Metadata: Flow cytometry data derived from samples collected from the Celtic Sea in 2018
Abstract:
These data contain information on the abundance and fluorescence of 6 phytoplankton functional groups based on flow cytometry measurements. The data covers 2 surveys on the RV Cefas Endeavour, CEND0518 and CEND1718, both in the Celtic Seas.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Flow cytometry data derived from samples collected from the Celtic Sea in 2018 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFAS444df849-781a-4211-a464-96131cfcf9c6 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS20363 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2018-03-15 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2018-11-10 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | asNeeded |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | A CytoSense fixed beam scanning flow cytometer, fitted with a 488nm blue argon laser was used to measure phytoplankton size and abundance. The flow cytometer was connected to the ferrybox on board the RV Cefas Endeavour with a continuous water intake at approximately 4m depth. Samples were analysed inline for 10 minutes each hour without the addition of a fixative. Data file cleaning (removal of debris) and calibration (using a microsphere of known size, and a microsphere with strong yellow fluorescence; F8852, Life Technologies, USA) was carried out with CytoClus v3 software (CytoBuoy, the Netherlands). Standardised phytoplankton functional types were agreed with partners in the Jerico next project to be picophytoplankton (broken down into synechococcus and eukaryote picophytoplankton), nanophytoplankton (broken down into coccolithophores, cryptophytes, and eukaryote nanophytoplankton), and microphytoplankton. Abundances of phytoplankton functional types (cell l-1) were estimated based on size classes (from forwards scatter measurements of each cell) and particle fluorescence. Locations for samples were obtained from the FerryBox system. |
