Outi left Disko Bay last monday but the bowhead whale acoustic team continues its path. Right now Laia is getting a great help from John Jakobsen who is assisting in the field work. In the extreme environment conditions of Arctic it is important not to be alone when going outdoors.
Qaqqaliaq Passive Acoustic Monitoring Station it is still presenting some radio noise signals as mentioned in the last post. We have received some special gear from a telecommunication technician in Aasiat which is normally used to block the strong radio noise (like the MF) from electronic systems. Laia installed the pieces into the PAM system but it seemed to be not strong enough to stop the radio from getting into the system. So, no luck with that yet..
Today John and Laia went to Qaqqaliaq to try something new. It didn’t really work but at the end the radio seemed to be a little less loud.
About the Playback experiments, we have now performed four days of sound emissions, today was supposed to be the 5th day of playback but we had to postpone it until tomorrow due to the NW wind.
Our playback location it’s facing west, so we would have been totally exposed to the wind and because of the wind chill factor it would have felt easily 10 or 15 degrees less than the actual -20 degrees, so -30 or -35 degrees! Having in consideration the time that it takes to setup the playback experiments from the start time (when we pack all the gear into the wagon and we are ready to leave Arctic Station with the snow mobile) until the end time (when we get all the gear indoors), it’s important to realise when it will be too cold for it.
