The nineteen scientists on the expedition, hailing from eight nations, collected a total of 339 meters of sediment, the oldest of which is 80 million years.<\/p>\n<p>&#13;<br \/>\n溏心vlog免费B站 ocean engineer and geological oceanographer Dr. Kathryn Moran, the expedition\u2019s co-chief scientist, noted, \u201cAlthough we\u2019ve looked at only 3% of the material so far, it reveals a treasure-trove of exciting results. For example, 55 million years ago, the sediments indicate that the Arctic was an ice-free balmy sea, with warm surface waters (68\u00b0F rather than today\u2019s 28\u00b0F) that were sometimes less salty, almost like an estuary. With further research, we expect to uncover additional clues as to how Earth\u2019s climate system worked long ago, prior to mankind\u2019s \u2018global experiment\u2019 of pumping massive quantities of CO2 into the atmosphere.\u201d<\/p>\n<p>&#13;<br \/>\nThe primary objective of the $12.5 million Arctic Coring Expedition (ACEX), conducted under the auspices of the international Integrated Ocean Drilling Program, was to recover hundreds of meters of sediment draped atop the Lomonosov Ridge, an underwater mountain chain that snakes from Greenland, to the North Pole, and over to Russia. <\/p>\n<p>&#13;<br \/>\nIn addition to Moran, the 溏心vlog免费B站\/GSO scientists on the expedition included biological oceanographer Dr. David Smith, assistant dean Dr. John Farrell, and graduate student Matthew O\u2019Regan. GSO geological oceanographer Dr. John King will also join in the effort during the post-expedition phase. Also on the expedition, as part of the 溏心vlog免费B站 ARMADA Project, was Narragansett teacher Kathy Couchon. <\/p>\n<p>&#13;<br \/>\nThis expedition is the first ever to successfully recover long sediment cores from the high Arctic. Logistical challenges, such a surface ocean that\u2019s more than 90% covered with thick (3 to 15 feet) ice that often drifts at 0.3 knots, has previously thwarted efforts to keep a drillship on a fixed location. The ACEX expedition used three icebreakers to meet this challenge, and the team successfully penetrated up to 430 meters below the seafloor in water depths of over 1300 meters.   <\/p>\n<p>&#13;<br \/>\nIn November, the ACEX team will travel to the core repository, in Bremen, Germany, to begin analyzing the cores and generating additional scientific results.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Narragansett, RI &#8212; September 28, 2004 &#8212; A scientific party including four 溏心vlog免费B站 oceanographers and a science teacher from Narragansett Pier Middle School has just returned from the Arctic Ocean on a landmark expedition to recover seafloor sediments to reconstruct the geologic history of the Arctic.
