Pelagic Size Structure Database (PSSdb)
PSSdb-MERGED v2024-04
This initial dataset is composed of two products, separated by imaging device:
- Product 1a includes size distributions calculated from normalized biovolume (NBSS) and normalized abundance (PSD) of plankton and particles within a set of pre-defined size classes (expressed in both biovolume and equivalent circular dimater), averaged by year and month, and in 1-degree longitude/latitude grid cells.
- Product 1b includes the results of NBSS and PSD regression fit parameters (slopes, intercepts, coefficient of determination R2), averaged by year and month, and in 1-degree longitude/latitude grid cells. The regression parameters are defined using ordinary least squares linear regressions applied to log10 transformed normalized biovolume / normalized-abundance and biovolume / diameter-size class values.
