Mean temperature in the upper, intermediate and deep waters were calculated for polygons for possible inclusion in multivariate analysis (Fig. 3.1.16). The polygons series show that the temperature in the upper, intermediate and deep waters in August–September 2019 were higher than the mean (1981–2010) in most subregions. The exceptions were the outer boundary subregions; the South West and the Franz Victoria Trough, where they were slightly below the mean. At Great Bank, the temperatures at bottom were in 2019 below the mean.
