Triskel Marine’s DataBuoy is a cost effective way of monitoring numerous environmental parameters in real time. The buoy is tough, easily deployed, light weight and completely autonomous with multiple inputs to support a wide range of different sensors. It can be configured for use in water as shallow as 0.5m, allowing transient events in both marginal and deep water environments to be recorded and viewed as they happen.

GPRS technology is used to upload data directly to a password protected, user web site at intervals configurable from 10 minutes to 24 hours. Communication with the buoy is bidirectional and factors such as update frequency, alarm levels and calibration factors can all be set from the web site without the need to go afloat.

If a threshold is breached, notifications can be sent automatically to named users by email or text message.

There is no limit to the number of buoys that can be deployed simultaneously and each is individually addressable from the web site. All buoys are fitted with GPS, battery monitoring and solar panels as standard, with weather reporting, on board data logging and navigation lights available as an option. For areas with poor, or no, mobile phone coverage other available communication methods include GSM, text messaging and radio transmission.

Typical applications include:

• Dredging - buoys can be used as sentinels to monitor turbidity at key positions and to alert port and dredging authorities by text message or email as soon as limits are exceeded

• Aquaculture and environmental surveying - for establishing baseline data, monitoring transient events and safeguarding aquaculture sites in real time

• Sediment transport surveys - when fitted with a calibrated turbidity sensor, sediment mass can be determined at various stations, allowing deposition rates and positions to be calculated aquaculture sites in real time
