With final preparations done at McMurdo Station, the 2025-2026 NSF COLDEX field team is very close to deploying to our deep field site at the Allan Hills! Read more about what it’s taken them to get to this point.

The NSF COLDEX 2025-2026 field team has made it to McMurdo Station! After a week’s worth of travel, trainings, and delays, the team has finally arrived in Antarctica, where they have been settling in and putting the final touches on their field camp deployment.

NSF COLDEX is gearing up for another field season to Antarctica. This year, a team of our scientists and drillers are heading back to the Allan Hills, where ice as old as 6 million years has been found. Learn more about the area, the work we’ll be doing there, and who is going in our first 2025-2026 field season blog post!

Here are the last updates from our two 2024-2025 Antarctica field teams, which wrapped up their field work in January 2025. This last edition features words by Jeff Severinghaus, science team co-leader of the I-187 team, as well as Bridget Hall, science team member on the I-186 team, and various other members on that team.

Before the holidays, we received two updates from our field team: one from T.J. Fudge, Science Team Co-Leader for the I-187 Team and Research Associate Professor at the University of Washington, and one from Bridget Hall, Science Team member and Master’s student at the University of Minnesota.

After a few weeks of settling into Antarctica, getting used to the time zone differences, and finalizing equipment preparation, our first field team has finally made it to their field site: the Allan Hills.

The first wave of our 2024-2025 field team has successfully arrived at McMurdo Station. Over the last two weeks, members of the team have been catching up on and learning essential skills to ensure a successful deep field mission. They’ve learned to set up tents on ice, new knots for securing gear, and have been busy preparing their equipment before heading out onto the ice.

As the NSF COLDEX 2024-2025 team prepares for our third field season, we’re giving you a sneak peak at what they’ll be doing and a chance to meet the team.
