NPEO 2003 Aircraft CTD Survey
 

The 2003 hydrographic survey consisted of eight stations. Casts 1 through 3 used the lightweight winch to measure profiles at camp Borneo, the Mooring deployment and recovery camp, and at the JCAD-6 deployment site west of Lomonosov Ridge. Casts 4 through 8 used the Twin Otter skiplane based at Alert to revisit the NPEO 2000 station positions between Ellesmere Island and the North Pole, including water sampling for chemistry.

The Historical Trend in North Pole Hydrography shows the changes in salinity and temperature profiles at the North Pole since 1950 and through the 1990s. 

Data from the NPEO aerial hydrographic and chemistry surveys are permanently archived at the Arctic System Science (ARCSS) Data Coordination Center. Currently available are CTD Profiles and Seawater Chemistry.  These data plus certain preliminary data sets may be obtained via FTP at this website.
