The ARION project aim is to protect dolphins and boats, while preserving human activities, mainly preventing collisions. To achieve this goal it is necessary to track both and to signal the presence of the dolphins to possibly any subject operating in the protected area. Two buoys with four hydrophones each, installed in Santa Margherita-Portofino marine protected area, collect data transmitted to a ground station. The average power of noise background is at the same time a parameter affecting resolution and an indicator of noise pollution. The equivalent sea state noise is calculated from this parameter and compared against Wentz curves.

Abstract
The ARION project aim is to protect dolphins and boats, while preserving human activities, mainly preventing collisions. To achieve this goal it is necessary to track both and to signal the presence of the dolphins to possibly any subject operating in the protected area. Two buoys with four hydrophones each, installed in Santa Margherita-Portofino marine protected area, collect data transmitted to a ground station. The average power of noise background is at the same time a parameter affecting resolution and an indicator of noise pollution. The equivalent sea state noise is calculated from this parameter and compared against Wentz curves.
