The project HOPE<\/em> continues to move forward with the 5th mission of 2024, carried out in November off the coast of New Caledonia.<\/p>

During this mission, the team relieved, refitted and re-deployed the EXPORT-LINE, a 700 m long line anchored from the ocean floor to the surface. Instrumented with 32 sensors and collectors, it samples the marine snow at strategic depths every 2 days to quantify the carbon captured and understand the environmental conditions influencing this process. The operation was a success.<\/p>

Anchored in the South Pacific since March 2024, the EXPORT-LINE, which is surveyed every three months, is a delicate operation carried out by a team of 9 researchers and engineers, as well as 13 sailors aboard the FOF M\/O Antea. This series of campaigns is part of the ERC HOPE project on the role of diazotrophs in the biological carbon pump.<\/p>

The EXPORT-LINE works in tandem with the HOPE'ORTUNITY intelligent buoy, which is equipped with automated systems that measure the physical and biological parameters of the surface ocean (0-100 m) every 4 hours, in particular the biodiversity of the plankton responsible for carbon sequestration.<\/p>

The next 16-day mission will take place in February 2025, to survey the EXPORT-LINE and study very high-frequency processes at the HOPE'ORTUNITY buoy with our American and Pacific colleagues.<\/p>
