Travels with Kenji

Kenji Yoshikawa calls in adjustments to his permafrost outreach itinerary. Photo: Ned Rozell,

Permafrost troubadour Kenji Yoshikawa (University of Alaska) last week visited permafrost observatories in remote villages of Alaska. “In general weather was not great this spring especially Bristol Bay area,” Yoshikawa wrote to PFS’ Alaska support manager Marin Kuizenga. “I could not make some villages by the weather at this time.”

Kenji is a one-man Arctic Observing Network or AON, and he spends the summer in perpetual movement (or so it seems to us) servicing permafrost sites sprinkled all over the Arctic, and concentrated in Alaska. At each stop, he brings his permafrost knowledge to local residents.

Ned Rozell joined Yoshikawa last week. Ned wrote about the adventure and posted pictures to his AlaskaTracks Web site. Don’t miss his observations.

Yoshikawa also maintains a permafrost outreach site at This fun site is full of tidbits about the places he visits, amply peppered with pictures. Make sure you have time to enjoy this site when you visit, because it’s easy to linger in Kenji’s world. And of course, there’s Tunnelman. 

Yoshikawa’s grant from the National Science Foundation  funds the installation and maintenance of around 100 permafrost observatories around Alaska.  For each one, Yoshikawa drills into the permafrost and installs micro dataloggers with temperature sensors to measure air and permafrost temperatures on the hour. These observatories are located next to schools. Yoshikawa visits the schools, teaches students and instructors about his work and then trains them to download and analyze the data from his instruments.
