It was at Sunday 19th of September 2021 that I suddenly decided to go on sea to record with the hydrophone. The weather- and tide forecast promise me a few hours of decent circumstances.
But when I arrive at the harbor, people there like to chat about my kayak and equipment. So when I finally went on I was getting late. The wind had increased and the tide was getting too low for the place where I was heading to, so after 4 km paddling I ended up beside a pier in Viðey island which is only 800m NE from Reykjavik Sundahöfn harbor.
I tied my boat to the pier and put the hydrophone about three meters below the boat. It surprised me how quiet this place was. Almost no sign of life, mussels or shrimps, probably because just 700 meter away is a dock for cruise ships which have most likely destroyed the ocean floor in this area with their powerful propellers.
Nevertheless the silence is as interesting in the ocean as the silence on open land, so it is worth listening to.
While I was recording, the ferry to Viðey came and went. So be careful, you need to lower the volume between 11 to 14 min because the propeller noise will be very loud .
You can get an idea how Bethowave 7121 hydrophones perform in this recording. It comes straight from the recorder. No noise reduction, just fade in and out and downgrade from 24/48 wav to 256 kbps mp3
