Tim Sullivan and Dian Zhang of MESTECH recently deployed a Chelsea Technologies Group hydrocarbon sensor on a trial basis in the Lower Liffey Estuary. This sensor is designed for shallower depths (

The project will expand with the deployment of a passive sampler at the mouth of the river to determine the composition of hydrocarbon compounds within the water column. At present the sensor is available on a trial basis from CTG, and data is logged locally using a Raspberry Pi and is not being made available in real-time during the current phase of the deployment

Chelsea Technologies has a range of water quality monitoring sensors specifically designed for hydrocarbon monitoring.
