B-FROST on the cover of Planeur Info! 📰
A wonderful surprise for B-FROST: we are featured on the cover of issue 93 of Planeur Info, the official magazine of the French Gliding Federation (FFVP)! The cover highlights the “Ça plane pour tous” event, which B-FROST was delighted to take part in a day dedicated to inclusion and sharing, giving people with disabilities the opportunity to discover gliding and experience the unique sensation of flight. Being featured on the cover is a wonderful recognition of what we aim t

COMPASS: A New Course for B-FROST!
During summer 2026, B-FROST invited its members to take part in a consultation to help shape the future of the association and the projects that could define the years ahead. Polar exploration, underwater heritage, citizen science, sailing, inclusion… There were many possible directions! The feedback helped highlight a clear direction: giving the oceans a greater place in our future adventures. This is the spirit behind COMPASS, our multi-year programme for 2027, 2028 and bey

Reaching new heights, Together
On Sunday, September 6, B-FROST took part in a gliding discovery day dedicated to inclusion, sharing and adventure. Co-organised with Les Planeurs d’Ille-et-Vilaine at Saint-Sulpice-des-Landes airfield, the event was part of “Ça plane pour tous”, a nationwide initiative led by the French Gliding Federation (FFVP) on September 19 and 20. Adventure for everyone At B-FROST, we believe that adventure should not stop where disability begins. Several members of the association had

It’s Back-to-School Season at B-FROST! 🚀
After a first year filled with adventures, encounters and new projects, B-FROST is back for a new season. It’s a special moment: a chance to look back at how far we’ve come, but above all, to start charting what comes next. A First Year of Building A lot has happened since B-FROST was created. Projects have come to life, ideas have been tested, new encounters have opened up exciting possibilities and, most importantly, a community has gradually formed around one shared ambiti

B-FROST Is Taking a Summer Break… See You in September!
After several exciting months filled with exploration, new partnerships, and educational initiatives, the B-FROST team is taking a short summer break. Our first year has been an incredible journey. From participating in the NGWE2026 Greenland expedition to delivering educational outreach, expanding our network of partners, and laying the foundations for future exploration projects, we have achieved more than we could have imagined. This summer pause is an opportunity to recha

A Ground Penetrating Radar on the Greenland Ice Cap: Field Feedback from the ImpulseRadar CO4080
During the North Greenland Windsled Expedition 2026, the team used a particularly valuable scientific and safety tool: the ImpulseRadar CO4080, a ground penetrating radar designed to reveal what lies beneath the surface of snow and ice. At first glance, the Greenland ice cap can appear uniform. Yet beneath skis or snowmobiles, the terrain may hide weak zones, snow bridges, covered crevasses, or significant variations within the snow and ice layers. The purpose of ground penet

When a Book Connects Africa and Greenland
As part of the North Greenland Windsled Expedition 2026, we also wanted to highlight a remarkable work that, more than forty years after its publication, continues to build unexpected bridges between continents: An African in Greenland by Tété-Michel Kpomassie. This extraordinary travel memoir tells the story of a young man from Togo who set out to discover Greenland and the Inuit people, challenging conventional narratives of exploration. It offers a rare and inspiring persp

Sharing knowledge is part of the adventure
An expedition does not end when you return home. It continues through the stories you tell, the knowledge you share, and the inspiration you pass on to others. On June 30, 2026, Clotaire Berthelot, President of B-FROST, visited a Year 5 (CM2) class at Prat Foen Primary School in Guidel, Brittany, to share his experience from the North Greenland Windsled Expedition 2026, a scientific and exploratory journey across the Greenland Ice Sheet. For nearly two hours, the students wer

NGWE 2026: Lessons Learned from the Greenland Ice Sheet
After several weeks in Northwest Greenland, the North Greenland Windsled Expedition 2026 (NGWE 2026) has come to an end. Although we ultimately did not reach the East Coast as initially planned, the expedition achieved several important objectives and provided valuable insights for the future development of the Windsled concept. Reaching the Ice Sheet with Minimal External Support One of the primary goals of NGWE 2026 was to demonstrate that access to the Greenland Ice Sheet

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

🌬️ 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,
