“Listening to the Ocean: Sound of Rain and Wind”

Abstract: Any sound produced in the ocean is confined between the ocean surface and the ocean floor and travels a great distance. The relationship between the underwater ecosystem and the composition of its sounds is called “ocean ambient noise” or “ocean soundscape” which reveals important information about the ocean environment, such as marine life, geological activities, natural phenomena, and the human footprint in the ocean. The complexity of the ocean environment makes it difficult to mathematically model ocean sound levels. Only accumulative data covering a long time period is useful in conducting a comprehensive ocean noise analysis. Most of the ocean noise datasets are scarce and limited to specific time periods and locations. However, today’s technologies allow us to capture the spatial and temporal dynamics of the ocean over a long period of time using a wide range of sensors. The Ocean Observatories Initiative (OOI) is a large-scale project that provides a unique observation of the ocean using more than 800 instruments including hydrophones which are recording ocean noise since 2015 in near real-time. In this talk, I use this unique and rich dataset to evaluate the contribution of rain and surface wind to the ocean noise. I use 3.5 years of acoustical and meteorological data recorded at the northeast Pacific Ocean to characterize and model the rain and wind noise received at both shallow and deep water.

Biography: Dr. Abadi obtained her Ph.D. in Mechanical Engineering at the University of Michigan in 2013, and a dual M.S. in Applied Mathematics and in Mechanical Engineering in 2010. She held a dual appointment as a Postdoctoral Research Scientist at Columbia University and as a Visiting Scientist at the University of Washington, School of Oceanography from 2013 to 2015. Her research primarily focuses on acoustical oceanography as it relates to wave propagation and energy interaction with the ocean bottom. Her interests range from underwater acoustics and array signal processing algorithms to assessing the impact of seismic activities on marine mammals, improving the resolution of acoustic images, and locating sound sources in ocean.

The UW Data Science Seminar is an annual lecture series at the University of Washington that hosts scholars working across applied areas of data science, such as the sciences, engineering, humanities and arts along with methodological areas in data science, such as computer science, applied math and statistics. Our presenters come from all domain fields and include occasional external speakers from regional partners, governmental agencies and industry.

All seminars will be hosted virtually for the 2020-2021 academic year, and are free and open to the public.
