Despite all the “Waiting on Weather” and “Running Away from Weather,” the expedition recovered exciting new sedimentary climate records in the remote and notoriously stormy Southern Ocean.

Recovering ancient seafloor sediments requires complicated machinery and a skilled crew.
A scientist explains how she lines up wiggles on a screen to recover the missing layers in cores drilled from the bottom of the ocean.
It took six days to sail to Point Nemo, the most inaccessible point of the ocean on this planet, to drill a sample from the ocean floor.
What’s a bog corer? And how do seeds help scientists learn about the earth’s past? A paleoecologist explains the most important items in her toolkit.
Imbrie, a former head of the Department of Geological Sciences, helped confirmed connections between changes in Earth’s orbit and the timing of the ice ages and was a co-founder of CLIMAP, an international effort to use sediment cores to map Earth’s climate at the height of the last ice age.
“We had this magic key, this magic magnetic profile,” Pitman said. “We were able to date it and eventually use it not only as a tool that proved continental drift but a tool by which we could actually reconstruct the pattern of drift, that is the relative position of the continents, and the actual timing of the separation of the continents.”
