Vertical distribution of heterotrophic nanoflagellates in the Baltic Proper

This dataset contains data on the abundance of prokaryotes, heterotrophic nanoflagellates (HNF), specific lineages of HNF and environmental factors in the Baltic Sea collected during four cruises of r/v Baltica (National Fisheries Research Institute) in 2021. The Excel file includes six sheets:

1. The "Parameters-Data" sheet lists all parameters for data presented in the "Data" sheet. Column A (Name) contains the variables names, column B (Unit) contains units in which they were measured, column C (Method/Device) contains information on the methodology, and column D (Comments) contains additional information
2. The "Data" sheet contains data in a wide format for all variables listed in the "Parameters-Data" sheet measured at sampling depths. The first row contains variable names (listed in Column A of the Parameters-Data sheet) with units in square brackets
3. The "Parameter-Size" sheet lists parameters for data presented in the "Size" sheet in the same format as described for the "Parameters-Data" sheet. Starting from row 5 in columns A and B, the number of measured HNF cells for each sample is given 
4. The "Size" sheet contains size measurements of HNF in the samples in a long format. The number of cells measured in each sample is provided in the "Parameter-Size" sheet
5. The "Parameters-CTD depth profiles" sheet lists parameters for data presented in the "CTD depth profiles" sheet in the same format as described for the "Parameters-Data" sheet.
6. The "CTD depth profiles" sheet contains full-depth profiles of variables measured with a CTD probe with 1 m resolution.
