REFMAR's objectives and motivation

SHOM is the national reference for the "sea level" in all zones under French jurisdiction. As such, it fulfils, through REFMAR, various coordination functions concerning the collection and issuing of public data relating to sea level observation, so as to promote their use in a wide range of applications.

Key missions

REFMAR meets the objectives assigned to SHOM as set forth in the instruction of the Prime Minister on sea level observations and the management and dissemination of the resulting data, namely:

  • coordinate the collection of sea level observations conducted by public establishments and services;
  • manage and archive the observations collected as time-delayed data;
  • define the networks and minimum specifications for observing the sea level;
  • define and promote appropriate means of operational transmission;
  • coordinate the real-time and time-delayed distribution of the observations;
  • check the conformity of the observations received;
  • define, distribute, promote and monitor national and international standards (GLOSS);
  • contribute to representing France in the international and European observation organizations.

 

Competence in France and in French Overseas Territories

The role of coordination extends to all areas under national jurisdiction, that is to say, in France and in French Overseas Departments and Territories.
