Some marine mammals travel thousands of kilometres to find their food, continuously diving to great depths. By instrumenting them, it is possible to directly observe their foraging behaviour. Simultaneously, we collect unique oceanographic data in the remote Polar regions.

The MEOP consortium (MEOP stands for "Marine Mammals Exploring the Oceans Pole to Pole") brings together several national programmes to produce a comprehensive quality-controlled database of oceanographic data obtained in Polar Regions from instrumented marine mammals. 

This website presents the MEOP project, and the members of the MEOP consortium. It also makes the quality-controlled MEOP-CTD, MEOP-SMS and MEOP-TDR databases publicly available to the scientific and operational oceanography communities.

Since 2020, AniBOS (Animal Borne Ocean Sensors) has been launched to pursue and further the goals of MEOP on a broader scale. AniBOS is an emerging network of the Global Ocean Observing System (GOOS). AniBOS has been endorsed by the UN Ocean Decade as one of 94 new Decade Actionsin October 2021.
