Figure 3. Lipid fluxes at the Crozet abyssal locations, +Fe and HNLC at 3195 and 3183 m water depth in 2005.

Labile lipids: Polyunsaturated fatty acids (PUFA), monounsaturated fatty acids (MUFA) and unsaturated alkanols (U-ALK); Semi-labile lipids: Saturated fatty acids (FA), branched fatty acids (Br-FA) and n-alkanols (ALK); Refractory lipids: Sterols (STER) and other lipids including branched alkanols, triterpenoids, steroidal ketones, phytol derivatives and alkenones (OLIP).
