Miksis-Olds' graduate research characterized the pattern of sound production from manatees and measured sound levels in grassbeds inhabited by manatees which revealed that, all else being equal, manatees opt for grassbeds with lower noise levels. Miksis-Olds' research determined that manatees increase their activity in the presence of sounds similar to boats and they alter their behavior with periods of higher sound levels connected to increased feeding activity. Miksis-Olds has used sound to track the location of marine mammals in the ocean. In the Arctic, Miksis-Olds developed and deployed low power sampling devices to provide data on the presence of whales and she has a decade-long data set tracking different species of marine mammals in the Bering Sea. Miksis-Olds has also used acoustic methods to track seals in the Bering Sea where she connected the presence or absence of seals with the amount of sea ice. Using hydrophone data from the
Preparatory Commission for the Comprehensive Nuclear Test Ban Treaty International Monitoring System, Miksis-Olds estimated the biodiversity in the near-field vicinity of three
hydrophones. The data are from hydrophones that are part of the system used for monitoring for nuclear explosions and
Susan Parks, Miksis-Olds, and Samuel Denes developed a metric that uses sound to assess biodiversity and found correlations between their metric and the number of whale calls around the hydrophones. and was part of a collaboration that identified an increase in sound levels in the Indian Ocean which can have a negative impact on marine mammals. During the
COVID-19 pandemic, Miksis-Olds and others have been expanding the global network of hydrophones that can track changes in ambient sound in the ocean. Miksis-Olds is leading the development of software that will allow researchers to share and analyze the data being generated by this network of hydrophones. == Awards and honors ==
