2012 CTD Survey

The NPEO 2012 hydrographic survey consisted of fourteen stations, measuring a CTD transect from the Pole along 180° and along 90°East Longitudes as far as logistically feasible. Twin Otter stations recorded by the associated project Freshwater Switchyard of the Arctic Ocean in May 2011 added an additional line between the Pole and Alert. Similar sections were recorded during NPEO 2001, 2004, 2006, 2008, 2010, and 2011.

Two casts were recorded at at the Borneo logistics camp/runway.
