Transport matrix method for ROMS

[trinefrisbaek]

Hi,
I am curious to know if anyone has experience generating transport matrices from ROMS? Khatiwala et al. (2005; https://doi.org/10.1016/j.ocemod.2004.04.002) and Khatiwala (2007; https://doi.org/10.1029/2007GB002923) has described a method for producing transport matrices that has been applied to the MITgcm but I am very curious to hear if anyone have worked on implementing this or a similar method for ROMS?
Thanks,
Trine
