I’m currently working on similar problems, but trying to count all the fish in the sea using sonar and trawl catches ([really](https://archive.fisheries.noaa.gov/afsc/RACE/midwater/default_mw.php)). I’ve done a little hacking trying to implement the GMRF/SPDE approach in Julia, but haven’t got it working yet…I’d definitely be interested to hear updates as well.

@jbmuir I don’t know if you saw this [thread](https://discourse.julialang.org/t/implementing-sparse-gaussian-process-model-with-turing-and-stheno/46886), but I just managed to get a (slightly hacky) sparse Stheno GP to work inside a Turing model, which may be of use to you…if you’ve got thoughts about how this should work in a less-hacky way, there’s an open [issue](https://github.com/willtebbutt/Stheno.jl/issues/134) where it would be great to hear your input!
