Field notes
Lessons are described as short modules tracing cetacean evolution, biology, and conservation, with published research listed on a Sources page. The site says many lessons include real whale and dolphin recordings. A separate Deep Dive uses a 3,800-metre scroll to illustrate ocean depth, while the homepage explains the project’s name through the story of Luna, an orca from Nootka Sound.
