Graduate student, Derek Witt, deploys a broadband seismometer at Mile 216 of the Canol Road in the Mackenzie Mountains. This station will serve as one of the first ever broadband instruments in the heart of the Mackenzie Mountains. This station is part of a 40-instrument transect that runs from the NA-PA subduction zone, through the Mackenzie Mountains, to Great Bear Lake in the Slave Craton.
NOAA's National Geodetic Advisor for Alaska, Nic Kinsman, feels the earth move under her feet at Mendenhall Glacier in Juneau, Alaska. Many EarthScope PBO stations in Alaska are part of the Continually Operating Reference Station (CORS) network, a multi-purpose cooperative endeavor that allows surveyors, GIS users, engineers, scientists, and the public at large to use public NGS tools (such as OPUS) to obtain post-processed coordinates in alignment with the National Spatial Reference System.
