Critical Atlantic Ocean currents kept going during last ice age, microfossils suggest

During the last ice age, the Atlantic Ocean's powerful current system remained active and continued to transport warm, salty water from the tropics to the North Atlantic despite extensive ice cover across much of the Northern Hemisphere, finds new research led by UCL scientists.

Critical Atlantic Ocean currents remained active during the last ice age

The study shows that deep ocean water in the North Atlantic was much warmer during the last ice age than scientists once believed.
