Antarctic ice melt can change global ocean circulation, sediment cores suggest

A new study shows that during the last two deglaciations, i.e., the transition from an ice age to the warm interglacial periods, meltwater from the Antarctic ice sheet intensified stratification in the Southern Ocean. The results highlight the key role of the Antarctic ice sheet on ocean circulation and the regulation of the global climate. The study was led by François Fripiat, a researcher at the Max Planck Institute for Chemistry and the Univ…

How can Antarctic melt alter ocean circulation?

Sediment cores reveal Antarctic melt reshaped past ocean currents New paleoclimate evidence from deep sea sediment cores shows that large pulses of meltwater from Antarctica during the last two major ice sheet retreats coincided with major reorganizations of ocean circulation. Those cores preserve…
