Spatial and temporal analysis of killer whale ( Orcinus orca) strandings in the North Pacific Ocean and the benefits of a coordinated stranding response protocol
Abstract Killer whales ( Orcinus orca ) are widely distributed throughout the world's oceans, yet little has been documented about their stranding patterns. Knowledge of stranding patterns improves our ability to examine and sample carcasses and provides a foundation for understanding killer wh...
