Research direction

Compare this experiment with #149 and the clone described in #173, focusing on the listed user_nl_mom, user_nl_cpl, user_nl_clm, user_nl_cam, and user_nl_cice settings. First verify the configuration and the MOM6 convection change referenced by PR #390. Done means determining whether reverting the ocean changes prevents the Lab Sea from freezing and reporting the run outcome.

Written by the indexing model from the issue text.

Description

Purpose:

Check if reverting all of the ocean changes back to the values used in 198 (#149) prevents the Lab Sea from freezing.

Description:
Clone of 217 #173, but with modified user_nl_mom (listed below). The only change that was not reverted was a bug fix in the convection scheme, described here.
