In order to make sure the deployment of O-Buoy 5 is successful, many different tests must be made. One of the tests conducted at CRREL is the cold test. CRREL has a two story cold room to allow the O-Buoy to be tested at temperatures as low as -20 Celsius in preparation for Arctic operations. The cold test is performed in horizontal and vertical positions to insure proper functionality. During this test, data from the carbon dioxide, ozone, and bromine oxide sensors are analyzed and adjustments made if necessary. Once the last connections have been made and tested, O-Buoy 5 will be crated and shipped to St. Johns Newfoundland were it will be loaded aboard the Canadian Icebreaker Louis S. St-Laurent.
