Abstract

This dataset is the output of a one-dimensional model that simulated the time evolution of growth of Synechococcus phycoerythrin pigment types, with low, high, and variable ratios of phycourobilin to phycoerythrobilin (PUB:PEB; pigment types 3a, 3c and 3d, respectively). The model used to generate the output was built on existing published equations of competition for light color within an ocean water column by Stomp and coworkers. Our version of the model was coded in MATLAB, and the depth of the water column was made variable. Additional absorption by chlorophyll and coccolithophores were added as options to the standard absorption by seawater. All growth and photosynthetic parameters for the Synechococcus strains were kept constant except for their specific absorption spectra, with the 3d chromatic acclimater having a variable absorption spectrum. This ensured differences in growth were only attributed to differences in light color absorption. The model solution yielded the relative abundance of the three cyanobacteria pigment types integrated across the one-dimensional layer, and results from all simulations are contained within this dataset.
