A very exciting week (June 4-6) at Wimereux for the TT CYTO workshop (Euromarine, JERICO, OBAMA-NEXT). The oportunity to meet many colleagues from France, Europe and Tunisia interested in the characterization of phytoplankton by (automated) flow cytometry. We discussed tips and tricks in data acquisition and analysis. A wonderful occasion to also show what we have done in the #SOMLIT French National monitoring network (IR ILICO) in terms of workflow for the analysis of pico and nanoplankton by cytometry, from the sampling up to the data archiving in databases (CES #ODATIS).
