Study says artificial snow could stabilize melting West Antarctic Ice Sheet

A newly-published study presented the idea of ‘artificial snow’ could prevent further ice melting and could stop the West Antarctic Ice Sheet from sliding into the ocean. The scientists launched an engineering project to blanket the ice sheet’s surface.

The associated sea level rise of more than 3m would pose a serious challenge to highly populated areas including metropolises such as Calcutta, Shanghai, New York City, and Tokyo.

Specifically, the authors participating in the study aspire to see...

Possibility of future sea-level rise due to marine ice sheet instability in Antarctica

According to scientists, the Thwaites Glacier, which is as enormous as the size of Florida, is on the edge of melting so quickly that it could result to catastrophic global sea level rises. This glacier is one of five recently identified as unstable Antarctic glaciers, which have doubled their rate of ice loss in just six years.

In the worst-case scenario the ice from the Thwaites Glacier alone could raise global sea levels by as much as half a metre (20 inches) in as little as 150 years.

The...

The U.S. Coast Guard’s polar icebreaking fleet will remain based in Seattle after delivery of its new class of heavy icebreakers.

The first of a planned fleet of three heavy icebreakers, called Polar Security Cutters, is expected to deliver in 2023. The Coast Guard’s only working heavy icebreaker, USCGC Polar Star (WAGB-10), is based in Seattle. The Coast Guard also has one medium icebreaker, USCGC Healy (WAGB-20).

“I am pleased to...

Report to Congress on Coast Guard Polar Security Cutter

The following is the May 9, 2019 Congressional Research Service report, Coast Guard Polar Security Cutter (Polar
Icebreaker) Program: Background and Issues for Congress.

From the report

The Coast Guard Polar Security Cutter (PSC) program is a program to acquire three new heavy polar icebreakers, to be followed years from now by the acquisition of up to three new medium polar icebreakers. On April 23, 2019, the Coast Guard-Navy Integrated Program Office for the PSC program awarded a $745.9 million...

Document: Coast Guard Arctic Strategic Outlook

The following is the U.S. Coast Guard’s Arctic Strategic Outlook, released on April 22, 2019.

From the report

The United States is an Arctic Nation, and the United States Coast Guard has served as the lead federal agency for homeland security, safety, and environmental stewardship in the Arctic region for over 150 years. Since Revenue Cutters first sailed to Alaska in 1867 to establish U.S. sovereignty, the Service’s role has expanded, including representing American interests as a leader in the...

Unlike the other military services, the Coast Guard has not received budgetary relief to eliminate its maintenance backlog and keep cutters on patrol and helicopters flying or to address aging infrastructure problems pier-side, the commandant of the Coast Guard told a House panel on Tuesday.

While there has been money earmarked for...

SAN PEDRO, Calif. — As the Coast Guard continues modernizing with new cutters, drones and other technologies, its top leader warns the service will reach a “tipping point” without sufficient resources to support and sustain the force.

“Our missions have never been more relevant or demanding than today;...

The Coast Guard plans to award a contract this spring to build a new heavy icebreaker, but Commandant Adm. Karl Schultz says today’s problems running the one decades-old icebreaker illustrate the fragility of the current polar icebreaking capability.

Each year, USCGC Polar Star (WAGB-10) runs a critical mission of breaking through miles of...

Icebreaker crew faced shipboard fire, breakdowns on Antarctica mission

The crew of the Coast Guard icebreaker Polar Star fought fire that broke out in the ship’s incinerator compartment Feb. 10, the latest trouble to face the crew on their long deployments to Antarctica.

After expending four fire extinguishers trying to stop the fire, the crew needed two hours to put out the blaze. Damage from the fire was contained inside the incinerator, but several electrical systems and insulation nearby were damaged by firefighting water as the crew cooled down the incinerator...
