Summary from DNA content analysis of samples collected from the IFCB support raft during weekly NMS surveys. Only depths where A. fundyense concentrations were greater than 20,000 cells L⁻¹ were analyzed. The proportion of 2c cells reported from 17 April is adjusted according to differences in cell abundance between depths. Projected ${\mu }_{\mathrm{div}}$ values are calculated under the assumption that all 2c cells will divide during the next phased division and are compared to estimates of ${\mu }_{\mathrm{div}}$ from comparisons of mean cell volume ( $\overline{V}$) before and after phased division the same day the DNA content sample was taken.
