We found an error of the species identification on the PIROP dataset.
The dataset recorded the Atlantic spotted dolphin and the Pantropical spotted dolphin correctly but during the data import process, these two were given opposite scientific names and hence Taxonomic Serial Numbers (TSN).
This is an error caused on the OBIS-SEAMAP side, not on the provider's side.
These mismatch is fixed now. Please be encouraged to redo your analyses if these species were targeted in your analyses.
