We started the day departing at 10am after some long showers in Ardfern. Today was a cloudy and windy day. Actually, we work hard but didn’t have good luck, the result of the day was just two sightings of porpoises. At the end of the day we had Clare’s presentation about ‘marine sounds’. It was great to learn more about how thee animals can communicate. Well, we hope that tomorrow we will be more lucky!

…however with the acoustic equipment working we were now able to hear a more porpoises than we saw, with nice clear porpoise tracks appearing on both computer screens (we’re testing the old and new hydrophones in parallel). For the first time we have actual data on the frequency of our porpoises – nice narrowband (i.e. the clicks only cover a narrow band of frequencies) centred around 137 kHz. Now, it would be nice to see a few more porpoises to confirm some of our theories!
