The Irish National Tide Gauge Network (INTGN) is managed by the Marine Research Infrastructures team. The purpose is to monitor the water level and the tidal harmonic of the Republic of Ireland's coastline (Tidal flows around Ireland) and to provide tidal predictions and free for public use. Currently, the INTGN consists of 19 tide gauge monitoring nodes that measure real-time data for actual water level and tide predictions (Tidal Predictions). The main sensor at each node is an OTT Contact Bubbler Sensor (CBS) with a data logger. Some nodes also measure sea temperature and air pressure parameters. The data is transmitted via telemetry to provide real-time measurements every 5 minutes and is available to view and download at Tidal Observations. The tidal predictions and real time monitoring provide critical information for flood forecasting and for supporting research, coastal engineering, recreation and navigation activities.
The INTGN also supports 7 river monitoring stations at the MI Newport Research Facility.
Global Sea Level Observing System (GLOSS)
In 2020, two pre-operational Global Sea Level Observing System (GLOSS) were installed at Howth Harbour, Dublin and Union Hall Harbour, Cork to monitor sea level and are managed by the Marine Research Infrastructures team. These gauges provide accurate sea level measurements and are equipped with 3 sensors (OTT CBS) and 1 co-located Global Navigation Satellite System (GNSS).
