Our aim

The aim of MAP-IO is to study atmospheric composition and ocean-atmosphere processes with an impact on regional climate and numerical weather prediction.
This scientific program is based on the banking of oceanic and atmospheric data by equipping the Marion Dufresne vessel with 19 permanent, autonomous atmospheric measurement systems.

The MAPIO project is described in detail in a dossier that has been submitted to the Commission Nationale de la Flotte Hauturière (CNFH) for approval. This file can be dowloaded here and in December 2019, the CNFH issued a very favorable opinion and classified the MAP-IO request as Priority 1. This classification is valid for the realization of one campaign per year for 4 years (2021-2024). You can read the minutes of the CNFH's opinion here. here

Next or current mission

OP1 2024 (March 24 to April 16, 2024)

Under TAAF charter, the Marion Dufresne mainly carries out rotations to the Austral Islands. These rotations are called Opérations Portuaires (OP) and take place on average 4 times a year. The main objectives of these OPs are:

➢ the succession of scientific and technical staff
➢ supplying bases with food, diesel and materials for building sites
➢ support for technical, scientific and conservation activities in local areas
