Within ISOSCAN, we aim to engage citizens and stakeholders to help collect snow samples over distances and durations we as scientists could never accomplish. During the tourism high season in winter, many tour operators in Tromsø run daily trips where they take groups for snowshoe hikes or to see Northern lights. Since they are on the road anyways, why not ask them to take a snow sample for ISOSCAN? And maybe even starting conversations about snow, weather, and climate science?
Being a tour guide is a tough job. You have responsibility for your group, many things to take care of, and long working days. If we ask a guide for sampling on top of that, the method must be reliable and simple. Importantly, the guides need to see that the sample is used, and what it’s being used for.
In November 2024 I went to Tromsø to make the case for ISOSCAN with the guides from Wandering Owl. Tour operator Wandering Owl had already been experimenting last season with citizen science snow sampling for us. My plan was now to showcase the ISOSCAN approach to the new guides for this year’s snow season and to encourage their further involvement.
It was amazing to witness how the room filled with energy as the guides arrived: about 30 people with diverse backgrounds, some experienced, some new to Tromsø, settled onto their chairs as the sound of many languages swirled in the air. Then I laid out what ISOSCAN involves and how snow sampling is useful. Finally, I talked about current weather forecasting, and why it’s hard to forecast clouds and snow – which is key when you want to take people snowshoeing or to see the Northern lights.

Participants showing interest and curiosity during the Q&A section
During the Q&A, an amazing show of interest and curiosity broke loose, friendly but direct. It became clear that yes, these stakeholders were engaged. And importantly, we agreed that Wondering Owl would do some ISOSCAN snow sampling with some of their tours. We’re excited to see the results from their sampling as the 2025 winter season ends!
