I've put the slides for my e-Biosphere 09 challenge entry on SlideShare. e-Biosphere '09 Challenge View more OpenOffice presentations from rdmpage. Not much information on the other entries yet, except for the eBiosphere Citizen Science Challenge, by Joel Sachs and colleagues, which will demonstrate a "global human sensor net". Their plan is to aggregate observations posted on Flickr, Twitter, Spotter, and email.
