a Shown for each layer (AG) and for both inversions (NA and SP). Layer boundaries are as follows: (A) 0–30 m (B) 30–50 m (C) 50–100 m (D) 100–150 m, (E) 150–200 m, (F) 200–330 m, and (G) 330–500 m. The NA inversion uses prior estimates for aggregation and disaggregation rate constants from the North Atlantic Bloom Experiment (Murnane et al., 1996). The SP inversion uses prior estimates for aggregation and disaggregation rate constants from Station P (Murnane, 1994). SSF and LSF indicate the small and large size fractions, respectively.
