Figure 17 illustrates the seasonal mean AT (°C) between the water depths of 20 and 1000 m, for a
bathymetry of 1000 m, across the Brazilian coastline. The black line represents a AT of 20 °C. It can be
observed that, for the regions A and B, the water depth in which the mean AT = 20 °C is achieved,
varies between 500 m in summer and 700-1000 m in other seasons. On the other hand, in the regions D
and C, a mean AT of 20 °C can be reached in a water depth of about 500-700 m throughout the year.
From a technical point of view, less structural challenges would be expected when bringing the cold
water from a depth of 500 m rather than from 1 km.

Figure 17. Seasonal (summer, autumn, winter, and spring) mean AT (°C) between 20 and 1000 m for
the bathymetry of 1000 m (for regions A, B, C and D) across the Brazilian coastline latitude considering
the period between January 1, 2007 and December 31, 2017. The black line corresponds to a AT of 20 °C.
