Unmanned ship explores ocean
BY RICHARD C. LEWIS THE ASSOCIATED PRESS
PROVIDENCE, R.I. — The ship with all the gadgets and underwater rovers was stationed in the middle of the Atlantic Ocean, but for the first time, the scientists directing the expedition were not on board.
They sat in rooms thousands of miles away.
"We're treated like the chief scientist on the ship that makes the decision about it. It's just that we're not there," said Deborah Kelley, a geology professor at the University of Washington in Seattle and the expedition's co-leader.
The scientists and technicians, at universities in Rhode Island, Washington state and New Hampshire, watched 42-inch plasma television screens in awe as unmanned submersibles poked around the Lost City hydrothermal vents — a two football field- sized forest of limestone chimneys on the ocean floor.
Wearing headsets, the expedition's leaders stationed at the University of Washington told engineers on the ship where to send the robotic vehicles and its high-definition video cameras, and what to explore next.
Supporters said the trip, which ended Aug. 1, has broad implications for future exploration of the oceans, which cover about 70 percent of Earth but remain mostly unexplored. For one, it shows ships can stay out at sea for as many as eight months of the year, since the scientists no longer need to be on board.
"No scientist will sit on (a ship) for that long, reading a book and eating popcorn for
the whole time, no way," said Robert Ballard, the founder of the Titanic who's credited with dreaming up the technology used on the Lost City expedition.
A combination of technology helped pull off the feat. The expedition used fiber-optic cables, satellite feeds and a special, high-speed Internet connection to transmit images by the rowing submersibles' lights and cameras at Lost City within 1.5 seconds — essentially live — to the three "control" rooms.
The images broadcast to the land-based scientists were stunning, said Jeffrey Karson, a geology professor at Duke University and the expedition's coleader. Karson, who explored Lost City in dives in 2000 and 2003, said the two submersibles, one shining a bright light over a wide area and the other filming with a high definition camera, gave scientists a more panoramic view of the vent field.

Hydrothermal vents were first discovered by Ballard in 1977 near the Galapagos Islands in the Pacific. Those fields, called black smokers due to the color of the fluids released, are located around underwater volcanoes. But Lost City, discovered five years ago and nowhere near any undersea volcanoes, showed that vents could be found elsewhere. It's still the only vents of its kind found so far.
Lost City is a series of hydrothermal vents located at a northsouth underwater mountain chain called the Mid-Atlantic Ridge, which splits nearly the entire Atlantic Ocean. The site yields dramatic video because its limestone chimneys created by crystallized fluids can reach 200 feet in height.
Foul, furry stench afoot

The two girls, from Girard, III., attended the University of Illinois Extension's Stewardship Week at the Western Illinois Youth Camp on Lake Jacksonville, in Jacksonville, Ill. The skunk was part of the props for Scott Isringhausen, a site interpreter at Pere Marquette State Park and a native of Jerseyville, Ill., who took part in the environmental education workshop.

Two split $100,000 Wendy's reward
SAN FRANCISCO — A businessman will split a $100,000 reward from Wendy's International Inc. with an anonymous tipster for helping solve the infamous "chili finger" case, the company said yesterday.
Mike Casey, who runs an asphalt plant in Las Vegas that employed both the man who lost the finger and the husband of the woman who claimed she bit into the digit, had complained last week he hadn't been compensated for the tip that helped authorities unravel the scheme.
"I did what they wanted
and they offered it, so I think I have it coming," he said at the time.
Wendy's, based in Dublin, Ohio, said it was grateful to all the tipsters who called a hot line set up when profits plunged after reports of the hoax hit headlines worldwide.
"We sincerely thank these citizens for stepping forward and calling the special hot line number with information that helped investigators break open this case," Wendy's officials said in a statement.
Company officials said the second recipient asked to remain anonymous.
here to convey information, Mukherjee said. "Yes, I'm from a different country but I know I am capable."
Casey could not be reached by phone at work yesterday.

In fact, being overqualified is a common problem among GTAs. Mehmet Dakir is from Istanbul, Turkey, and received his doctorate in economics this month from the University.
Dalkir worked as a teaching assistant for two semesters in Turkey, three semesters in Australia and then as a GTA at the University for three years. He said teaching in the United States was a radically different experience from other countries.
"On the first day I started writing formulas for calculus on the board," Dalkir said. "The students started panicking."
Dalkir said high schools in Turkey and Australia were more strict and rigorous in their curriculums. Students must pass a written test to complete their education. He said the questions on the exam were comparable to what a junior in college should know.
"in Turkey and Australia, they make it hell for them in high school," Dalkir said. "But in the United States, high schools are more fun, and the undergraduate is harder. That's why it takes more experience and patience to teach here."
Metzler, a mathematics and physics major, has since taken multiple classes with international GTAs. He said the more he went to his teacher's office and spoke with them in a personal setting, he had no difficulties with the class or learning the material.
"I think students that complain about their teachers are looking for an excuse or probably are not holding up their end of the bargain," Metzler said.

Tobias said residents of Rieger Hall plan to write a letter to the parking department asking it to switch parking permits with the mens halls.
Jones said parking near Rieger Hall would ease safety concerns, and please residents.
Donna Hultine, director of KU parking, said the proposal could be considered by the parking commission as long as the spaces in the Union garage were used.
"I think it is a necessity to have lights to be safe but we still need to have parking closer to the hall," she said.

Board OKs teaching intelligent design
HARRISBURG, Pa. — A rural school board showed a clear bias against teaching evolution before it pushed through a plan to introduce "intelligent design" to students, a former board member testified yesterday in a trial over whether the concept has a place in public schools.
Aralene "Barrie" Callahan, who was once on the Dover school board and is now among the challengers, said she believed the policy to teach intelligent design was religion-based.Eight families are trying to remove the theory from Dover Area School District curriculum, arguing that it violates the constitutional separation of church and state. They say it effectively promotes the Bible's view of creation.The school district argues it is letting students know there are differences of opinion about evolution, not endorsing any religious view.
