The consortium consists of 21 partners from 12 countries. The consortium includes national authorities responsible for tide gauge operation and/or the geodetic control of tide gauges as well as research institutes involved in research and operational activities related to sea level. Additonally, through the ESEAS, the consortium is closely linked with the national authorities for tide gauge operation in additional 8 countries as well as the scientific experties provided by the ESEAS Technical Committee.


Roles of the partners

The partners and their roles in the project are summarised in the table below. Each partner has a high international reputation for expertise relevant to the specific roles. The consortium is interdisciplinary and brings in particular together the traditional field of sea level observation and the new geodetic techniques required for the measurement of absolute sea level variations. Another complementarity are the experts in satellite altimetry, which are brought together with sea level scientists having long-standing experience in the analysis oand interpretation of tide gauge records.

In particular, the following specific expertise is emphasised:

• P3, P5, P6, P8, P9, P10, P11, P12, P13, P15, P17, P18, and P21 have considerable experience in the maintenance of tide gauge networks and the subsequent quality control of the tide gauge data.
• P1, P4, P7, and P16 have expertise in operating geodetic GPS networks and in particular, the co-location of GPS and tide gauges for determination of vertical crustal motion and tide gauge movements.
• P1, P4, P7, P9, and P20 have experience in high-precision GPS analysis.
• P1, P3, P10, P13, and P19 have experience in the analysis and interpretation of tide gauge records and general time series analyses, while P2 and P14 represent expertise in satellite altimetry.
• P3, P8, P11, P14, and P19 provide expertise in the interpretation of sea level variations as well as the hydrodynamical modelling, and P1 contributes expertise in modelling vertical land movements and sea level variations due to surface loading.

The majority of the participants has been active in COST Action 40 and all are associated with the ESEAS. Through these activities, all partners are actively involved in related activities.
