I recently did a comparison between some observed ocean climatology (from WOD) against ACCESS-OM2-01 for the same regions (within small polygons in the Weddell Sea, East Antarctic, and Bellingshausen Sea sectors). The surface ocean in the model was much fresher than the observation. I am trying to write (part of the discussion) why this might be. In the Kiss et al (2020) paper there is a mention that the high-resolution model drifts towards surface freshening and this is partly offset by salinity restoration (section 4).
I was trying to find out how much effect the salinity restoration has south of 50S, does it act to make the SSS fresher or saline?
Does the forcing (JRA55-do) have a role to play? or is it mixing parametrization?
If you know of a follow-up analysis or if you can share your thoughts on what prescribed or derived factors lead to the freshening, I would be happy to get some direction.
I originally tried sharing four figures with caption as a word document (it doesn’t take that format). I made it into a powerpoint (as it was an accepted format). It didn’t let me attach it. Finally I embedded individual figures, and it will only allow two figures. I think there’s so many rules to get by… I understand as a new post it may not be expecting multiple attachments etc, but is there a way to toggle with these controls?
No, I had not come across that dataset, since I am submitting my thesis soon, I worked with the WOD data that Will already had. But it is something to look into before I try to submit the manuscript at a later stage
Thank you for your comment in the slack channel and on my pretty figures
I am sharing the figures for Bellingshausen Sea and Weddell Sea here (as I could not attach them in the original post) In all three regions the surface (above the permanent pycnocline) is much fresher in the model than the respective observation profiles.
