When the world's largest iceberg calved off Antarctica in early 2000, marine biologist Greg Stone and photographer Wes Skiles saw it as an invitation. As a team of scientists, explorers, sailors and a helicopter pilot, they set off to find and study this anomaly. "Of Penguins and Men and Ice Island" documents the expedition. With numb limbs, the team goes where no one has gone before, diving under the ice to find what giant melting icebergs mean for the planet. See the adventure at 7 tonight at UH-Manoa, Spalding Auditorium. 956-7633.

TRAIN IN VAIN

A TALK ON THE BIG ISLAND'S FORMER RAILROADS

With traffic congestion worsening all over the Islands, the Hawaiian Historical Society's slide-show presentation "Railroads of the Island of Hawai'i" at 7:30 tonight might shed old-time light on a modern problem. Big Island harbormaster and rail buff Ian Birnie, who used to ride the train down the Hamakua Coast, will talk about the island's train system — the most expensive one in the world in 1915. The program is in Mission Memorial Auditorium, 550 S. King St. in Honolulu.
