Coccolithophore Abundance, Size, Carbon And Distribution Estimates (CASCADE)

<div>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.</div> <div>&nbsp;</div> <div>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" (&gt;20 obs) and "rare" (&lt;20 obs) species and their number of observations.</div> <div>&nbsp;</div> <div>The CASCADE data set can be easily reproduced using the scripts and data provided in the associated github repository: <a title="Opens in new tab" href="https://github.com/nanophyto/CASCADE/tree/v0.1.1" target="_blank" rel="noopener">https://github.com/nanophyto/CASCADE/</a> (<a href="../doi/10.5281/zenodo.12797197">zenodo.12797197</a>)</div> <div> <p>Correspondence to: Joost de Vries, joost.devries@bristol.ac.uk</p> <p>v.3 fixes:</p> <ol> <li><em>actually</em> fixes Guerreiro et al., 2023 longitude issue</li> <li>replaces negative PIC predictions from GLM with NA (an issue with some small HOL species)</li> </ol> <p>v.2 fixes:</p> <p>1. The wrongly specified <em>S. neapolitana</em> was removed from synonyms.yml (this species is now<em> S. nana</em>)<br>2. Longitudes were corrected for Guerreiro et al., 2023<br>3. A double entry for Dimizia et al., 2015 was fixed<br>4. Units in Sal et al., 2013 were correct to cells/L (previously cells/ml)<br>5. Data from Sal et al., 2013 was re-done, as some species were missing<br>6. Duplicate entries from Baumann et al., 2000 were dropped</p> </div>
