  1. 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. www.carisma.ca

  2. 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 2007-2009 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).
