The CEAREX sample position data include manned station and unmanned buoy drift position data. Also provided on the CEAREX CD-ROM are programs written in C programming language for use on a SUN workstation.
Information in this document has been derived from documentation files on NSIDC's CD-ROM titled Eastern Arctic Ice, Ocean and Atmosphere Data, Volume 1: CEAREX-1, version 1.0, 8/91.
For the manned camps (POLARBJORN Drift, Oceanography Camp, and Acoustics Camp), hourly listings of position and velocity were derived from a complex demodulation algorithm described in McPhee (1988). The results of complex demodulation for the buoys are not included.
