Rex Holwell, 47, pulls a sensor back into the SmartICE office after finishing a SmartKAMUTIK run to Natuashish, Newfoundland and Labrador, Canada, April 13, 2022. The SmartKAMUTIK uses electromagnetic sensors to measure the sea ice thickness and give northern communities real-time measurements of sea thickness along their ice "highways" through a website, downloadable phone app or Facebook. "We have to adapt to climate change," Holwell says. "We're going to need more tools like SmartICE." REUTERS/Melissa Renwick SEARCH "RENWICK SMARTICE" FOR THIS STORY.
