Choice of isobath for cross-slope heat transport #8

Open adele-morrison opened 1 year ago

adele-morrison commented 1 year ago

Just occurred to me that picking the 1000m isobath to compute the heat transport across is another choice we've made in the analysis so far. Is the heat transport variability sensitive to using e.g. the 650m or 2000m isobath instead?

The plot shows the barotropic speed and some contours:

We decided to go with 700 m, 1000 m, 1500 m. These give a little spatial coverage without going too far on/offslope. If we find that the results vary a lot between the contours, we can still add more.

Closed as completed.

I realised there are already a bunch of pre-calculated contours (using Adele's continuous definition). We have 650m, 800m, 1000m, 1500m, 2500m. I won't recalculate them and suggest we use the 650m instead of the above suggested 700m contour.

Here some figures of the contours with speed as background: Fig_speed_bathymetry_contours_650m_1000m_1500m

The files are under /g/data/v45/akm157/model_data/access-om2/Antarctic_slope_contour_1000m.npz (replace the "1000m" with "650m" or "1500m").

Except I'm not sure I edited these to remove loops outside East Antarctica? I think these were probably for Ellen's project where we just focused on East Antarctica. Probably good to check if there are loops that need removing.

Oh, I see. I'll have a detailed look at the contours then.
