Update: February 7, 2001
Come along with Cathy Beck and the Sirenia Project scientists for a new study in the Florida Everglades! Wild manatees are being captured, tagged and released for satellite tracking in this study. Join in their research today by tracking "Surfer", one of the first manatees already tagged for this study. Where was Surfer tagged and released? How far has she traveled so far? Does weather affect her migration in any way? -

More manatees were captured since our last report! Find out why, and who is the "greatest" among them. Grace's GPS tag was retrieved, but there are some missing location fixes...hmmm. Meanwhile, Surfer has swam north, but has she joined the other manatees? And is Nina really landlocked? Over at Blue Spring, things are "heating" up in the Run. And take a look at the "cold hard facts" that students sent in about manatees and cold water. - FINAL Manatee
