Introduction PSSdb Data
Pelagic Size Structure Database (PSSdb)
 
PSSdb v2023-10

[ There is a newer version available of this dataset. ]

This dataset is an update to the first release of the Pelagic Size Structure database (PSSdb) scientific project, investigating the global particle size distributions measured from multiple pelagic imaging systems. These devices include the Imaging Flow Cytobot (Olson and Sosik 2007), the ZooScan (Gorsky et al. 2010), and the Underwater Vision Profiler (Picheral et al. 2010). The data sources come from Ecotaxa (https://ecotaxa.obs-vlfr.fr, Ecopart (https://ecopart.obs-vlfr.fr), and Imaging FlowCytobot dashboards (https://ifcb.caloos.org/dashboard and https://ifcb-data.whoi.edu/dashboard).

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.
