Of these habitats, how are they're using these highly tidal areas around the north coast of scotland. and we are certainly seeing that these areas do 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 really 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 ri...

Oh, yeah. we have one on the end of the slip down here, yeah. so, some of the initial research was actually designed to look at how animals are actually using some of these habitats, how are they using these highly tidal areas around the north coast of scotland. and we are certainly seeing that these areas do 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 really interested in. what do animals do when they really come close to the turbines? to answer this unknown...

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'...

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 ...

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. j...
