New visualisation of cross-slope properties in Antarctic margins? about asc_and_heat_transport HOT 7 OPEN

Oh, good to know about xwmb! I'm looking forward to Henri's upcoming COSIMA talk about it.

Love it! Would be great to apply this to u_along, temperature and density for temporal composites of months with strong or weak ASC.

Yep, it is easy enough to do with scalar tracer properties like temperature, and density, but u_along is harder. We would have to rotate the velocity vectors to be along- and across-slope for each isobath (the same isobaths as there are st_ocean values). I'm guessing this is an expensive code, considering we only have some selected isobaths for which u_along is available? The same applies for CSHT, by the way, with the added complexity of the zonal convergence term. I'm not sure how to handle u_along and CSHT, if there is any code that does this for multiple isobaths that would be great to see and incorporate.

I think for ACC speed we could just use u in these zonally averaged transect plots. It won't give values that match u_along, but it should still show when / where the ACC is strong/weak.

And maybe we can use CSHT to define the temporal composites (i.e. all the times when CSHT is southward), and then just show a schematic arrow for CSHT, but not actual data.

Cool! I'll try this! By the way, the xwmb package seems promising in quickly assessing transport across and along any given arbitrary section - might be faster than the methods we are currently using to calculate u_along and CSHT+ZC.

@taimoorsohail did you upload the code for this? I was going to make a new Figure 4 version using this method now, but am struggling to find the code.

Sorry @adele-morrison, I neglected to upload the relevant file before going on leave. I've uploaded it to my branch (taimoor) under the name "Circumpolar_average_example.ipynb". Let me know if you need any more help.
