Abstract: Tab. S1: Particles fluxes and their transfer efficiencies (T) according to the sampling dates for both AMOP1 and AMOP2 datasets.T is determined from %Flux 149m /Flux 34m and its uncertainty from logarithmic expansion calculation, and b coefficient from the Martin's curves theory (Suess, 1980; Martin et al., 1987).Italic and non-italic values correspond to the fluxes at 34 m and 149 m, respectively.On the last lines of the table, bold colored values in red, yellow and blue correspond to particles fluxes averaged values for low, intermediate and high T eff ranges, respectively, with the relative standard deviation between samples (±SD%).Analysis accuracy on the particles total mass fluxes is ±3%, inducing an absolute uncertainty on their vertical transfer efficiency estimated from a logarithmic expansion of ±6% (cf.Methods).Tab. S2: Organic elemental fluxes and their transfer efficiencies according to the sampling dates for both AMOP1 and AMOP2 datasets.a), b), c) and d) POC, PON, POP and BSi fluxes in mg.m -2 .d - , mmol.m -2 .d - and mol% (on POC+PON+POP+BSi), and their transfer efficiency in % (T eff , T effPON ; cf.Table 1 caption for calculation) in terms of Particulate Organic Carbon (POC), Nitrogen (PON), Phosphorus (POP) and Biogenic Silica (BSi) according to the sampling dates for both AMOP1 and AMOP2 datasets. For a), b), c) and d), italic and non-italic values correspond to the fluxes at 34 m and 149 m, respectively. On the last lines of the table, bold values correspond to particles fluxes averaged values for low, intermediate and high T eff ranges, with the relative standard deviation between samples (±SD%). Analysis accuracies on the elementary fluxes are ±0.2% for both POC and PON, ±3% for POP, and ±5% for BSi, inducing an absolute uncertainty of ±0.2% (T eff ), ±0.2% (T effPON ), ±3% (T effPOP ) and ±5% (T effBSi ) on the transfer efficiency (cf. Methods).Tab. S3: Molar ratios and their transfer efficiencies according to the sampling dates for both AMOP1 and AMOP2 datasets.a) Values of elementary ratios (C:N, C:P and N:P) and transfer efficiency of these ratios in % (T effC:N , T effC:P , and T effN:P ; cf.Table 1 caption for calculation) according to the sampling dates for both AMOP1 and AMOP2 datasets.b) Values of elementary ratios (Si:C, Si:N and Si:P) and transfer efficiency of these ratios in % (T effSi:N , T effSi:N and T effSi:P ; cf.Table 1 caption for calculation) according to the sampling dates for both AMOP1 and AMOP2 datasets. For a) and b), italic and non-italic values correspond to the fluxes at 34 m and 149 m, respectively. On the last lines of the table, bold values correspond to particles fluxes averaged values for low, intermediate and high T eff ranges, with the relative standard deviation between samples (±SD%).Analysis accuracies on the elementary ratios are ± 0.4, 3.2, 3.2% and ± 5.2, 5.2, 8% for C:N, C:P and N:P and for Si:C, Si:N and Si:P, respectively, inducing an absolute uncertainty of ±0.9% (T effC:N ), ±6.3% (T effC:P ), ±6% (T effN:P ), and of ±12% (T effSi:C ), ±13.4% (T effSi:N ) and ±19% (T effSi:P ) on the transfer efficiency cf.Methods.Classical (reference) molar ratios have been reported on the second lines from Redfield et al. (1963) and Brezinski (1985). Tab.

Tab.
