C27K was installed in 2016 as part of the temporary USArray project and integrated in 2020 into the permanent Alaska network as part of the National Science Foundation-sponsored Alaska Geophysics Arctic Observing Network project. Wildlife is a challenge: this station has suffered bear damage in the past. C27K is located near the 2018 M6.4 Kaktovik Earthquake fault zone. This site is located within the Arctic National Wildlife Refuge. C27K is generously hosted by our partners at the US Fish and Wildlife Service and the North Slope Borough.
