Scientists use hovering zeppelin to film whales - Boston.com

"Scouting boats had tracked the orca pod, as the zeppelin floated aloft. Known as the southern resident killer whales, this group was designated as endangered in 2005. They live permanently in the Puget Sound, hunting salmon and other fish. Scientists for the National Oceanic and Atmospheric Administration mounted high definition cameras on the bottom of the zeppelin. A researcher for the Center for Whale Research also took pictures to calculate body measurements. Whales move at about 3 miles per hour, NOAA biologist Brad Hanson said, which made the zeppelin's hovering pace even more useful for observations. The researchers were able to observe about two dozen whales from the zeppelin. They watched the whales swim in tight groups, roll around each other and "spy hop," moving with their heads above water."
