[juliasloan25]

Purpose

closes #334

To-do

Buildkite checks

• conservation checks (slabplanet)
  • slabplanet plots look identical to current main
• no singificant change to performance (build_history)
• reasonalble AMIP paperplot (note: there will be a small behavioral change in the AMIP run, but should be tiny.)
  • plots look identical to me (see below)

current main AMIP paperplot:

• I have read and checked the items on the review checklist.

LGTM. Since the plots look identical, it would be good to double check that the SIC is being now being updated (even if it's just an interactive check where you compare the SIC_init and SIC_current fields). Otherwise I think it's good to go!

[juliasloan25]

I've checked that SIC_current is getting updated and is different from SIC_init. I'll go ahead and rebase then merge if CI still looks good
