ECO Supplies and Instals Monitoring Buoys

ECO Environmental recently installed 3 buoy-mounted water quality monitoring sondes to monitor the potential impact of construction works in the Cocos Islands. The Australian government is extending the airport runway and there is a need to monitor the health of the local seagrass during the construction period.

ECO Environmental supplied, calibrated and installed three YSI EXO sondes with integrated buoy systems including remote data access and solar power.  In addition to the usual parameters of pH, EC and DO, the sondes also measure turbidity as well as having a separate but fully integrated PAR sensor.

ECO led the installation of the buoys and sondes onsite.  One of ECO’s trained technicians, Asher Pettitt, travelled to Cocos Islands to assemble the systems and undertake onsite diagnostics and testing prior to the installation, including data configuration changes onsite.
