Global Sea Level Observing System (GLOSS) Stations on the Irish National Tide Gauge Network (INTGN)
The INTGN is a network of permanent, managed tide gauges located around the Irish coast, collecting water level data to constitute the development of the permanent tidal monitoring infrastructure. The Marine Institute owns the network and is responsible for the service, maintenance, and quality control of all the network nodes. The network is funded by the Department of Agriculture, Food and the Marine.
Two of these nodes have been developed to become part of the Global Sea Level Observing System (GLOSS) ( https://gloss-sealevel.org/sea-level-applications; https://uhslc.soest.hawaii.edu/gloss/), which provides enhanced quality sea-level monitoring at chosen sites where water level and land level observations are co-located. As a GLOSS requirement, there are three gauges running side by side t each site. Two primary gauges (100% redundancy) and a third ‘B-Gauge’, that for calibration purposes only measures from Mean Sea Level (MSL) and above. The Marine Institute have instigated, designed, implemented and funded these two stations throughout. The GLOSS gauges are maintained, calibrated and characterised on a six-monthly rolling cycle and receive an annual classic land level survey to check wider area substrate stability. GNSS data are collected by the co-located, state of the art CGPS system. The Marine Institute manage the water level and land survey data, where the GNSS data are reported directly to SONEL ( https://www.sonel.org/) from each site. The OPW operate the nation’s third GLOSS station at Portmore Pier, Malin Head.
- Howth Harbour GLOSS station came online in November 2018 and its Data Catalogue can be found at: https://data.marine.ie/geonetwork/srv/eng/catalog.search#/metadata/ie.marine.data:dataset.4780
- Union Hall Harbour GLOSS station came onstream in November 2020 and can be found at: https://data.marine.ie/geonetwork/srv/eng/catalog.search#/metadata/ie.marine.data:dataset.5403

Data access:
Data is available via the Marine Institute’s ERDDAP download portal: https://erddap.marine.ie/erddap/tabledap/IrishNationalTideGaugeNetwork.html Below are some examples of how a user can customise a download from ERDDAP :
– Filter data by quality flag
– Select specific gauges
– Choose date ranges
– Specify file output formats
Real-time data is also accessible from an SFTP site associated with www.irishtides.ie. Please get in touch for information on accessing the SFTP site.
