Hi folks
Thanks Lia Mazzari for adding me to this wonderful group, thanks all for having me! Some really interesting discussions happening here.

I wanted to let you know about a feed that recently went live.

It’s part of an art commission I’m doing at Cody Dock on the lower tidal stretches of the River Lea in London. It’s a stereo pair of hydrophones I have installed just off the river bed (varying in submersion from almost out of the water to several meters deep, tide depending) The mics relay to an in-situ listening post riverside on the site, as well as in collaboration with Lia via this live stream on the locusonus network:

Hopefully will be running until mid/late May if things hold up!

Thanks Tom, this sounds interesting, just listening... very rich underwater soundscape. Can you tell a bit more about the microphones in use?
Here's the direct link to the stream: http://locus.creacast.com:9001/london_listen_to_the_lea.mp3

Thank you! Cheers for the direct link as well

thanks! Nice work, to have an open River listening post. How do people react? Will the stream also be scientifically analysed, species, activity etc.?

A rough drawing to illustrate the position. This is at very low tide. The blue line indicates roughly high tide. The soundscape varies a lot depending on the water level and the flow of the river. When the tide comes in the currents move in the opposite direction of the river flow

Do you mean that long sustained fizzy sound like right now?

Yes!

hm, fish would maybe move faster

That’s my thoughts as well

There are a number of above water sounds coming through too, eg crows, reversing bleeps, maybe a building site, planes. How close to the surface are the mics at the moment?

Yes absolutely Peter, I always find it so interesting the way these sounds penetrate the waters surface yet we cannot hear what’s happening beneath

Tom, can I switch/relay this stream to the radio.earth youtube channel for an hour or 2?

The colony of crows we hear often feed on the Asian Clams I mentioned

Interesting that crows (very smart, adaptable birds) have learnt to make a meal out a pretty invasive species.

It is isn’t it. They also have figured a way to actually get them open, I have watched them flying up and dropping them from a fair hight onto rocks/concrete to smash the shell!

Ok great stuff!

like they do with walnuts, have seen that quite often too. clever birds.

Ah yes nice

just read the Executive Summary, impressive. But seems that only numbers count for the "developers", like everywhere. Understandable, but dangerous. When they destroy something here, they promise something elsewhere. As if habitats and their inhabitants were exchangeable. That's the backside of the concept of "ecosystem services".

Sorry yes I was meaning to write “developers” we need a better word for that process

Thank you for the stream, this is very interesting... and with just a single photograph above invoked an entire world in my mind's eye/ear

Ah thank you Mace 🙏
