Windsled Fully Assembled, Awaiting a Suitable Weather Window
Since arriving at Base Camp 2, most of our efforts have been focused on preparing the Windsled for the crossing of the Greenland Ice Sheet. After recovering the equipment stored during the 2025 campaign, we began the complete assembly of the system. The different modules were assembled and configured, including the steering module, cargo module, and living module. Once the structure was completed, we carried out technical checks and installed the equipment required for the ex

From the Shoreline to the Ice Cap: Entering the Expedition
For several days, our camp remained established at the foot of the glacier in northern Greenland. A silent, mineral landscape where time itself seemed suspended, marked only by field observations, route reconnaissance, and ongoing preparations. While waiting for the final administrative clearances required to continue our progression onto the Ice Cap, we used this time to assess the access routes on a daily basis. Conditions here evolve rapidly. The sun has been unusually str

At the Edge of the Ice Sheet
Since arriving in Upernavik last week, our days have been focused on preparations: equipment, food supplies, technical checks, and the implementation of scientific protocols.🧪 On Sunday, a first attempt to approach the glacier was interrupted by engine trouble on the hovercraft. Monday morning, repairs were carried out in wind and snowfall, followed by testing and a new departure. This time, the approach was a real success, and we were able to unload our equipment at the foo

Heading North: Departure for Upernavik
May 7th marks the true beginning of the North Greenland Windsled Expedition 2026. After months of preparation, logistical coordination, technical testing, and scientific planning, the team has now begun the journey north: Copenhagen, Nuuk, Ilulissat, and finally Upernavik, at the gateway to the High Arctic of Greenland. With every step of the journey, the inhabited world seems to fade a little further away. Infrastructure gradually disappears, giving way to the vast mineral a

🎯 NGWE2026 Preparation
As the departure for NGWE2026 approaches, preparation continues with a strong focus on safety and risk management in extreme environments. In this context, Clotaire Berthelot, President of B-FROST, recently completed the “Polar Environment” training delivered by IFREMMONT, a leading reference in its field. The training took place in Chamonix, both at the facilities of the École Nationale de Ski et d’Alpinisme and in the field at the Plan de l’Aiguille, combining theoretical k

🌬️ The wind as a common thread: B-FROST x Grain de Sail
The B-FROST association is pleased to announce the support of Grain de Sail for the North Greenland Windsled Expedition 2026. Beyond a partnership, this collaboration is built on a shared vision: bringing wind power back to the heart of low-carbon mobility. While Grain de Sail is helping to revive wind-powered maritime transport, the NGWE 2026 expedition follows the same approach. In spring 2026, an international team will cross northern Greenland aboard the Windsled, a sci

Preparing the science...
On March 3rd, 2026 , I had the opportunity to visit Georeva , the French representative of ImpulseRadar , to discover and test the Ground Penetrating Radar (GPR) system that will be used during the North Greenland Windsled Expedition 2026 (NGWE 2026) . This meeting marked an important step in the technical preparation of the expedition. Discovering the ground-penetrating radar During the visit, Franz Rhoemer presented the ImpulseRadar system in detail. It was a great opport

🌬️ When Wind Becomes a Scientific Tool – B-FROST Joins NGWE 2026
In spring 2026, the B-FROST association will take part in the North Greenland Windsled Expedition (NGWE 2026), a scientific traverse across northern Greenland aboard the Windsled, a polar sled powered solely by the force of the wind. Designed as a mobile research platform, the Windsled enables long-distance travel across the Greenland ice sheet with minimal environmental impact. In this extreme environment, scientific teams collect valuable data on snow, ice, and the climate

🌬️ The wind is rising…
Committed, ambitious projects exposed to extreme environments never follow a perfectly linear path. They evolve in the real world; dynamic, shifting, and sometimes unpredictable. In recent months, the external context has changed. Factors beyond our control have made the implementation of some of B-FROST’s key projects more complex. Adjustments were necessary. Decisions had to be made. Nothing unusual, ultimately, when working at the intersection of field operations, science,

✨ Merry Christmas from B-FROST ✨
On this Christmas Day, B-FROST wishes to celebrate what gives true meaning to adventure: sharing, connection, and openness to others. Exploring, creating, and passing things on is, above all, about moving forward together, learning from one another, and turning differences into a source of strength. Through every project, every action, and every story shared, we stand for an adventure that is accessible, human, and inclusive. Thank you to everyone who brings B-FROST to life,

🌍 The new B-FROST website is now live!
It is with great enthusiasm that we announce the launch of the brand-new B-FROST association website ❄️ After several weeks (and a few nights!) of reflection, writing, and building, this website marks an important milestone in the life of the association. It is designed to be both a showcase of our commitments, a space for sharing, and a gateway to our projects; whether related to exploration, science, culture, or inclusion. Why this website? This new site was conceived as a

🌊 B-FROST: early moral support that anchors our work in Brittany
B-FROST continues to grow, and an important milestone has just been reached: we have recently received moral support from several emblematic actors of our region; the Department of Morbihan , the Hénaff Group , the Arkema group, as well as label Lorient. These expressions of interest and encouragement strengthen our core ambition: to anchor B-FROST at the heart of the local ecosystem and to proudly carry the colors of our region in all our educational, scientific, and explo

❄️ B-FROST Becomes an Association: Turning Adventure into a Bridge Between Worlds
Originally born as a simple photography label, B-FROST is now evolving into a non-profit association dedicated to promoting adventure (in the broadest sense) as a vehicle for sharing, awareness, and inclusion. This transition reflects a strong commitment to connecting exploration, science, and culture, in order to encourage the transmission of knowledge, curiosity, cooperation, and social and cultural diversity, both locally and internationally. The B-FROST association is co
