ORION 1 campaign

Campaign position on map

Abstract
ORION is the first underwater network of multiparameter seafloor observatories, based on GEOSTAR and two new multiparameter satellite observatories (nodes). This system was successfully operated in a mission in Southern Tyrrhenian Sea, at the base of Marsili volcano (3320 m w.d.)

Purpose
In ORION (Ocean Research by Integrated Observatory Networks), GEOSTAR was implemented to act as the main node of an underwater network of deep-sea observatories.
GEOSTAR was equipped with an acoustic subsystem devoted:
1) to a vertical communication, used to transmit data of the observatory network to the surface buoy;
2) to the horizontal communication among the nodes ("horizontal" acoustic link) receiving data from the satellite nodes.
