2001 NPEO CTD Survey via Twin Otter
 

The 2001 hydrographic survey consisted of nine stations, two between the North Pole and our deployment base at Canadian Forces Station (CFS) Alert, Nunavut, Canada, and the remainder along a section line from the Pole towards Alaska approximating a segment of the 1990's SCICEX transects.

Click on the Cast Number to view the temperature and salinity profiles in a separate window.

Casts 3, 4, and 5 were taken at the same locations as casts during the April 2000 survey, and temperature and salinity profiles one year apart are overlaid.

Cast 1 was only an equipment test. Cast 2 does not appear because it was taken at the 2001 deployment camp, approximately the same position as Cast 10 was taken five days later. The two casts are plotted together.

Vertical color contour sections of Salinity and Temperature along the green-colored line segnments between CTD stations are available.

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. An NPEO 2001 Chemistry Report (pdf ) is available.
