A comparison of PMC-TOA & CTCRW and YAPS within a case study on smolt migrations. Here, YAPS consistently failed to fully converge and didn't return standard error values (i.e. no confidence ellipses).
A comparison of PMC-TOA and TDOA positioning applied to a smolt migration dataset. Positions are post processed with a Kalman filtered CTCRW model. Tag reflections resulted in incoherent tracks for TDOA positioning.
Satellite image of the study area where the case study data was collected and which the simulated study was based on. The fishpass and spillway are hard structures and likely culprits for causing the reflected tag transmissions detected across the receiver array.
New #FishSci #AcousticTelemetry positioning paper: PMC-TOA positioning.
I used adaptive importance sampling & mixture distributions to position fish in environments prone to tag reflections. Mixed with post-processing, this gives great tracks!
