"The Yellowknife Seismic Array (YKA) has been an active part of Canada’s contribution to nuclear explosion monitoring for more than 50 years. Near continuous seismic monitoring of the globe has occurred at YKA for the telltale signs of nuclear explosion testing since its inception in 1962, resulting in thousands of tests being identified. To achieve such a track record, the array has undergone several upgrades to its technology and infrastructure to meet the demands of the time... This report documents many of the changes made to the array during the upgrade through a data comparison by both the upgraded YKA and its predecessor collected simultaneously during the latter half of 2013. The comparison verifies the data quality of the new array, its readiness for inclusion into full operational status, and outlines recommendations for minor improvements prior to its recertification and the decommissioning of the former YKA"--Abstract, page 3.
