Thanks. Looking again at the discussion thread it should have been clear to me that the functions used by MB-System are not changing.

With respect to time dependence, we certainly are doing repeated seafloor surveys that resolve both lateral and vertical deformation. For instance, on Axial seamount our repeated 1-m-scale bathymetry surveys show ~10-m wide fissures that opened coincident with the 2011 and 2015 eruptions, and annual repeat surveys are measuring the several tens of cm of uplift each year associated with the inflation of the subsurface magma reservoir. However, I’m not sure how having time dependence in Proj can tie into our representing or modeling this deformation. Any advice would be welcome.
