Data from: Behavioral responses of individual blue whales (Balaenoptera musculus) to mid-frequency military sonar
This study measured the degree of behavioral responses in blue whales (Balaenoptera musculus) to controlled noise exposure off the southern California coast. High-resolution movement and passive acoustic data were obtained from non-invasive archival tags (n=42) while surface positions were obtained...
