A research team from the Wildlife Conservation Society, the Quaternary Research Center, the Antarctic Chilean Institute and Universidad de Magallanes recently conducted an expedition to Admiralty Sound, located in South America's Tierra del Fuego, to survey the waterway's seal and bird populations.
Researchers succeeded in affixing satellite tags to southern elephant seals during the expedition. The tags enable conservationists to follow the movements of these marine mammals via satellite.
