Paleomagnetic projects in Alaska and NW Canada include many examples where Applied Paleomagnetics provided paleomagnetic services to petroleum and geotechnical companies since 1986. Our paleomagnetic projects on the North Slope of Alaska include extensive use of our paleomagnetic core orientation service in many North Slope oil fields, such as Prudhoe Bay, Kuparuk River, Endicott, Seal Island, NPRA, and ANWR, where we paleomagnetically oriented cores from the Lisburne, Kekiktuk, Sadlerochit, Shublik, Ivishak, and Kuparuk formations. Our paleomagnetic projects in Northwest Territories, Canada, focused on paleomagnetic orientation of natural fractures and in situ stress in cores from a Devonian reef at Norman Wells. Our paleomagnetic projects in southwest Alaska included paleomagnetic orientation of cores from the St. George, Navarin Basin, and North Aleutian Shelf COST wells, to constrain the accreted terrane history and structural dip. Our paleomagnetic projects in southeast Alaska consisted of paleomagnetic orientation of cores from the Yakutat well to constrain the accreted terrane history and for magnetostratigraphy. We conducted paleomagnetic studies in surface outcrops and subsurface cores on the North Slope of Alaska to measure changes in magnetic susceptibility, NRM intensity, and other magnetic properties caused by hydrocarbon migration during the Brooks Range orogeny. One goal of our paleomagnetic projects on the North Slope of Alaska was to detect vertical-axis tectonic rotation caused by opening of the Canada Basin. In east-central Alaska, we conducted paleomagnetic tectonic studies of the Tatonduk terrane, which is part of the 5% of Alaska thought to be autochthonous.
