I'm just curious, why would it not be possible to do DNA tests? Is it too difficult to get to?
- _Microft 6y agoYes, this is taken from the paper: "Given the inherent complexity of obtaining physical samples (except for mobile fauna caught in baited traps) future studies could use environmental DNA (eDNA) techniques on water and sediment samples to identify taxa", https://www.frontiersin.org/articles/10.3389/fmars.2021.642040/full https://www.frontiersin.org/articles/10.3389/fmars.2021.6420...

- AnimalMuppet 6y agoBut you've already done the difficult part - you've drilled the hole, and brought samples back. Now you just need to bring back different samples. (And, I suppose, find a way to grab the right things...)
