The ADRIA-Watch project is a scientific observatory for large marine vertebrates of the Northern Adriatic Sea. Data are collected and pooled together into one single database, working towards a better understanding and dealing of the problems affecting the large inhabitants of the area and to promote public awareness. ADRIA-Watch collects data on sightings and strandings of Cetaceans (dolphins and whales), marine turtles and sharks along our coasts. ADRIA-Watch also contributes to a sharing of knowledge: web site, public conferences, scientific seminars, didactic material and educational projects. In the framework of this project 5 satellite-tracked loggerhead turtles will be released in 2006, from five different sites in the northern Adriatic sea, from both Eastern (Slovenian and Croatian) and Western (Italian) shores.
