©2020 Biological and Chemical Oceanography Data Management Office.Particulate organic carbon (POC) concentration was measured in seawater samples collected from nutrient amendment experiments conducted on surface water collected at the Long-Term Ecological Monitoring Station, MareChiara, in the Gulf of Naples, Italy, between April 20 and May 19, 2022. These incubations were part of a field study on "Diatom Virus Infection of Natural Communities" (DaVINCi) and were aimed at understanding the role of silicon limitation in driving diatom viral infection.

Seawater was transfered from incubation bags to acid-cleaned bottles using a siphon and acid-cleaned tubing. Samples for particulate organic carbon concentration (POC) determination we filtered onto pre-combusted 25-millimeter (mm) GF/F filters and stored at -20 degrees Celsius (°C). The analyses are carried out using a Thermo Scientific Flash EA 1112 elemental analyzer (Thermo Fisher Scientific) following Hedges and Stern (1984) and using cyclohexanone-2,4-dinitrophenylhydrazone as standard.
