Tide Gauges

Sea level is a critical variable of our environment and has a high impact on coastal populations. Tide gauges are an important tool to determine trends in mean sea level, extreme conditions (and their relation to climate change), tidal computation, geodetic applications, harbour operations and navigation, as well as sea level hazards warning systems (tsunamis and storm surges).

Recognizing this critical and increasing need of tide gauge data, EuroGOOS Tide Gauge Task Team is bringing together the tide gauge communities in the European and adjacent seas. The EuroGOOS Tide Gauge Task Team compiles information on existing sea level networks, advises operators and scientists, and supports national and regional sea level initiatives towards enhanced and sustained system.

EuroGOOS Tide Gauge Task Team is a European network of tide gauge platforms. The Task Team assists its members with operational requirements, such as standardization of tide gauge operations, data and applications of multi-purpose networks, based on the Global Sea-level Observing System (GLOSS) and the requirements set by the Intergovernmental Coordination Group for the Tsunami Early Warning and Mitigation System in the North-eastern Atlantic, the Mediterranean and connected seas (ICG/NEAMTWS). It sets out a framework for collation of a single database describing the in-situ monitoring equipment and its status across Europe. Task Team members share success stories and discuss common challenges, including analysis of the funding strategies and importance placed on this work in the different countries.

The EuroGOOS Tide Gauge Task Team works to:

  • Promote the integration of tide gauges in European initiatives and identify relevant products required by sea-level data users;
  • Link national agencies of tide gauge operators with data providers acting as the European component in GLOSS;
  • Promote research and tests of new sea-level monitoring technologies;
  • Promote the recovery of historical data and related studies;
  • Contribute to the development of the European Ocean Observing System (EOOS) with the identification of duplication and/or gaps in the geographical coverage and in the existing sea level data portals in Europe.

At the operational level, the Tide Gauge Task Team:

  • Acknowledge existing data portals and ensure data availability according to the different  applications;
  • Promote the co-localisation and use of additional instrumentation relevant for sea level applications such as ocean bottom pressure sensors, land movement monitoring stations (GNSS), atmospheric parameters, and tsunami sensors;
  • Ensure the implementation of new requirements on sea-level quality control and data processing;
  • Provide recommendations (from operators to end-users) on data requirements and interoperability, quality control, complementary instrumentation (through interaction with other groups, e.g.  GNSS).
