The Inishmore Tide gauge is part of the Irish National Tide Gauge Network which is a network of tide gauges located around the coast of Ireland collecting water level data as part of the development of a permanent tidal monitoring infrastructure. Parameters collected include; Station (ID), DateTime (yyyy-mm-ddThh:mm:ss), Water Level (Sea Level above Lowest Astronomical Tide [LAT], m) and Water Level (Water Level wrt Ordnance Datum Malin Head, m), sea surface temperature (celsius), and Pressure (measured variable) exerted by the atmosphere (MB). The Inishmore Tide gauge (53.1178, -9.6669) is owned and maintained by the Marine Institute and has been operational since April 2007. The Inishmore Tide gauge is part of the Irish National Tide Gauge Network which provides real-time data and freely available tidal predictions to operational activities (flood forecasting and monitoring) supporting research, recreational and navigation activities.
