The NASA IceBridge Geometrics 823A Cesium Magnetometer L1B Time-Tagged Magnetic Field (IMGEO1B) data set contains magnetic field strength measurements taken over Antarctica using the Geometrics 823A Cesium Magnetometer.The data were collected by scientists working on the Investigating the Cryospheric Evolution of the Central Antarctic Plate (ICECAP) project, which is funded by the National Science Foundation (NSF) and the Natural Environment Research Council (NERC) with additional support from NASA Operation IceBridge. The data are stored in ASCII text format and are available via FTP for periodic, ongoing campaigns from 16 November 2009 to the present.
Operation IceBridge products may include test flight data that are not useful for research and scientific analysis. Test flights usually occur at the beginning of campaigns. Users should read flight reports for the flights that collected any of the data they intend to use. Check IceBridge campaign Flight Reports for dates and information about test flights.
Note on 2011 Antarctica data: On 02 May 2012, V01 2011 Antarctica data were replaced by V01.1. In V01.1, additional fields were added containing low-precision real-time position and orientation data resampled to match the times of the existing geophysical samples.
The directory structure for this data set is described in the 00README.txt file.
NASA Operation IceBridge supplements the Cryospheric Evolution of the Central Antarctic Plate (ICECAP) project with additional days of survey time. See the ICECAP Web page for more on the University of Texas ICECAP project.
Data are available via FTP.
