The continuous and gentle pumping of seawater from the Calanque aux Cuivres to taps under laboratory conditions is a success, validated by its almost continuous operation. Similarly, the method of cleaning the seawater inlet pipes is a well-managed routine. The high-frequency, long-term strategy enables the diurnal and seasonal cycles of a coastal marine ecosystem to be studied, and aims to capture the effects of impulse events such as gales, storms and rainfall on phytoplankton communities, certain chemical and hydrological elements, and their transformation products.<\/p><p class=\"rtejustify\">So we measure for science and for the community:<\/p><ul><li class=\"rtejustify\">meteorology, <a href=\"https:\/\/meteo-osu.osupytheas.fr\" target=\"_blank\" rel=\"noopener\">available on the OSU weather site<\/a>station installed by Lars-Eric Heimb\u00fcrger-Boavida and Deny Malengros<\/li><li class=\"rtejustify\">hydrology (STPS temperature and salinity sensors (Fabrice Garcia and Patrick Raimbault), spot sampling of nutrient salts (PAPB platform))<\/li><li class=\"rtejustify\">phytoplankton (observation of functional diversity every two hours) using the automated cytometer at the <a href=\"mailto:SSL@MM\">SSL@MM<\/a> and PAR (Photosynthetic Available Radiance)<\/li><li class=\"rtejustify\">the production of dissolved oxygen by biological activity thanks to the installation of a MIMS spetrometer (Oliver Grosso, Dominique Lefevre)<\/li><\/ul><p class=\"rtejustify\">Le <a href=\"mailto:SSL@MM\">SSL@MM<\/a>It's also about welcoming researchers and training students.
