  <Quality>Missing data are indicated by '1.e35' in the data files. Data may be missing for an entire day, or for particular heights/depths. 

In 2002, the GPS units in both ice buoys failed. The position file included for 2002 (NPEO2002_icebuoys.pos) is from the weather station buoy 22207, which was deployed on the same floe.</Quality>

  <Summary>This data set contains ice temperature and mass balance data from drifting ice buoys near the North Pole in the Central Basin of the Arctic Ocean. Buoys were deployed each April by the Pacific Marine Environmental Laboratory (PMEL) and the Cold Regions Research and Engineering Laboratory (CRREL). The buoys drifted with the ice pack, and data were collected via satellite transmissions. Ice temperature data were collected year around during 2000-2003, at 10 cm depth intervals twice daily, every twelve hours.

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/).

Data are in tab-delimited ASCII text format. Data are distributed as a 170 KB compressed file available via FTP.</Summary>
