B. Kara, J. G. Richman, M. R. Carnes, C. N. Barron, H. E. Hurlburt, and T. Boyer (2012), Temperature versus salinity gradients below the ocean mixed layer, J. Geophys. Res., 117, CXXXXX, doi:10.1029/2011JC007382. Introduction The article 2011JC007382 contains figures representing climatological estimates only for the months of February, May, August, and November. While these characterize the extremes and the transition months of the seasonal cycle, the rests of the monthly estimates may also be of interest to readers. For completeness, all 12 months are provided in the supplemental material for the fields of mixed layer depth (MLD), MLD standard deviation, MLD noise sensitivity, isothermal gradient layer thickness (ITGLT), isohaline gradient layer thickness (IHGLT), compensation layer thickness (CLT), temperature and salinity control index (CI), and transition layer thickness (TLT). All fields are in the .pdf file 2011jc007382-txts01.pdf. Units, colors, and contour intervals are identical to the corresponding figures described in the article. These figures and the data used to create them are available for download indefinitely at the URL http://www7320.nrlssc.navy.mil/translayer. 1. 2011jc007382-txts01.pdf Text S1. Climatological estimates for all 12 months.
