Prochlorococcus, Synechococcus and picoeukaryotic phytoplankton abundance climatology in the global ocean from quantitative niche models.

<p>Prochlorococcus, Synechococcus and picoeukaryotic phytoplankton estimated mean cell abundance (cells/ml) in 1-degree grids for 25 layers from 0m to 200 m depth. Cell abundance was estimated with&nbsp;quantitative niche models for each lineage (Flombaum et al., 2013; Flombaum et al., 2020), inputs from the monthly mean of temperature and nitrate from the World Ocean Atlas (Boyer et al. 2013), and PAR from MODIS-Aqua Level-3 Mapped Photosynthetically Available Radiation Data Version 2018 (NASA Ocean Biology Processing Group, 2017).</p>

<p>For&nbsp;annual climatology, the annual mean represents the average of the 12 months for each grid cell.&nbsp;</p>
