  Abstract: The Island of Cabo Frio is situated a the southeastern tip of the Brazilian coast, by 23 degrees south, at the edge of the tropical to the southern Atlantic ocean. The area is exposed to a strong upwelling regime from south under strong northeastern wind, predominant in spring and summer. A four hydrophone tripod is installed in a 8m depth location since February 2018, circa 20m away from a rocky shore, a settling of abundant invertebrate life, mainly barnacles, snapping shrimp, sea urchins and bivalves. These species are distributed according to the rocky shore zonation pattern, producing sound at different levels, frequency bands and times of the day, forming a characteristic chorus. This work aims at characterizing the recorded bio-acoustic signature, its natural variation throughout the year, as well as its relation with other biotic and abiotic factors, such as water temperature (namelly that due to upwelling), wind, tide and sun light. The relationship between these factors and the bio-acoustic signature variation may contribute to the understanding of rock shore organisms behavior and potentially to biotechnological applications.
