Sydney seals: From Manly to Malabar, marine life sprawls across a city

This came to me by way of my dad over the weekend, but it's is full of familiar names and has started popping up from other places in the conservation tech network. It's a gorgeous visual story via The Sydney Morning Herald, telling the tail of the return of fur seals in and around Sydney. It highlights PhD student Vanessa Morris' PhD research and the citizen science program Vanessa Pirotta created called Wild Sydney Harbour (www.wildsydneyharbour.com).

HydroMoth GroupGets campaign

It continues to be difficult to source microcontrollers due to global supply chain issues, but Open Acoustic Devices have managed to source a small supply for an initial group...

From Alex on Twitter:

Yes. The HydroMoth has the same microphone and firmware as the standard AudioMoth which is widely used for terrestrial conservation. You would need the standard green case which has a waterproof acoustic vent.

@Andrew_Hill Out of curiosity, since this campaign reached its goal & is ending soon, is it possible to turn the remaining Hydromoth units that didn't sell into Audiomoths for a limited GroupGets? I understand that Hydromoths can be used terrestrially as well, but they are more expensive than the last Audiomoth campaigns have been by $50+ so just wanted to see if Audiomoths would still be cheaper. Just trying to figure out if I should buy more Hydromoths or wait until Audiomoths start selling again (ends up being a trade-off between cost and time basically).

@Andrew_Hill I wonder if you could let us know more about the time keeping difference btw the regular AudioMoth and the HydroMoth (which is said to do better)?

Glad it was useful Steph.

We'll be leaving the survey open for as long as neccesary to build up a better idea of use-cases. So if any hydrophone users missed out you are more than welcome to add yours responses. We can then update the results later in the year.

Self-powered Buoy collecting vital sensor data -- Looking for conservation projects to collaborate with

Hey all! I work for a company called Sofar Ocean Technologies that is doing really cool work in the ocean conservation world and I'm interested in getting them to collaborate more...

Hello Aadithya,

Excited to hear about your marine acoustics outreach. I am interested to explore the possibilities of collaborative work on this line.

One of my doctoral scholars is about to submit his thesis on terrestrial acoustic studies. Please respond to [email protected] (as I may likely miss responses if any, send to this group). 

Regards

Jaishanker

Hi Jaishanker, I just reached out to over email, apologies for the delay. We are interested in working with underwater hydrophones and this might be of use in your specific case study. Bristlemouth's timeline is still being created, but we're hoping to have devkits ready closer to the end of this year. I'm happy to chat more to learn about the specific research you are doing and how we can best help!

If you're looking to identify collaborators - probably lots of organizations listed in the Conservation Tech Directory would be interested (quick prelim search yields orgs like Echospace, European Tracking Network, FACT network, IMOS, IOOS, other tracking networks like that, USA's NEON, eOceans, Oceans+)! Also org's like Blue Ventures, Save our Seas (run acoustic tracking array), MBON (run Biotrack) come to mind.

Hi @carlybatist !
Thanks a lot for the recommendations!

Hi Evelina - I would be interested in discussing this.  I work with dolphin acoustics in the Chesapeake Bay, which is a particulalry challenging noise environment.  Happy to try something new!

Cheers,

Robert

Hi @cosmicspittle !
Thank you for your interest to our technology! I sent you a private message to continue the discussion.

Hi @Rob+Appleby !

The implementation in the Vectronic camera collar is purely store on board - no transmission.

I believe they simply stuck one of the Foxeer action ("Box") cameras inside and wakes it up and triggers it according to the camera schedule uoloaded to the collar (still and video options). 

RunCam is another manufacturer of FPV and action cameras which might be interesting for you.

Cheers,

Lars

 

Hi Lars,

I have a colleague that's successfully used the Mobius cam system (https://www.mobius-actioncam.com/) for camera collars as well. RC cams are popular choice it seems. I have been attempting to tweak cheaper 'cube' cameras (e.g. https://tinyurl.com/w72kh77r) to do a similar job. I am using a bit of Frankestein's monster array of small control boards, including an Adafruit low power timer (https://www.adafruit.com/product/3573) and a SparkFun pro mini (https://www.sparkfun.com/products/11113). I am using an SMD transistor as a switch to control power, and another could be added to control settings if needed. Hoping to do a tutorial on it at some point in case there's any interest. 

Cheers,

Rob

Would certainly be cool to see a tutorial on this! Looking forward to that!

Hi Mauman. 

Did you have a specific application in mind? There are quite a few IoT systems but they all need to be pieced together. If there's a specific application context, I think it'd be an interesting discussion to have though.
