Tuesday April 20, 2004. The second day after the bus strike; first day I rode the bus.

The four buses I was on weren't any cleaner than before the strike. Maybe Metro Transit management didn't consider that important, in their campaign to lure back riders who'd been lost during the strike. Maybe they concentrated cleaning on those buses they figured reporters were likely to see; and/or buses which serve the more prosperous suburbs. Or maybe they're more interested in making statements about policies than in actually carrying them out.

Two of the drivers were grumpier than the pre-strike average; one was more cheerful and more helpful.

I traded in my expired 31-day pass for three seven-day passes, at Metro Transit's store in downtown Minneapolis. Picked up schedules for the buses I'm likely to ride at least occasionally.

Geology
New evidence supports three major glaciation events in the distant past
Glaciers reached Cape Cod, Massachusetts, in the most recent ice age about 20,000 years ago. But much harsher ice ages hit the Earth in an ancient geological interval known as "the Cryogenian Period" between 750 and 600 million years ago. A team of geologists from China and the United States now report evidence of at least three ice ages during that ancient time.

'Chuanming Zhou, a Virginia Tech geosciences post-doctoral associate, along with Xiao, Robert Tucker and Zhanxiong Peng of the Department of Earth and Planetary Sciences at Washington University of St. Louis, and Xunlai Yuan and Zhe Chen of Nanjing Institute of Geology and Paleontology, are co-authors of "New constraints on the ages of Neoproterozoic glaciations in South China," the cover story in the May 2004 issue Geology, the journal of the Geological Society of America.

'Geologists have studied glacial deposits from the Cryogenian Period for many years. In recent years, it has been hypothesized that the earth was covered with ice and the oceans frozen to a depth of one or two kilometers during Cryogenian glaciations--a scenario known as snowball Earth.

'"The implications are profound," says Xiao. "There would be no communication between the atmosphere and the ocean. The deep ocean would quickly become free of oxygen because light would not be able to penetrate the ice to fuel algae. Above the ice, there would be little rain or snow because there would be little evaporation. Many organisms that lived in milder conditions would become extinct."'
