Fluxes of organic carbon, biominerals and estimated diatom carbon into the traps have already been published (Martin et al., 2011 and Rynearson et al., 2013). The chl-a flux into the BMS-345541 traps was 0.04–0.2 mg m− 2 day− 1 during Deployment 2, 1.5–2.9 mg m− 2 d− 1 during Deployment 3, and 0.2 and 1.5 mg m− 2 d− 1 during Deployment 4 (Fig. 3, Table 2).

3.2. Spatial variability in chl-a transformation products
It is important to note that water column samples (suspended particles) analyzed in this study were collected from both inside and outside the bloom patch. The stations were geographically scattered (cf. Fig. 1) and the bloom exhibited ‘patchiness’ (Martin et al., 2011). An assessment, based on temperature and salinity of the water mass ((Briggs, 2014); Table S3), determined that eight casts were from inside the patch. No relationship was found between samples being in or out of patch and their chl-a transformation products. Indeed, the only significant effect on the concentration and distribution of chl-a and its transformation products was the loss of diatoms from the euphotic zone.
