Athens's main port was sealed for two hours yesterday to allow divers to install an underwater monitoring system as part of an Olympic security network that protesters contend is a privacy invasion.

The fiber-optic cables are a key element of an electronic web of cameras, sensors and other intelligence-gathering devices designed to help safeguard the Aug. 13-29 Olympics. Greece is spending $1.24 billion on Olympic security.

Although the devices are considered necessary for security, several groups said they will demonstrate against their use. Anti-globalization groups said they would protest outside Greece's parliament. Some political parties also have expressed concerns.

Police officials tried to reassure Athenians that the electronic monitoring system, which includes a blimp and thousands of infrared and high-resolution cameras, will not violate privacy.

The 200-foot blimp, which carries chemical "sniffers" and high resolution cameras, will start flying over the city this week, police said.

The underwater cables at the port of Piraeus will help secure an area that will host one of the world's largest gatherings of cruise ships during the Olympics.

McConneloug Wins Appeal

Mary McConneloug won her appeal to be nominated to the U.S. Olympic women's mountain biking team, overturning USA Cycling's selection of Sue Haywood and ending a bizarre process that will likely be remembered more for confusion than accomplishment.

The arbiter ruled that USA Cycling's decision to add 15 points to Haywood's international total -- a decision that pushed her one point ahead of McConneloug in a yearlong battle for the lone women's mountain start position allocated to the Americans for the Athens Games -- wasn't justified.

The ruling is binding, and McConneloug's name will formally be added to the official Olympic roster today.

Davis Makes British Team

American runner Malachi Davis was added to the British Olympic team, two weeks after receiving his British passport.

Davis was given provisional spots in the 400 meters and 4x400-meter relay for his adopted country.

Davis is from Sacramento but his mother was born in England. He decided to try for a place on the British team, figuring he had little chance to make the American squad.

"I'm extremely happy, I'm excited," Davis said. "It was definitely up in the air because I know there were quite a few athletes that still were part of the selection process."
