Fig. 1: Phytoplankton counts for 5-yr (1–10 m) Bedford Basin (Halifax, NS) time series.
From: Highly-resolved interannual phytoplankton community dynamics of the coastal Northwest Atlantic
a Mean chlorophyll a (chl a) and mean temperature, (b) mean flow cytometry cell counts for Cryptophytes, Eukaryotes, Picoeukaryotes, and Synechococcus. Raw data points are shown as shapes, mean is shown as black lines. c Monthly cell count distributions by water depth and all five years combined. The flow cytometry size range is approximately 1–35 μm. See Supplementary Methods S1 for gate descriptions. The maximum average cell density for each group was: Synechococcus = 2.64 × 108 cells/L [mainly bloomed late August and prior to fall chl a peaks], Picoeukaryotes = 1.23 × 108 cells/L [increased mainly during summer], Eukaryotes = 4.85 × 107 cells/L [mainly increased starting late spring, then occurred throughout the summer with highest counts in August], and Cryptophytes = 2.56 × 106 cells/L [bloomed mainly during summer/August and values were higher at 10 m]. Eukaryotes and Picoeukaryotes also reached higher cell counts in shallower depths (1–5 m). Highest mean chl a reached during the five years = 34.25 mg/m3 ± 18.23 SD.
