Start by comparing this case with issue #52 and inspect the linked case directory, user_nl_mom settings, diagnostics, and raw or CAM output paths. Done means determining whether the stated coefficient changes improve sea ice in both the Lab Sea and Southern Ocean, with the results recorded.

Purpose:
Check if reducing the GM/Redi coefficients improves sea ice in both the Lab Sea and the Southern Ocean.

Same as 133 (#52) except user_nl_mom is set to
