Short summary

We examined the thermal gradient as an index of the thermal field in the Atlantic. While the thermal anomaly in the South Atlantic should be equilibrated, the thermal disturbance in the North Atlantic causes thermal effects in the present day. Characteristics of the lithosphere ultimately determine the thermal field. The thermal gradient nonlinearly decreases with depth and varies significantly both laterally and with time, which has implications for methods of thermal history reconstruction.
