The Elizabeth River is one of the most polluted waterways in the country and the world’s first floating wetlands classroom–‘The Learning Barge’–is coming to her aid. Phoebe Crisman (University of Virginia) developed the floating field station, which is powered by solar and wind energy and utilizes recycled materials. The barge allows students to study and interact with the river’s marine ecosystem. Also Featured: Google Earth is an exciting new tool for archaeologists where high resolution aerial photographs are posted daily. Using similar technology, Dr. Walter Witschey (Longwood University) and other researchers are spotting ancient Maya roadways and city alignments for the first time. Suddenly accurate location information for thousands of archaeological sites is as close as an internet connection.
