Mar Sem Fim (“Endless Sea” in English) is a Brazilian yacht that was shipwrecked, sunk and subsequently got frozen in ice in Maxwell Bay of Ardley Cove, Antarctica, about 1,200 kilometres south of the tip of South America, in April 7th, 2012.
The yacht that belonged to the famed Brazilian journalist and entrepreneur João Lara Mesquita, was manned by four crew who were filming a documentary off the Antarctic coast when the boat capsized.
Strong winds in excess of 100-kilometer per hour had tossed the boat from one side to the other “like a bucking bronco in a rodeo,” according to one crew member.
With their vessel trapped in ice, the crew radioed for help and was received by the Chilean navy in the base in Bahia Fildes, in Antarctica.
All four researchers were eventually rescued but bad weather delayed the process by two days.
João Lara Mesquita, who was also in the yacht, wrote in his blog:
“Then, with strong winds and high waves, the boat Frei came to us. Our evacuation was epic.
Waves of more than 1.5 meters and winds over 40 knots made the boat jump from one side to another, like a bucking bronco. When it got close, each of us … threw ourselves into the arms of three Chilean crew members. Fortunately all went safely.”
Call it a telescope, call it a detector, or call it an observatory – it’s all the same to the University of Wisconsin scientists at the IceCube, which is now the world’s largest neutrino research array.
The IceCube array consists of 86 identical holes, drilled 1.5 miles deep, scattered throughout the ice and filled with extremely sensitive particle physics monitoring equipment.
The IceCube is a tangential facility of the much larger Amundson-Scott South Pole Station, both of which are literally located at the South Pole in Antarctica, where temperatures are normally a deadly -75 degrees Fahrenheit.
The research being done at the IceCube is obscure and esoteric, as they essentially search for signs of tiny subatomic particles called neutrinos as they streak through the crystal clear ice thousands of feet below the surface, but its impact could be profound.
Neutrinos are one of the most mysterious building blocks of the universe, and while studying them is notoriously difficult, the more scientists understand about their behavior, the more they will be able to explain about how the universe works.
More heralded and easily understood than the science of the lab is remarkable engineering it took to create it. Beyond the extreme difficulties of travel and habitation at the South Pole, the drilling of the all-important holes used for the array’s sensors is an engineering marvel.
Using highly advanced equipment, scientists bored into the earth with an ultra-high-pressure hot water drill, not unlike a massive power washer.
Each tube took approximately 40 hours to drill in total.
Antarctica seems like a long way to go to measure one tiny particle, but the darkness and purity of the subsurface ice at the South Pole creates a naturally ideal environment for detecting neutrinos, which almost never actually interact with matter, making them very hard to measure.
