Growth and morphological measurements of the coccolithophore Emiliania huxleyi under three salinity conditions

<p>Three datasets presenting results from laboratory culture experiments with the coccolithophore <em>Emiliania huxleyi</em> (Norwegian coastal strain PLYB11 and Mediterranean Sea strain RCC1232) grown for a duration of 156 h under salinity 25 (hyposaline/low salinity), salinity 35 (control) and salinity 45 (hypersaline/high salinity) conditions.<br><br>Cell concentrations and cell size (mean and standard deviation of triplicate counts) were measured using a CASY automated cell counter. Morphometric measurements of coccolith length, coccosphere size and number of coccoliths per cell were measured on scanning electron microscopy images.&nbsp;</p> <p>Supplementary Fig. S1 shows scanning electron microscopy (SEM) images of E. huxleyi coccosphere from strains PLYB11 and RCC1232 under salinity 25, 35, 45 conditions during the early (first 48 h), middle (76-100 h), and end (last 48 h) of each 156-h experiment.
