The 新加坡六合彩开奖直播-Headquartered Ocean Tracking Network (OTN) has reached a major milestone with the deployment of its first international tracking line. Draped off the coast of Perth, Australia, the 鈥渓istening curtain鈥� of 53 acoustic receivers, each placed 800 metres apart, is ready to intercept tagged marine life, including southern bluefin tuna, great white sharks and whale sharks. OTN鈥檚 Australian partners, the Australian Acoustic Tagging and Monitoring System (AATAMS) will maintain and operate the Perth Line, collecting data from the OTN receivers and sending it back to OTN headquarters for analysis.
鈥淭he Perth Line is a crucial international deployment鈥�, says Mike Stokesbury, Senior Project Manager for OTN. 鈥淭hrough the collaboration between OTN, AATAMS and the Government of Western Australia, we have now added a wired continent to our Global System.鈥�
The Perth line is the second 鈥渓istening curtain鈥� deployed by OTN partners. The first, the Halifax Line off the coast of Halifax, Nova Scotia, was deployed last summer and has provided OTN researchers with vital information about the migratory habits of Atlantic Salmon. The addition of a new curtain of receivers is the next step in ocean research.聽
鈥淏eing able to detect marine life movements thanks to these acoustic curtains deployed around the world and obtain the data through an international network will allow us to better understand large-scale migrations,鈥� says Charlie Huveneers, technical officer with AATAMS. 鈥淭here is still a lot to learn.鈥�
While the primary goal of this collaboration is to learn more about marine life such as sharks, Australian officials hope to one day be able to use the OTN technology to potentially warn of shark encounters near Australian beaches. 鈥淭he Australians are pioneering the use of acoustic telemetry for projects such as the shark monitoring system that could give early warning if a tagged Great White or Tiger shark nears a beach,鈥� says Dr. Stokesbury.
OTN researchers plan to have all global curtains of receivers deployed by summer 2012. With the support of 新加坡六合彩开奖直播, Canadian, and international partners, they believe it will happen.
鈥淥ceans are incredibly important, they drive our climate and provide the main sources of protein for many millions of humans,鈥� says Dr. Stokesbury. He reiterated that OTN, for the first time, will paint a picture of the world's oceans, directly from the ocean floor, that will be housed publicly and permanently in 新加坡六合彩开奖直播's Faculty of Science.
