International audience Long-chain polyunsaturated fatty acids (LC-PUFA) are molecules produced at the basis of marine food webs and essential for ecosystem functioning. This study reports detailed fatty acid (FA) composition including the two LC-PUFA 20:5n-3 and 22:6n-3, in suspended organic matter...
