The Upgraded and Expanded CARISMA Magnetometer Array: Operations and New Science Ian R. Mann (PI), David K. Milling (PM), Andy Kale, I.J. Rae, Z.C. Kale, D. Wallis CARISMA Operations Team, Dept. of Physics, Univ. of Alberta.

 The original CARISMA component of the CGSM array prior to April 2005(the CANOPUS era) consisted of 13 NAROD S100 fluxgate magnetometers, returning data with a 5 second resolution, providing there was no interruption to the satellite connection. As a program of upgrades since then, the array has been updated to include local data logging capabilities to prevent data loss, improved connectivity using a high-speed satellite broadband internet link and return of data at the fluxgate magnetometers native rate (8 Hz) in real-time. As part of the upgrade, the array is also being expanded with the addition of 15 new sites, each containing a fluxgate magnetometer. Of the new sites 11 were installed during with 9 currently recording data.  In addition to the installation of the new sites, induction coil magnetometers—with a higher frequency response—have been deployed at 8 sites to complement the measurements of the fluxgate magnetometers. A each site—Dawson City, Fort Smith, Fort Churchill, Gillam, Island Lake, Ministik Lake, Pinawa and Thief River Falls—two coils were installed aligned with magnetic North and East (H and D).
