Prince Edward Island

Staying in Malpeque with the Savidge family, we spent much of the days on the beach.

They hydrophone in PEI

The water was very warm and clear. Fishing boats often passed by heading for the harbour at Malpeque; they would be quite closer, approx. 700 meters offshore.

Burying the Hydrophone in the mud

We buried the hydrophone in the sand in several feet of water. People’s feet on the sandy bottom were quite audible. The sounds of them swishing the water with their legs or hands were diminished, but you could hear two separate sounds of waves: one high pitched, very present sound as the water moved over the hydrophone itself (even buried!), and the other as the waves moved on the shoreline. We did a test to see how far away the hydrophone would pick up someone thumping on the ground, and it was audible for over 50 meters.

Hydrophone is buried in the sand

We buried the hydrophone in several inches of sand on the shore and could hear people walking close by as dull thump-thumps. There were also great shwhishy crunchy munch sounds as we brushed, scooped and dropped sand around the hydrophone.

Singing in the water for the hydrophon

One willing participant put her face in the water and sang a song for the crabs.

At the campsite we could hear cicadas (track above). They were singing to each other in a huge chorus, but by the time I got my gear ready, only one was screeching solo.
