Hydroacoustic Surveys

Hydroacoustic surveys involve using sound waves to explore and map underwater environments, such as oceans and lakes. Researchers send sound pulses from a boat or underwater device, which bounce off objects like fish, the seafloor, or underwater structures. By analyzing the returning echoes, scientists can gather information on fish populations, habitat types, and underwater topography. This technique is valuable for studying marine ecosystems, assessing fish stocks, and informing conservation efforts, providing insights that are often difficult to obtain through direct observation.
