Scripts for Monte Carlo simulation modeling echolocation click detection probability.
The starting point is:
monteTL_3D_clickmethod.m
Parameter choices are selected in:
clickmethod_settings.m
An example transmission loss profile (DT07B_8radial_3DTL.mat, 8 radials) is available upon request.
There are lots of additional layers of complexity that have not (yet?) been implemented here.
-
Depth:
Animals are assumed to be surface associated with a lognormal dive depth distribution. However, other options are possible including diving to a consistent depth, or to a specific altitude above the seafloor. Multiphase dive profiles are also possible (e.g. X% of time in descent, Y% of time at depth.) -
Group-based models:
Only click-based detection probability is implemented here for simplicity. Group models are fairly trivial to add. -
Beam pattern:
As stated in the code, the beam pattern calculations used here are from Zimmer 2011, piston model estimates. It would be nice to incorporate Jens Koblitz's recent modeling work.
