Arctic Observing Network: Switchyard Region
The proposed research will document the circulation, variability, and driving mechanisms of the upper ocean in the “freshwater switchyard of the Arctic Ocean.” This unexplored region lies to the n
There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery. New evidence published this week in the leading journal Science shows for the first time that the ocean’s overturning circulation slowed during every one of those temperature plunges – at times almost stopping.
