CICE6.1.2 is a minor update of CICE6.1.1 from March, 2020. It includes Icepack1.2.2. This and the Icepack tag include water isotopes as well as a couple of minor bug fixes that shouldn't affect science. This release updates the tx1 grid forcing dataset to JRA55, adds a couple of new namelist variables to improve model control, and contains several minor updates to scripts. Documentation has also been updated. Major changes: Added water isotopes as diagnostic tracers in Icepack #423 Bug fixes: Set max_blocks=1 instead of 0, only problematic in some atypical decompositions #431 Fix some general bugs in the IO implementation. These were not causing problems in standard configurations, but were detected with extended IO testing #444, #447 Enhancements: Update icepack to version 1.2.2 #460 Update tx1 test forcing to JRA55 #435 Add snow conductivity (ksno) into namelist #433 Add precision namelist to control real and double precision history files #446 Add conserv_check namelist to turn on internal conservation checks. This results in an abort if the internal check does not verify #450 Add ustar convergence control via a new atmiter_conv namelist variable #452 Upgrades for data assimilation using JEDI #427 Update HYCOM wind file forcing notation #425 Add some additional namelist checks and modify namelist checks abort message #459 Add ability to set compile cppdefs via ICE_CPPDEFS variable in the cice.settings file #448, #460 Improved test reporting for suites #428 Add pio testing on cheyenne leveraging prebuilt pio libraries #447 Remove old vector directives #453 (Note that this changed answers for cray compilers) Add code coverage testing capability #434, #436 Update test suite to improve coverage #447, #450 Migrate input data to zenodo #424 Machine updates including ports to hera intel, orion intel, cheyenne pgi, and cheyenne gnu #418, #424, #432, #438, #372, #447, #449, #460, #462 Documentation Update namelist tables including documentation of internal code defaults #459 Update documentation in general
