What does it take to study one of the ocean's most intelligent and elusive predators? Join marine biologist Filipa Samarra, Ph.D., founder of the Icelandic Orca Project, for an inside look at one of the longest-running studies of orcas. Discover how researchers identify individual whales, track their movements, study their diets and social relationships, and investigate the challenges they face. You'll also learn how participants on our new Earthwatch Expeditions adventure to Iceland work alongside Filipa's team, contributing to research that deepens our understanding of these highly social marine mammals.
