Scientists Discover Evidence of Long “Ocean Memory”

The data revealed that the deep Pacific Ocean is still cooling from a dip in global temperatures that chilled surface waters several centuries ago. Waters take so long to reach the depths of the Pacific that “they are still responding to the cooling trend that marked the entry into the Little Ice Age,” said first author Jake Gebbie at the Woods Hole Oceanographic Institution in Woods Hole, Mass. Scientists who measure ocean temperature trends will “take note of these results” and begin scouring their field measurements for these signals, said DeVries.
