Arctic Ocean AXCTDs NPEO-IPY and Beyond
The National Science Foundation's International Polar Year (IPY) 2007-2008 Initiative supported the extension of the NPEO 2008 North Pole hydrographic survey to cover the Beaufort Sea by Twin Otter skiplane. Fifteen CTD-Chemistry surface stations were obtained in late March across the southern...
