Changing Ambient Noise Patterns in the Beaufort Sea
Description:
The Arctic Ocean is rapidly changing in response to global climate change forcings, leading to myriad impacts on the Arctic system, including its acoustic environment. As the Arctic warms, the seasonal patterns of the soundscape are disrupted, with changes to the thermohaline stratification of the water column, reduced summer sea ice extent, a transition in the morphology of sea ice toward more first-year ice, and increased exposure of the ocean to wave-generating winds. The changing ambient noise conditions in the Arctic Ocean affect ecosystems as well as our ability to use seismoacoustic data to detect acoustic sources of interest. The National Oceanic and Atmospheric Administration (NOAA) has established a hydroacoustic station in the Beaufort Sea as part of an effort to track ambient sound levels in United States waters. Records from this hydrophone contain information about geophysical, biological and anthropogenic phenomena contributing to the soundscape. In this project, we present progress toward mapping seasonal sound patterns recorded at this station and evaluating their impacts on detecting regional earthquakes recorded by the hydrophone.
