Arctic coring expedition continues to yield new clues
For the second time in as many months, the IODP Arctic Coring
Expedition (ACEX) is making news with new analysis of ocean-floor sediments. In the Aug. 10 issue of Nature, an article by several of the expedition scientists summarizes their findings: more evidence that the Arctic was extremely warm, ...
