NPEO 2011 Aircraft CTD-Chemistry Survey

 

The NPEO 2011 hydrographic survey consisted of ten 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, and 2010.

The first cast at the Barneo logistics camp/runway serves as a station close to 89°N and 180°Longitude.

Accumulated temperature and salinity profiles show the Historical Record of North Pole Hydrography since the 1950s.   Closely related projects are described at PSC Hydrographic Climatology and the Freshwater Switchyard of the Arctic Ocean.

Data from the NPEO aerial hydrographic and chemistry surveys are permanently archived at the Cooperative Arctic Data and Information Service (CADIS) and Arctic System Science (ARCSS) Data Archive.  These data plus certain preliminary data sets may be obtained via FTP at this website.
