Fig. 2: Potential drivers of export flux attenuation.
a Relationship between carbon export flux and satellite-derived primary production23 (PP, during the period of deployment); b, c, e, f Export flux attenuation coefficient (Martin-b) and biochemical parameters indicative of particle quality as obtained in the deepest trap of each deployment. Ratios are [g]:[g] in (b, c, f), and [mol]:[mol] in (e); and d export flux attenuation coefficients and temperature as suggested by Marsay et al.29 (dotted line). blue symbols: Martin-b values from well-oxygenated waters (>200 µmol L−1), red symbols: OMZ (<70 µmol L−1) with circles: previously published data (Supplementary Table 3), and triangles: data from this study. All b-values in d were calculated with a reference depth of 100 m for comparison.
