The service works on datasets structured according to the Phytoplankton Data Template that can be selected by the GUI or uploaded by the researchers. The input file is in CSV format with some mandatory fields (density, biovolume or cell carbon content). Before selecting or uploading the input file, users have to specify some parameters (e.g., the trait to be used for the size distribution, the taxonomic level for the size distribution and the spatial and temporal levels for the clusterization of data). The web service provides as output a zip file containing two summary tables in csv format and a scatter plot. functional traits biovolume phytoplankton traits carbon content distribution size density WWW:LINK-1.0-http--link https://www.phytovre.lifewatchitaly.eu/size-density-relationship/ WWW:LINK-1.0-http--link https://www.phytovre.lifewatchitaly.eu/phyto-data-template/ copyright Fully Open Access Italian Agency for the Environmental Prevention and Protection · Centro Regionale Mare (CRM)- Bari LifeWatch ERIC Service Centre Institute of Research on Terrestrial Ecosystems (IRET), National Research Council (CNR) University of Salento, LifeWatch Italy Elena Stanca Lucia Vaira Maria Teresa Manca Francesco Cozzoli Jessica Titocci Ilaria Rosati Alberto Basset
