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
which is too loud for the animals to hear and be disturbed by. then they listen for the echo, and they can build up an image of exactly where the animals are around the turbine. then the other sensor that we ve got on it is underneath this protective housing here, which is the passive hydrophones, which are listening to the sounds that the animals make. and we can use those to pick up the sounds of porpoises and dolphins. i ve also noticed this, douglas. yeah. then there is the great umbilical cable. so, the optical fibres that are bringing the data ashore are actually about as thick as a human hair. wow, 0k. but they re inside all of this, with a whole load of steel clamped in there too, just to make it heavy enough to lie on the seafloor. but no one said this was going to be easy. the journey to the far north of scotland begins.
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

got on it, active sonar- is that we are using to track the seals, primarily, - who might make much noise underwater, so these standout in very high frequency pink, i which is to lead for the arms to hear or be disturbed by, i they listen for the echo - and they can build up an image of exactly where the animals are around the turbine. - the other centre that we have got on it is underneath this. protective housing here, i which is the passive hydra phones, which are listening. to the sounds that the animals make and we can use those to pick up the sounds - of porpoises and dolphins. i have also noticed this, douglas. then there is the great umbilical cable. - the optical fibres that - are bringing the data sure are actually about as thick as a human hair. - they are inside all of this with they are inside all of this with a they are inside all of this with a lot they are inside all of this with a lot of they are inside all of this with a lot of steel- they are inside all of this
