Shocking Crack in Ice Shelf Grows Another 11 Miles

Shocking Crack in Ice Shelf Grows Another 11 Miles

A 70-mile long crack in the Larsen C ice shelf grew another shocking 11 miles in December alone. That leaves just 12 miles before an iceberg the size of Delaware snaps off into the Southern Ocean.

"The Larsen C Ice shelf in Antarctica is primed to shed an area of more than 5000 square kilometers [approx. 3,100 square miles] following further substantial rift growth," wrote the Project MIDAS team, which has been studying the ice shelf.

"After a few months of steady, incremental advance since the last event, the rift grew suddenly by a further 18 kilometers [about 11 miles] during the second half of December 2016."

During the last Antarctic winter, the rift averaged about three miles per month of growth. In December, NASA released a set of images that found the crack measured 70 miles in length, 300 feet wide and one-third of a mile deep.

The sudden acceleration of the split in the ice has scientists convinced that a massive calving event is imminent.

"If it doesn't go in the next few months, I'll be amazed," Professor Adrian Luckman, project leader from Swansea University, told BBC News.

By itself, the iceberg that is set to break off won't lead to a rise in sea levels, as the ice shelf already floats on the ocean. However, the Larsen ice shelf acts as a buttress against continental glaciers that could then be free to slide into the sea. BBC reports that if all the ice that Larsen C holds back were released into the ocean, global waters would rise by 10 cm, or four inches.

Globally, sea levels have risen about eight inches since 1901. Its effects can be seen in increased flooding in South Florida, coastal erosion in Louisiana, intrusion of seawater into ground aquifers and stronger storm surges such as those seen in Superstorm Sandy.

Antarctica—which holds 90 percent of the Earth's fresh water—is losing about 92 billion tons of ice per year. The rate of loss has doubled from 2003 to 2014.

Long-term satellite observations show that Antarctic glaciers are rapidly retreating. A separate rift in the East Antarctic is forcing a British research station to relocate.

The Larsen C is the latest section of the huge ice shelf to break off. Larsen A collapsed in 1995. In 2002, Larsen B began to break apart. Within six weeks, a 1,235 square mile chunk of ice slipped away.

When the Larsen C ice shelf breaks off, it "will fundamentally change the landscape of the Antarctic Peninsula," said the U.K.-based Project MIDAS team.

Farmers are the stewards of our planet's precious soil, one of the least understood and untapped defenses against climate change. Because of its massive potential to store carbon and foundational role in growing our food supply, soil makes farming a solution for both climate change and food security.

The vast majority of SARS-CoV-2 transmission occurs indoors, most of it from the inhalation of airborne particles that contain the coronavirus. The best way to prevent the virus from spreading in a home or business would be to simply keep infected people away. But this is hard to do when an estimated 40% of cases are asymptomatic and asymptomatic people can still spread the coronavirus to others.

The tiny island nation of Mauritius, known for its turquoise waters, vibrant corals and diverse ecosystem, is in the midst of an environmental catastrophe after a Japanese cargo ship struck a reef off the country's coast two weeks ago. That ship, which is still intact, has since leaked more than 1,000 metric tons of oil into the Indian Ocean. Now, a greater threat looms, as a growing crack in the ship's hull might cause the ship to split in two and release the rest of the ship's oil into the water, NPR reported.

On Friday, Prime Minister Pravind Jugnauth declared a state of environmental emergency.

France has sent a military aircraft carrying pollution control equipment from the nearby island of Reunion to help mitigate the disaster. Additionally, Japan has sent a six-member team to assist as well, the BBC reported.

The teams are working to pump out the remaining oil from the ship, which was believed to be carrying 4,000 metric tons of fuel.

"We are expecting the worst," Mauritian Wildlife Foundation manager Jean Hugues Gardenne said on Monday, The Weather Channel reported. "The ship is showing really big, big cracks. We believe it will break into two at any time, at the maximum within two days. So much oil remains in the ship, so the disaster could become much worse. It's important to remove as much oil as possible. Helicopters are taking out the fuel little by little, ton by ton."

Sunil Dowarkasing, a former strategist for Greenpeace International and former member of parliament in Mauritius, told CNN that the ship contains three oil tanks. The one that ruptured has stopped leaking oil, giving disaster crews time to use a tanker and salvage teams to remove oil from the other two tanks before the ship splits.

By the end of Tuesday, the crew had removed over 1,000 metric tons of oil from the ship, NPR reported, leaving about 1,800 metric tons of oil and diesel, according to the company that owns the ship. So far the frantic efforts are paying off. Earlier today, a local police chief told BBC that there were still 700 metric tons aboard the ship.

The oil spill has already killed marine animals and turned the turquoise water black. It's also threatening the long-term viability of the country's coral reefs, lagoons and shoreline, NBC News reported.

"We are starting to see dead fish. We are starting to see animals like crabs covered in oil, we are starting to see seabirds covered in oil, including some which could not be rescued," said Vikash Tatayah, conservation director at Mauritius Wildlife Foundation, according to The Weather Channel.

While the Mauritian authorities have asked residents to leave the clean-up to officials, locals have organized to help.

"People have realized that they need to take things into their hands. We are here to protect our fauna and flora," environmental activist Ashok Subron said in an AFP story.

Reuters reported that sugar cane leaves, plastic bottles and human hair donated by locals are being sewn into makeshift booms.

Human hair absorbs oil, but not water, so scientists have long suggested it as a material to contain oil spills, Gizmodo reported. Mauritians are currently collecting as much human hair as possible to contribute to the booms, which consist of tubes and nets that float on the water to trap the oil.

There are trillions of microplastics in the ocean — they bob on the surface, float through the water column, and accumulate in clusters on the seafloor. With plastic being so ubiquitous, it's inevitable that marine organisms, such as sharks, will ingest them.
