[4] Benoit-Bird's research uses acoustical tools to study the interactions between predators and their prey in marine environments.

Key linkages characterized in the lab's research include simultaneous tracking of predator-prey pairs such as northern fur seals and their prey juvenile pollock,[5] spinner dolphins and micronekton,[6] fish and zooplankton in thin layers in Monterey Bay,[7] and beaked whales and squid.

[8] Benoit-Bird's research has also used acoustic measurements to examine how changes in the phase of the moon impact the migration of small marine organisms[9] and the ability of predators such as spinner and dusky dolphins to find their prey.

[10] In research conducted off California, Brandon Southall and Benoit-Bird determined that beaked whales prefer to forage within a Navy test range due to the high density of prey available to the peaked whales in that region.

[11] Benoit-Bird has also developed instrumentation to make acoustic measurements with submersibles[12] and autonomous vehicles.
