\u201cModels already exist to detect larger vessels\u201d in satellite images, Ricci explains, but \u201cas the object [that you want to detect] becomes smaller and smaller, it becomes harder.\u201d Most of the traffic in her study area is comprised of small, shallow-water, recreational boats, and the model she trained to detect them has opened up \u201ca dream list of projects\u201d that weren\u2019t possible before.<\/p>\n\n\n\n
Ultimately, Ricci will match time series information from both the satellite and the microphone data to compare fish activity in the absence or presence of (little to lots of) maritime traffic\u2013\u2013identifying how sound from boats in the Keys propagates through the water and how it impacts the behavior of the underwater wildlife. \u201cThe [region\u2019s] sanctuaries are trying to protect these natural environments,\u201d Ricci explains.

Ricci earned her master\u2019s degree at NC State studying underwater soundscapes<\/u><\/a> on the North Carolina coast. As a student in the Geospatial Analytics Ph.D. program<\/u><\/a>, she is weaving more remote sensing and data science into her research, to better understand how noise impacts underwater wildlife across space and time. \u201cIf you know how to ask questions, and how to analyze data, you can apply that to so many different fields,\u201d she says.<\/p>\n\n\n\n Ricci has a track record of detail-oriented problem-solving, a skill that has helped her to balance what she tweets about as #phdlife and #momlife.

Did you find them all?<\/em><\/p>\n","protected":false,"raw":"\n\n\n\n\n Close your eyes and you will probably find\u2013\u2013wherever you are\u2013\u2013that your surroundings are not completely silent. A co-worker is typing, birds are singing, a radio or TV is playing, a car is honking or rushing by, crickets are chirping\u2026<\/p>\n\n\n\n If you happened to be a fish cruising along the seafloor, your surroundings wouldn\u2019t be completely silent either. The ocean is full of natural sound\u2013\u2013from fish calling and bellowing, to dolphins and whales singing, to shrimp snapping their claws.<\/p>\n\n\n\n These undersea whistles, clicks and other sounds are the research purview of Geospatial Analytics Ph.D. student Shannon Ricci, an expert in underwater soundscapes. As part of her dissertation research, Ricci is developing new techniques to understand the impacts of boat traffic on natural sound beneath the sea.<\/p>\n\n\n\n Many studies have examined the effects of noise pollution on marine mammals\u2019 hearing and behavior, Ricci says, but far fewer have measured impacts on fish and other animals.<\/p>\n\n\n\n \u201cDo fish calls stop when a boat comes through?\u201d Ricci asks. And if so, \u201cwhat is the threshold of anthropogenic sound that we need to keep below, to reduce the impact on natural soundscapes?\u201d<\/p>\n\n\n\n To answer these questions, Ricci is analyzing data from protected areas in the Florida Keys, where the National Oceanic and Atmospheric Administration (NOAA) has set up microphones that continuously record underwater sound. With that audio, Ricci will be able to compile thirty-second snapshots of fish activity, time-stamped and linked to specific locations on the seafloor.<\/p>\n\n\n\n How will she know when a boat was near a microphone, and so whether it had the potential to impact fish behavior?<\/p>\n\n\n\n Public tracking data aren\u2019t available for the types of craft that frequent her study area, and so Ricci has developed a computer algorithm that can pick small boats out of satellite imagery.<\/p>\n\n\n\n \u201cModels already exist to detect larger vessels\u201d in satellite images, Ricci explains, but \u201cas the object [that you want to detect] becomes smaller and smaller, it becomes harder.\u201d Most of the traffic in her study area is comprised of small, shallow-water, recreational boats, and the model she trained to detect them has opened up \u201ca dream list of projects\u201d that weren\u2019t possible before.<\/p>\n\n\n\n Ultimately, Ricci will match time series information from both the satellite and the microphone data to compare fish activity in the absence or presence of (little to lots of) maritime traffic\u2013\u2013identifying how sound from boats in the Keys propagates through the water and how it impacts the behavior of the underwater wildlife. \u201cThe [region\u2019s] sanctuaries are trying to protect these natural environments,\u201d Ricci explains.
