Marine mammals and sonar

A six-year program to record and protect nine emblematic, but also vulnerable species of the Greek marine fauna was launched a few days ago with the participation of educational and research institutions and environmental organizations.

The European program called "LIFE MareNatura - conservation of marine megafauna species in Greece and Italy" has a budget of 11 million euros. 

A lonely whale, dubbed 52, has caused many to empathize. The creature has roamed the world in search for a companion but never gets an answer to its sounds. The solitary whale has been named 52 due to the 52-hert frequency of its mating calls that have been picked up by navy sonar detectives.
