D25K 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 multiple times. During one site visit, the field team discovered a smaller animal (possbly a wolverine) had damaged the borehole lid, resulting in a sensor frozen in the borehole. D25K is generously hosted by our partners at the Alaska Department of Natural Resources and the North Slope Borough.
