Overheated planet update: You know what icebreaker isn't sufficient for our warmist scientists in Antarctica? A 420-foot, 36 million-pound ship that can ram through 8 feet of ice and carry 1.2 million gallons of fossil fuel

Antarctic Research Upgrades Could Put Polar Science on Ice: Scientific American

The mounting cost of maintaining U.S. research operations in Antarctica is putting the squeeze on polar science, according to a new review by an independent panel commissioned by the White House. And solving the problem may require cutting science spending, at least temporarily.

The U.S. Antarctic Program, managed by the National Science Foundation, maintains three year-round stations on the southern continent and supports more than 50 field camps that spring up each summer, during the main Antarctic field season.

A separate budget problem: how to pay for a new U.S. icebreaker, a ship experts say is desperately needed. Augustine calls it "the elephant in the living room."

The current U.S. icebreaking fleet includes just one functional vessel, the Coast Guard cutter Healy. Designed and operated as a research ship, the Healy cannot break through the thickest ice...
The agency eventually managed to assuage Murmansk's concerns about its ship's ability to handle the thick ice near McMurdo, freeing the Ignatyuk to lead the next U.S. resupply cruise, after all.

When an unseasonably early storm hit Nome, Alaska, last November, it left the city's port inaccessible. Faced with the possibility that Nome could run out of fuel before spring thawed the ice blocking the port, the Coast Guard decided in early January to send its only working icebreaker, the Healy, to escort an oil tanker on an emergency fuel run.

Diesel-Powered Coast Guard Icebreaker - Diesel Power Magazine

[2010] The USCGC Healy (WAGB-20) is the United States' newest and most capable polar icebreaker. Thanks to its diesel-electric propulsion system, this ship is able to break through 5 1/2 feet of ice at 2.6 knots-continuously. Hotstart engine oil heaters keep the ship's operating temperatures constant when underway, and even while at port...
