Hello Nadia,

A forensic genetic challenge  exists when DNA is destroyed by processes used in manufacturing of derivative animal products, preventing law enforcement in identification of protected species.  Alternative methods such as lipid profiles or isotope analysis unique to certain species may be possible but require voucher specimens that may or may not be available and methods that have not been tested or peer reviewed. Examples below:

1. derivative products made from endangered shark squalene (eg. Liver oil capsules).
2. derivative products made from lion bone and tiger bone (eg. lion bone cake and tiger wine).
   
   This is a law enforcement issue and would like to discuss possible solutions. 

Hi Filippo, 

Nice to read your message. Have you thought of contacting anyone in the Bioscience department at UCL? In our group "the People and Nature Lab", a few PhD students (Ben and Jason) are working on ML methods for coral reef monitoring. Might be interesting to reach out to them. List of People at CBER.

Best, Aude

This is awesome - thanks for sharing Stephanie!! We actually were looking around for a low-cost video camera to augment an MPA monitoring project locally and this looks like a really great option!

Cheers, Liz

Thank you for sharing! Super interesting, as we don't see many underwater stereo cameras! We also use Blue Robotics components in our projects and have found them reliable and easy to work with. 

Hi Sol,

I think your concern is well placed.  The pros typically tow an array of hydrophones, in its simpler configuration it looks like a long fat rubber hose containing maybe a dozen transducers feeding their electrical signals to a recording unit back on the ship.  All this is done to reduce noise from the ship, from waves crashing, and flow noise.  The multiple transducers can also be electronically tuned to be directional so that it can be "pointed" away from a noise source (like the ship).

In your position, I would just try the simplest thing that could work, then fix the problems as they arise.  It could be you may need to be dead in the water while recording.  To address surface noise (slapping waves, wind), you could mount the hydromoth low down on a spar buoy, which you tow into position.

Best of luck, it sounds like an interesting project (c:

Hydromoths are great for the price but they do not have the most streamlined housing and audio quality won't be as good as something like a SoundTrap or really any recorder with a proper hydrophone and 16-bit +DAQ system.

If you can afford it, this is an excellent SoundTrap based towed autonomous system NOAA have been using. It might work towed behind an autonomous vehicle

Alternatively, if you can have something inside the vehicle, a simple tape recorder (e.g. Tascam DR40X) and hydrophone on cable  will provide excellent sound quality. You could also use something like a Raspberry Pi with audio focussed ADC hat to record but that would require a bit more programming. Even consider a standard AudioMoth and plug a proper hydrophone into the audio jack - this would still have a 12-bit ADC but would provide better sound quality than a hydromoth (hydrophones are more omnidirectional and there's no air filled causing reflections and attenuation)

Hi Eva, 

Me and my colleagues run a small NGO based on Yogyakarta in Indonesia, although our projects are spread around the country. One of our active project is working with the movement ecology of Sunda gharials in Berbak-Sembilang National Park. One of the other is for Malayan Giant Turtle conservation using one-plan approach, which we are planning to start in situ phase. We can't give you promise about anything, but are able to be the host organization and would love to talk the opportunity!

Cheers,

Love the idea for in-house gear/supplies! It can be SOO difficult to travel with batteries, electronics parts with airline regs, country policies, etc. and shipping recorders/trail cams/etc. gets VERY (prohibitively) pricey in some countries with customs and taxes. Would be great to have an in-country place to source that kind of equipment. 

Housing educational resources related to that tech (in the form of people, print materials, computer tutorials) in-house would be similarly awesome. Particularly/especially in local languages.   

Having in-country wet labs as well helps the eDNA/genetics folks, since sample import/export permitting can be (always seems to be?!) a nightmare, so if you can even just do PCR and/or extractions in-country that helps a ton. 

In terms of overall field-station-wishlist - honestly, just the promise of continued funding and staff. Every field station I've been to or worked at is in a constant search for enough money to get through the next month/year, because the funding comes in the establish a station but then not to maintain it long-term. It's not sexy for a wishlist per se, but boy is it over-looked and much-needed. 

@hikinghack from Dinalab would probably have lots of good insights on this! 

My suggestion would probably be a 3D printer and Solder Station with a stock of common components. With those two things you can solve most problems.
