Update BGC and Icepack interfaces (#968)
Browse files Browse the repository at this point in the history 
Update Icepack to #05ac0ec3ea, CICE-Consortium/Icepack@05ac0ec which includes new BGC.

Deprecate skl BGC but leave code alone for now hoping we get help from the community to validate the latest code.

Update interfaces and bgc settings consistent with new version of Icepack BGC.

    icepack_aerosol.F90
        revised subroutine update_snow_bgc
    icepack_algae.F90
        revised subroutine zbio
        revised subroutine z_biogeochemistry
        revised subroutine algal_dyn
        add subroutine bgc_carbon_sum
    icepack_brine.F90
        revise subroutine prepare_hbrine
        revise subroutine update_hbrine
    icepack_mechred.F90
        add mbio calculation to subroutine ridge_shift
        add flux_bio calculation to subroutine ridge_ice
    icepack_therm_itd.F90
        update calculation of dvssl and dvint in subroutine lateral_melt
    icepack_zbgc.F90
        lots of stuff
    icepack_zbgc_shared.F90
        lots of stuff

Remove redundant arguments in non-BGC interfaces.

    icepack_atmo.F90
    icepack_fsd.F90
    icepack_isotope.F90
    icepack_itd.F90
    icepack_meltpond_topo.F90
    icepack_mushy_physics.F90
    icepack_snow.F90
    icepack_therm_bl99.F90
    icepack_therm_mushy.F90
    icepack_therm_shared.F90
    icepack_therm_vertical.F90
    icepack_tracers.F90
    icepack_wavefracspec.F90

Generalize merge_fluxes to make all arguments optional

Fix bug in subroutine snow_redist computation of hsn_new when nslyr=1

Update icepack_init_zbgc call.

Update bgc namelist defaults and settings in ice_in

Update testing, remove skl tests, add zaero tests.
