Description
CASCADE is a global dataset for 139 extant coccolithophore taxonomic units. CASCADE includes a trait database (size and cellular organic and inorganic carbon contents) and taxonomic-specific global spatiotemporal distributions (Lat/Lon/Depth/Month/Year) of coccolithophore abundance and organic and inorganic carbon stocks. CASCADE covers all ocean basins over the upper 275 meters, spans the years 1964-2019 and includes 33,119 taxonomic-specific abundance observations. Within CASCADE, we characterise the underlying uncertainties due to measurement errors by propagating error estimates between the different studies.
Full details of the data set are provided in the associated Scientific Data manuscript. The repository contains five main folders: 1) "Classification", which contains YAML files with synonyms, family-level classifications, and life cycle phase associations and definitions; 2) "Concatenated literature", which contains the merged datasets of size, PIC and POC and which were corrected for taxonomic unit synonyms; 3) "Resampled cellular datasets", which contains the resampled datasets of size, PIC and POC in long format as well as a summary table; 4) "Gridded data sets", which contains gridded datasets of abundance, PIC and POC; 5) "Species lists", which contains spreadsheets of the "common" (>20 obs) and "rare" (<20 obs) species and their number of observations.
The CASCADE data set can be easily reproduced using the scripts and data provided in the associated github repository: https://github.com/nanophyto/CASCADE/ (zenodo.12797197)

v.3 fixes:
- actually fixes Guerreiro et al., 2023 longitude issue
- replaces negative PIC predictions from GLM with NA (an issue with some small HOL species)
v.2 fixes:
1. The wrongly specified S. neapolitana was removed from synonyms.yml (this species is now S. nana)
2. Longitudes were corrected for Guerreiro et al., 2023
3. A double entry for Dimizia et al., 2015 was fixed
4. Units in Sal et al., 2013 were correct to cells/L (previously cells/ml)
5. Data from Sal et al., 2013 was re-done, as some species were missing
6. Duplicate entries from Baumann et al., 2000 were dropped
