FIG. 1.
Vertical profiles of SRRs at 13:05 (black bars), 21:25 (gray bars), and 23:00 (white bars) on 10 July 2001 and sulfate concentrations (dashed lines) from 28 June 2001. Note breaks and changes in scale on the sulfate depth axis. An error bar denotes 1 standard deviation (n = 3 or 4) or a range (n = 2). *, n = 1. Integrated SRRs (μmol cm−2 day−1 [d−1]), overall depths, and proportions of total SRRs above (% oxic) and below (% anoxic) the oxycline calculated for each sampling time are in the inset.
