This data set includes diverse measurements of seawater chemistry along with supplementary conductivity, temperature, depth (CTD); pressure; salinity; potential temperature; and density data from the Arctic Ocean near the North Pole. Measurements were taken from sea ice platforms each April or May from 2000-2005. Investigators used a CTD-O₂ system to measure seawater conductivity, temperature, depth, and dissolved oxygen content, and collected Niskin bottle samples for measurements of salinity, oxygen isotope composition, and concentrations of phosphate, silicic acid, nitrate, nitrite, ammonium, and barium. The available in situ dissolved oxygen measurements were collected beginning in 2002.

The North Pole Environmental Observatory (NPEO) is a year-round, automated scientific observatory, deploying various instruments each April in order to learn how the world's northernmost sea helps regulate global climate. It consists of a set of unmanned scientific platforms that record oceanographic, cryospheric, and atmospheric data throughout the year. More information about the project is available at the project Web site, North Pole Environmental Observatory (http://psc.apl.washington.edu/northpole/).

These data are available via FTP.
