We are in for a lot more events like this," said professor Ted Scambos, a glaciologist at the National Snow and Ice Data Center at the University of Colorado at Boulder. Scambos alerted the British Antarctic Survey after he noticed part of the Wilkins ice shelf disintegrating on February 28, when he was looking at NASA satellite images. Late February marks the end of summer at the South Pole and is the time when such events are most likely, he said. Watch aerial footage of the area » "The amazing thing was, we saw it within hours of it beginning, in between the morning and the afternoon pictures of that day," Scambos said of the large chunk that broke away on February 28. The Wilkins ice shelf lost about 6 percent of its surface a decade ago, the British Antarctic Survey said in a statement on its Web site Another 220 square miles -- including the chunk that Scambos spotted -- had splintered from the ice shelf as of March 8, the group said. Don't Miss Planet in peril Giant sea creatures found in Antarctic search U.N.: Glaciers shrinking at record rate "As of mid-March, only a narrow strip of shelf ice was protecting several thousand kilometers of potential further breakup," the group said. Scambos' center put the size of the threatened shelf at about 5,282 square miles, comparable to the state of Connecticut, or about half the area of Scotland. See a map and photos as the collapse progressed » Once Scambos called the British Antarctic Survey, the group sent an aircraft on a reconnaissance mission to examine the extent of the breakout. "We flew along the main crack and observed the sheer scale of movement from the breakage," said Jim Elliott, according to the group's Web site. "Big hefty chunks of ice, the size of small houses, look as though they've been thrown around like rubble -- it's like an explosion," he said. "Wilkins is the largest ice shelf on the Antarctic Peninsula yet to be threatened," David Vaughan of the British Antarctic Survey said, according to the Web site. "I didn't expect to see things happen this quickly. The ice shelf is hanging by a thread -- we'll know in the next few days or weeks what its fate will be." But with Antarctica's summer ending, Scambos said the "unusual show is over for this season." Ice shelves are floating ice sheets attached to the coast. Because they are already floating, their collapse does not have any effect on sea levels, according to the Cambridge-based British Antarctic Survey. Scambos said the ice shelf is not currently on the path of the increasingly popular tourist ships that travel from South America to Antarctica. But some plants and animals may have to adapt to the collapse. "Wildlife will be impacted, but they are pretty adept at dealing with a topsy-turvy world," he said. "The ecosystem is pretty resilient." Several ice shelves -- Prince Gustav Channel, Larsen Inlet, Larsen A, Larsen B, Wordie, Muller and Jones -- have collapsed in the past three decades, the British Antarctic Survey said. Larsen B, a 1,254-square-mile ice shelf, comparable in size to the U.S. state of Rhode Island, collapsed in 2002, the group said. Scientists say the western Antarctic peninsula -- the piece of the continent that stretches toward South America -- has warmed more than any other place on Earth over the past 50 years, rising by 0.9 degrees Fahrenheit each decade. Scambos said the poles will be the leading edge of what's happening in the rest of the world as global warming continues.

Dr. Abitia is the most caring teachers I have ever met. Every second of his lectures are interesting. Not only does his class prepare you outside of college but this class can change your life. There are very little homework assignments, reading, and projects. His tests are exactly what you cover in lecture. Take Abitia any chance you get. | |

Fred Abitia is simply an OUTSTANDING professor! The fellow who rated him poorly below is probably a flake and didn't listen in class. Abitia is very inspirational and motivational when he talks. He's an extremely successful entrepreneur in business. He has been with and has learned from the best. This guy shares his knowledge like a Jedi master sharing wisdom with his Jedi apprentice. The best professor at Cal Poly. | |

He was a great teacher although he was tough. He was genuinely interested in the success of his students and he took the opportunity to interact one on one whenever he could. His tests were tough, and sometimes a little tricky, but overall this professor was terrific. | |

Excellent class and instructor. Dr. Abitia has a great deal of experience that he is happy to share with you. He is a very successful businessman and wants all of his students to be just as successful. Test can be a little tricky and but there are a lot of old ones floating around. Make sure you find some to help you study. I suggest taking this class in your last or second to last quarter before graduating. Make sure you don't miss his lectures on interview and the hiring process--they are right on and will help you get the job you want. Lots of knowledge that helps in both your professional and personal life. I highly recommend this class and instructor. | |
