What is the ESEAS?

The European Sea-Level Service (ESEAS) is an international collaboration of organisations in 18 countries. These countries are operating more than 170 tide gauges along European coasts or providing sea level related information originating from other sources such as satellite altimetry, GPS and absolute gravity measurements at tide gauges.

What are the aims of the ESEAS?

What is the ESEAS-RI?

The ESEAS-RI (Research Infrastructure) project was established by the ESEAS to support the research infrastructure of the ESEAS and facilitate full scientific exploitation of European sea level observations. This project is supported by the European Commission.

The primary scientific objective of the ESEAS-RI project is to study sea level variations at inter-annual to century time scales as well as to assess potential future changes in mean sea level.

There are five work packages

  1. Quality control of sea level observations. Provide access to, and quality control European tide gauge data.
  2. Absolute sea level variations. The main objective is to correct relative sea level observations for vertical land movement, determined from continuous GPS measurements.
  3. Decadal to inter-decadal sea level variations. Provide a model of relative sea level variations over the last 100 years, with temporal resolution of 10 years.
  4. Improving the sea level observing system. The main objective is to enhance long-term research. This will be achieved through upgrading selected tide gauges in scientifically relevant locations to present standard and augmenting specific tide gauges with continuous GPS.
  5. Overall project management.

What is BODC’s role?

BODC is involved in work package 1 of the ESEAS-RI and we are working on
