Dr. Michael Andrew Bigg was a Canadian marine biologist who is recognized as the founder of modern research on killer whales. With his colleagues, he developed new techniques for studying killer whales and conducted the first population census of the animals. Bigg's work in wildlife photo-identification enabled the longitudinal study of individual killer whales, their travel patterns, and their social relationships in the wild, and revolutionized the study of cetaceans.

Erich Hoyt is a whale and dolphin (cetacean) researcher, conservationist, lecturer and author of 22 books and more than 600 reports, articles and papers. His book Marine Protected Areas for Whales, Dolphins and Porpoises, has been widely reviewed as the "definitive reference of the current extent of cetacean ecosystems-based management" and as "a unique and essential book for anybody interested in the conservation and protection of cetaceans. [This] definitive source on MPAs marine protected areas for cetaceans…will influence the design and management of this important and rapidly developing conservation tool." Choice listed the book as an "Outstanding Academic Title’ for the year 2012. Since 2013, as Research Fellow with Whale and Dolphin Conservation (WDC) and IUCN SSC/WCPA Marine Mammal Protected Areas Task Force co-chair with Giuseppe Notarbartolo di Sciara, Hoyt has focussed on the creation and development of the new conservation tool of Important Marine Mammal Areas, or IMMAs. In 2016, following a MAVA Foundation pilot project to identify IMMAs in the Mediterranean, the Task Force's GOBI collaboration funded by the German Climate Initiative (IKI) began a six-year project to identify and implement IMMAs across most of the southern hemisphere. The IMMA tool has been received and widely endorsed by the Convention on Migratory Species (CMS), the Convention on Biological Diversity (CBD), various commissions within the International Union for Conservation of Nature (IUCN), the International Whaling Commission, as well as national governments and scientists.

Alexandra Bryant Hubbard Morton is best known for her 30-year study of wild killer whales in the Broughton Archipelago in British Columbia. Since the 1990s, her work has shifted toward the study of the impact of salmon farming on Canadian wild salmon.
