and the question is then, as the flow increases and the turbine goes into production and the blades spin faster, do the fish remain, do the predators come back, do we have an impact on those predators, and is it a detrimental impact? and it s crucial to develop these kinds of turbines in a way that doesn t harm these creatures, which are already under threat from other factors. we are certainly seeing that these areas seem to be important for harbour seals around this area and, indeed, we do see animals coming relatively close to the turbines, but it s really that fine scale behaviour that we re interested in. what do animals do when they really come close to the turbines? to answer this unknown, sinking a monitor next to a turbine might be key. so, douglas, this is going to be submerged underwater? can you take us through the technology here? that s right. of course, yeah. so, the two main sensor technologies we ve got are the active sonars we re using for tracking seals, primarily, s
submerged underwater? can you take us through the technology here? that s right. of course, yeah. so, the two main sensor technologies we ve got are the active sonars we re using for tracking seals, primarily, so they don t make much noise underwater, so these send out a very, very high frequency ping which is too loud for the animals to hear and be disturbed by, and they listen for the echo, and they can build up an image of exactly where the animals are around the turbine. and the other sensor that we ve got is underneath this protective housing here, which is passive hydrophones, which are listening to the sounds the animals make and we use those to pick up the sounds of porpoises and dolphins. john 0 groats it s here that the monitor will be sunk underwater and installed on the seabed next to the turbine. it s sam, the ship is out at sea, we re here on land waiting for the signal, and that s because there is only a certain number of opportunities for the equipment to be submerged
so the due main sensor technologies that we have our active soon as using for tracking seals, primarily, so they don t make noise underwater, so they send out a very, very high frequency ping which is too loud for the animals to hear and be disturbed by, and they listen for the echo, and they can build up an image of exactly where the animals are around the turbine. on the other sensor that we ve got is underneath this protective housing here, which is the passive hyper queens beach are listening to the sounds the animals make and we use those to pick up the sounds of porpoises and dolphins. jahh porpoises and dolphins. john o groats. porpoises and dolphins. john o groats. it porpoises and dolphins. john o groats, it is porpoises and dolphins. john o groats, it is here - porpoises and dolphins. john o groats, it is here the - o groats, it is here the monitor will be sung underwater and installed on the seabed next to the turbine. it s 5am, next to the turbine. it s sam, the ship
