Scientists warn of lost decade as Trump administration abandons unique icebreaker

When the U.S. launched the RVIB Nathaniel B. Palmer in 1992, it was hailed as the ship that would keep American science at the edge of the ice. Now, more than three decades later, that red-and-white vessel is headed for retirement, and researchers say the timing could not be worse.

The National Science Foundation (NSF) confirmed it will terminate the lease on the Palmer, its only Antarctic research icebreaker, while also pausing plans for a new ship. No other U.S. vessel can fully replace it.

Why does Antarctica need a research icebreaker?

Satellites can track ice loss from above, but many of the most important measurements come from below the surface, in places where only a hardened icebreaker can go. The Palmer has carried scientists close to Thwaites Glacier, ominously nicknamed the “Doomsday Glacier,” where warm waters threaten to destabilize ice sheets that could drive 10 feet of sea-level rise over time.

“In order to understand mass change, we need to be at the margin of the ice, where ice and ocean meet,” said Julia Wellner, a University of Houston marine geologist, speaking to NBC News. “And that is obtained by going on this ship.”

What happens if the U.S. pulls back from Antarctica?

As my title stated, researchers fear a “lost decade” of data. The NSF ended the charter of another vessel, the RV Laurence M. Gould, last year. That leaves only commercial ships or foreign partners as stopgaps. “Are we really going to depend on other countries to collect the observations we need to know how sea level is changing in the United States?” asked Carlos Moffat, an oceanographer at the University of Delaware.

Meanwhile, as we’ve seen in other aspects of global society, China and Russia are ramping up polar investment, adding new icebreakers and expanding their presence on the continent. For U.S. scientists, the Palmer’s retirement isn’t just a research setback but a geopolitical retreat.

A replacement had been tentatively planned, with $61 million allocated for early design work and a $1.2 billion price tag projected. But the NSF has “paused” the project. More than 170 scientists have signed petitions urging a reversal.

For now, the Palmer – named after a 19th-century seal hunter who first mapped parts of Antarctica – will be returned to its Louisiana-based owner. Without it, the U.S. faces the prospect of watching one of the planet’s fastest-changing frontiers from afar, just when the view from the ice matters most.
