CSA Produce Custom Portable OBS3 Measurement/Logging System for Gorgon Marine Monitoring

The Gorgon Marine Monitoring Program involves monitoring of turbidity at a number of locations near the dredging and construction operations. A network of nine remote monitoring sites utilise the Campbell Scientific Australia (CSA) OBS3 turbidity sensors mated to a custom-built satellite telemetry system (not provided by CSA). The RPS/SKM Marine Monitoring Alliance required a portable turbidity measurement and logging system that could be used in the field for geo-referenced spot measurements of the turbidity plumes as well as laboratory use for cross-calibrating other turbidity measuring devices. Given that the design and measuring geometry of turbidity sensors are not consistent across different manufacturers, we required a system that used the OBS3 sensor so that measurements were consistent with the remote monitoring network.

Campbell Scientific Australia (CSA) were able to custom make a portable system that met our field-based requirements (waterproof, GPS enabled, display and logging). The system was professionally finished, came pre-configured and also had detailed instructions on how to further setup the logger. The response from CSA was prompt and professional and we’d be happy to approach CSA with our custom requirements in future.
