Welcome to the home page of the Canadian Arctic Sea Ice Mass Balance Observatory
The Canadian Arctic Sea Ice Mass Balance Observatory or CASIMBO is a major sea ice research project conducted by the research group of Dr. Christian Haas at the University of Alberta. CASIMBO collaborates with numerous international institutions and projects (check out our links page).

Our research can be tied into four main themes:

    1. Sea Ice Thickness Variability

    2. Physical properties of snow and sea ice

    3. Remote sensing and validation

    4. Sea ice biology and biogeochemistry

  • A fox has chewed through a cable connecting one of the thermistor strings to the IMB.  Pictures are here.
  • A new CRREL Ice Mass Balance Buoy has been deployed near Grise Fjord, Nunavut. Buoy 300025010122530 was deployed by Eric Brossier on Jan 19, 2013.
  • Buoy 300234010735060 has  stopped transmitting data. Battery voltages dropped sharply in late March. The last transmission was April 2, 2012.
  • Preparations for CASIMBO 2012 continuing: Shipping equipment north in the next two weeks.
  • The Canister Buoy: 300234010118300 stopped transmitting data on February 10, 2012.
  • Preparations for CASIMBO 2012 are underway. Stay tuned for details.
  • Buoys 300234010730040 and 300234010737050 have left the Arctic Ocean and are heading south into Davis Strait.
  • Buoy 300234010118300 is frozen into the ice at the tip of Archer Fjord
  • Buoy 300234010731050 stopped transmitting data in mid-October but its sister buoy (300234010735050) is still reporting.
