The MOOSE-GE cruises aim to provide an annual summer snapshot of the North-Western Mediterranean Sea basin, to observe changes in water mass properties, biogeochemical content and changes in planktonic biodiversity. These cruises are part of the national MOOSE program (Mediterranean Ocean Observing System for the Environment) funded by CNRS-INSU and the Research Infrastructure ILICO (French Ministry). Each year, samples are analyzed for phytoplankton pigments by the national analytical service, SAPIGH. The SAPIGH platform (based at IMEV, Villefranche/Mer) is certified by INSU-CNRS. It is dedicated to HPLC (High Performance Liquid Chromatography) measurement of phytoplankton pigments (chlorophylls and carotenoids) in the marine environment (https://lov.imev-mer.fr/web/facilities/sapigh/).
