Atlantic Behavioral Response Study (Atlantic BRS)

Welcome to the website of the Atlantic BRS!

This project involves field controlled exposure experiments (CEEs) to quantify the behavioral response of Cuvier’s beaked whales and short-finned pilot whales to tactical mid-frequency (3-4 kHz) active sonar (MFAS) off Cape Hatteras, North Carolina. The objective is to provide direct empirical measurements of behavioral response in relation to key exposure variables, including received exposure level, proximity to the source, and behavioral state.
