Welcome to our website

Welcome to the website of Oceanomare Delphis Onlus! Our association consists of experts and enthusiasts who want to work for the conservation of cetaceans in the Mediterranean Sea. We do this by studying them in the open sea, in their natural environment, using non-invasive methods, and aboard a sailboat. More than 30 years ago, we chose the Pontine and Campanian Islands archipelagos as our study area. Sailing between these islands, we monitor the health of the cetacean populations present.

Seven cetacean species live in our study area: three species of beaked dolphins, two species of large dolphins, and two sea giants inhabit the waters around the archipelagos. The biodiversity of this area has been documented over time and has led to protective works such as Marine Protected Areas and Important Marine Mammal Areas. Learn about our cetaceans by browsing through the animal files.

Marine Mammal Observer (MMO) & Passive Acoustic Monitoring (PAM)

Since 2015, in collaboration with CIBRA (Interdisciplinary Center for Bioacoustics and Environmental Research), we have been developing plans for monitoring and mitigation of marine mammals in the Mediterranean Sea and conducting related sampling and reporting.

As ACCOBAMS trainers, we organize dedicated courses to train MMO (Marine Mammal Observer) and PAM (Passive Acoustic Monitoring) operators, experts in identifying cetaceans and listening to their vocalizations.
