SISMER's activities come under a specific marine data management programme with a dual vocation:
- to ensure the continued operability and accessibility of observation data acquired by Ifremer marine observation facilities for the benefit of the entire national community: ships, submersibles, observatories. This first mission falls under the continuity of the SISMER activities and fulfils Ifremer's statutory obligations (article 6 of Chapter I of the order by which the institute was established).
- to provide technical support for the institute's thematic programmes by offering reliable data management services: collection by automated observatories, quality control, formatting and basic processing, data distribution and information. This service activity is conducted according to specifications defined in collaboration with the scientific teams.
