UrduThe release of more than 50 floating sensors, called Mobile Earthquake Recording in Marine Areas by Independent Divers (MERMAIDs), is increasing the number of seismic stations around the planet. Scientists will use them to clarify the picture of the massive mantel plume in the lower mantel lying below the South Pacific Ocean. This effort will also establish one of the most comprehensive overviews of seismic activity across the globe. Frederik Simons will discuss this international effort during the marine seismoacoustics session of the 178th ASA Meeting.

Stormquakes: Powerful Storms Cause Seafloor Tremors
Stormquakes are a recently discovered phenomenon characterized by seismic activity originating at the ocean floor due to powerful storms. Heavy storms, like hurricanes or nor’easters, can create seismic waves as large as magnitude 3.5 quakes. These tremors caused by the effects of storms on the seafloor are what researchers call stormquakes. Catherine de Groot-Hedlin, who was part of the group that first observed stormquakes, will discuss their properties and meteorological significance at the 178th ASA Meeting.
Fish Scattering Sound Waves Has Impact on Aquaculture
Fisheries acoustics have been studied for over 40 years to assess biomass and optimize aquaculture applications, and researchers in France have examined the phenomenon of how fish scatter acoustic waves in a dense school of fish contained in an open-sea cage. They developed an approach to help overcome issues encountered in aquaculture relating to the evaluation of the total biomass of dense schools of fish. They will discuss their work at the 178th ASA Meeting.
Finding Meaning in ‘Rick and Morty,’ One Burp at a Time
One of the first things viewers of “Rick and Morty” might notice about Rick is his penchant for punctuating his speech with burps. Brooke Kidner has analyzed the frequency and acoustics of belching while speaking, and by zeroing in on the specific pitches and sound qualities of a midspeech burp, aims to find what latent linguistic meaning might be found in the little-studied gastrointestinal grumbles. Kidner will present her findings at the 178th ASA Meeting.
Deployable Human-Scale Immersive Virtual Environments?
Combined with networks of sensors and controllers, Rensselaer Polytechnic Institute’s Collaborative Research Augmented Immersive Virtual Environment Laboratory Lab provides its users new modes of interactions between humans and virtual worlds, with experiences ranging from the familiar to the otherwise remote or downright imaginary.
National Park Service Scientists: Does Aircraft Noise Make Birds More Vocal?
National Park Service scientists analyzed nearly 1 million 10-second audio recording samples from national parks across the country and discovered a small increase in bird sound detection when an aircraft sound is also detected. During the 178th ASA Meeting, Kurt Fristrup will present the findings and how human responses to noise might be studied.
ASA, CDC Plan Revamp of Sound-Related Wikipedia Pages for International Year of Sound 2020
As harmful effects of noise are becoming more widely known, popular internet websites are increasingly being used as resources of information. For the International Year of Sound 2020 (#IYS2020), the Acoustical Society of America and the National Institute for Occupational Safety and Health, part of the CDC, took the lead in designing the online event Wiki4YearOfSound2020. The event will facilitate the improvement of Wikipedia content in topics related to acoustics, communication, music, noise and soundscapes.
Ultrasound Techniques Give Warning Signs of Preterm Births
Ultrasound can be used to examine cervix tissue and improve diagnostics, which is essential for predicting preterm births, and ultrasound data is used to compare two techniques for evaluating changes in cervical tissue throughout pregnancy. Researchers are looking at ultrasonic attenuation coefficients that can help scientists characterize cervical changes throughout pregnancy and in preparation for birth before other symptoms, such as contractions or dilation, occur. They will discuss their work at the 178th ASA Meeting.
