The BBC has a lovely article about a piece of digital art that can be found at Tingrith Fisheries. Fish in the lake at the fishery are tracked hydrophonically and their movements translated into a soundscape and an animated representation of the fishes’ movements. How is this done? The fish are “slit open and miniature bio-acoustic tags are inserted into their bodies. The fish are then stitched up, woken up and returned to the lake where they emit a tiny acoustic signal every two seconds. ” Lovely. Just the type of detail you want to know.
The article is also notable for me in that its the first one I’ve seen where there is the option to download an audiofile and subscibe to the RSS feed for the podcasts, as part of the BBC Download Trial
