Spying on Biodiversity Reuben Yost can count the eyelashes on a
Steller sea lion 50 miles away. Yost is monitoring a sea lion
rookery at Grand Point between Haines and Juneau, Alaska. One
route for a proposed highway up Lynn Canal passes by Grand Point
near the Katzehin River, and Yost is tracking sea lions'
seasonal occupation of the site for the Alaska Department of
Transportation. Reports from pilots flying over the rookery used
to be one of his best sources of information. These days, Yost
watches sea lions using a robotic solar- and wind- powered
camera system set up on the rocks. |Underwater camera: Fisheries

Department of Fish and Game "This morning I saw about 100
animals," he said. "We have three cameras there. One camera is
right on top looking down, and you can count the eyelashes on a
single animal with that one."
