this turbine does get barnacle growth on it, and then that becomes food for fish. ah ha. during slack tide, there are fish around these turbines. which would attract these little mammals. which will attract predators. it s a little feeding ground. 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. and in the past, sort of early 20005, between orkney and the north coast here, we d have had about 9,000 harbour seals. and unfortunately, over the last 10 15 years, we ve lost about 85% of those animals. 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
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
this has been in the water for about two years. this turbine does get barnacle growth on it and that does become food for fish. during slack tide, there are fish around these turbines. which would attract these mammals. which would attract predators. 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

growth on it and that does become food for this. during slack tide there is fish around these turbines. which would attack visible mammals. it would attack predators. the question is, as the flow increases and the turbine goes into production and the blades been faster, jennifer tramaine, julie predators come back, do we have an impact on on its predators, and it is a detrimental impact? and it is crucial to detrimental impact? and it is crucial to develop detrimental impact? and it is crucial to develop these - detrimental impact? and it is| crucial to develop these kinds of turbines in a way that doesn t harm these creatures, which are already under threat from other factors. which are already under threat from otherfactors. irate which are already under threat from other factors. from other factors. we are certainly from other factors. we are certainly seeing from other factors. we are certainly seeing that - from other factors. we are certainly seeing that these j certainl
