Climatology showing the mean position of the buffer zone throughout the year is indicated by the yellow band and is based on an analysis of satellite SST and sub-surface temperature from 1994 to the end of last year. The blue lines indicate the maximum northerly (5%) and southerly extent (5%) of buffer pixels in any year. For the climatology the position of the buffer zone is estimated as the upper and lower 5% of buffer pixels in the current year is depicted by the red band. This may not reflect the optimal placement of the buffer zone, and is intended as a guide to the seasonal movements of the SBT habitat preferences. Scenario 1 is the 80:15:5 habitat division. The red stars show the location of the core zone in this climatology for the 1 to 5 month forecasts.
