The level of noise pollution in the oceans has increased dramatically the last 50 years. As shipping traffic increases and ships get bigger and noisier, ocean noise is becoming a larger issue within NOAA\'s sanctuaries.

Many marine organisms, including marine mammals, sea turtles, fish and invertebrates, rely on sound and hearing for their survival. Over the last century, increases in human activity within our ocean have led to increasing levels of noise. This increasing amount of noise from human sources is a rising concern for the health and well-being of marine organisms and ecosystems. In this episode, we talk with NOAA marine ecologist Dr. Leila Hatch about her work to better understand the ocean soundscape by developing programs that can establish baselines, detect changes in noise levels, and support the design of methods to reduce noise impacts.
