• write_ocean_geometry_file (2.80s)
• modulo_around_point_ (0.05s)
• apply_topography_edits_from_file (0.03s)
• mom_calculate_grad_coriolis (0.03s)
• set_rotation_planetary (0.03s)
• initialize_grid_rotation_angle (0.02s)
• limit_topography (0.02s)

These probably aren't appropriate for porting but need to confirm.
