In general, these records will contain many jumps that make them unsuitable for time series analysis. Monthly mean, surge and extreme values are also available for some or all of this period. Tide gauges, which provide us with data going back more than a century in some places, measure local or relative sea level by tracking water levels compared to the adjacent land. Therefore, tide gauge data is valuable information to a wide range of activities over a variety of timescales, for scientific research as well as for many practical applications. View up-to-date tide gauge records and other archived Scientists use two main tools to track sea level changes: tide gauges and satellites. ncCF - Download a NetCDF-3 CF Discrete Sampling Geometries file (Contiguous Ragged Array). This data is critical for many coastal activities, including safe navigation, sound engineering, and habitat restoration and preservation. The data sets analyzed are relative to the Revised Local Reference (RLR) datums as established by PSMSL (approximately 7 meters below mean sea level). . The information on government servers are in the public domain, unless specifically annotated otherwise, and may be used freely by the public. 2 days ago · Tide gauge is a device for measuring sea level changes and detecting tsunamis. The API data is normally updated every 15 mins so typically the latest available reading will lag between 15 and 30 The data for these stations were obtained from the Permanent Service for Mean Sea Level (PSMSL), a data bank for sea level information from the global network of tide gauges. Compared to satellite data, tide gauge data offer a longer record and finer temporal resolution but coarser spatial resolution. , 2013; PSMSL, 2018] show that ". Access to the UK Tide Gauge Network data holdings maintained at the British Oceanographic Data Centre (BODC). SEA LEVEL MONITORING The Global Sea Level Observing System (GLOSS) is a network of tide gauges around the world that was established to monitor the global sea level change. Browse data from the UK National Tide Gauge Network, owned and operated by the Environment Agency, on behalf of the UK Coastal Flood Forecasting service (a partnership between the Environment Agency, Natural Resources Wales, the Scottish Environment Protection Agency and Northern Ireland Department for Infrastructure - Rivers). Tidal data is used for the predictions at 9 tidal stations and 6 tidal stream stations. Access near-realtime raw sea level data from the British Oceanographic Data Centre from the UK Tide Gauge Network. To estimate the tide times at Erith, find the midpoint between the tides at Silvertown and Tilbury gauges. This tide gauge data set is the largest ever to have been assembled. A Unless otherwise stated, the Tide Gauge Metadata Sheets are as supplied by the tide gauge owners, with additional comments added by the National Tidal Centre, where appropriate. About Observed Monthly Sea Levels and Statistics The Monthly Sea Levels and Statistics are based on hourly sea level observations. Obtaining Tide Gauge Data Referencing PSMSL data When using the tide gauge data set from the PSMSL, we ask that you reference the last paper describing the data set, as well as the data set itself. Oct 1, 2022 · The National Oceanic and Atmospheric Administration (NOAA) Center for Operational Oceanographic Products and Services (CO-OPS) operates and maintains the National Water Level Observation Network (NWLON) consisting of 210 long-term, continuously operating water level stations on all U. , 2013; PSMSL, 2016]. Sea Levels. S. For Observed Monthly Sea Levels and Statistics, please click on Table and Plot under Sea Level in the table below. . Search Historic Tide Gauge Records Search Digital Data by Search Digital Data by Access Data via THREDDS Data Server High-resolution DART® Data NOS/CO-OPS Tide Station Metadata Inundation Grids Global Tsunami Database Water Level Media Fact Sheet NCEI is the long-term archive for all NOAA coastal tide gauge data: 1-minute water level data from the NOAA/National Ocean Service (NOS) Center for Operational Oceanographic Products and Services (CO-OPS) and high-resolution (10-second or 15-second) water level data from the Pacific Tsunami Warning Center (PTWC) and the National Tsunami Warning Center (NTWC). The Erith tidal gauge is currently offline. Leaflet | Powered by Esri | Sources: Esri, TomTom, Garmin, FAO, NOAA, USGS, © OpenStreetMap contributors, and the GIS User Community The data prior to 2016 was provided at hourly intervals, so this data has been interpolated by Maritime Safety Queensland in order to ensure all the data is at 10 minute intervals. See our referencing recommendation for more information. Dec 11, 2025 · Tide gauge data are used to validate ocean models and to detect errors and drifts in satellite altimetry. These predictions are published in the Singapore Tide Tables. The tide gauges are located on piers around the coastline of the Republic of Ireland.
