The subaquatic sounds of the tidal Thames starting from Princes Stairs in the Upper Pool and drifting down Limehouse Reach and onwards towards the Greenwich peninsula. 
On a falling tide, the sounds of the river will be streamed from hydrophones and a mobile streambox drifting, with me, in my kayak.
We will likely hear an ensemble of mechanical and industrial sound, the creaking of ropes and chains for example, with the possibilty of insect stridulation, gaseous events, and even mammalian and fish interjections. 
The early hour would suggest relatively less active marine traffic but, in reality, the river never sleeps. We may hear marine traffic on the move from their downstream, overnight moorings to upstream passenger embarkation points.

This link will take you to a previous ADrift commissioned for Thames21 in the summer of 2024.

For the livestream, my streambox comprises a Pi Zero and IQ Audio card with a 4G transmitter powered via a rechargeable Anker Li-ion battery. The components live in a waterproof case which will sit on the deck of my kayak.

Using an array of hydrophones I will dowse the sounds from beneath the waves as the city awakens.
