This dataset is formatted in DarwinCore Event Core. It is incorporated in EurOBIS and available through the EMODnet-Biology portal. The following WFS request returns the raw data used by read_cpr.r:

In the file read_cpr.r we preprocess the data so it can be easily ingested for the BlueCloud product generation:
- we select a subset of all columns
- we filter on the target species: Temora longicornis, Calanus finmarchicus, Calanus helgolandicus, Metridia lucens.
- for Acartia and Oithona species, we combine all species to genus level Acartia and Oithona
- we add the aphia id as extra variable
- we convert the counts and sample size (volume) to abundance in individuals/m³ (ind/m³)
- we calculate the log(abundance + 1)
- we export the data to
data/derived_data/data_cpr.csv
- There are a number of records without counts available. Thus, abundances and log abundances could not be calculated. These are added to the processed data in
data/derived_data/data_cpr.csvwithNAvalues
