International audience The lipid content of seven samples of sinking particles collected with sediment traps moored at ∼ 100 m depth in summer and fall across the Canadian Beaufort Shelf (Arc-tic Ocean) was investigated. Our main goal was to quantify and characterize the biotic and abiotic degradati...
