The JULIO mooring (Judicious Location for Intrusion Observation (PIs: Anne Petrenko and Jean-Luc Fuda, project initiated in 2012 with 3 series of measurements already available) was relaunched on 7 December 2020The ADCP will be installed on a 100m deep seabed off Marseille, on the edge of the Calanques National Park. Its ADCP will measure the speed of the current every 1/2 hour and every 5m for 12 months in the water column above the mooring.
JULIO will detect the arrival of offshore water masses in the Golfe du Lion, a phenomenon known as the " North Current intrusions "It will also provide reference data for setting up algorithms to study coastal circulation using satellite altimetry measurements (Casella et al., 2020).
The aim is to incorporate this mooring into the MOOSE National Observation Service of the north-western Mediterranean. It will thus be able to take part in the long-term monitoring of the impact of climate change on the circulation of this area which, being located at the transition between the offshore and coastal domains, is a key and very sensitive zone for these issues.
Thanks to the OPLC team at the MIO for supporting JULIO, to all the staff at the SAM for their contribution to preparing the mooring and to the crew of the Antédon II for the smooth launch.
