gigabytes of storage and high sampling rate.
River Drifter
The river drifter is a floating turbidity sensor that is deployed during flood events to measure changes in sediment input along a river.
Nephelometer
The Nephelometer measures sediment deposition, turbidity, photosynthetically available radiation (PAR), water depth, Root Mean Squared (RMS) water depth and water temperature. Telemetered or stand alone, this instrument is robust and powerful in baseline and impact assessment marine studies.
