This $466,244 federal Project Grant award from the National Science Foundation's (NSF) Directorate for Engineering (CFDA 47.041) supports research on Passive Localized Underwater Transiting Observing Systems (PLUTOS) at Portland State University in Oregon. The project aims to study the links between underwater sound and marine biology, using low-cost drifting autonomous loggers to detect and analyze the soundscape, environmental DNA, and other environmental data to provide insights into the spatial and temporal variability of coastal ecosystems, food webs, and the abundance and distribution of organisms like seals, fish, and copepods. Key activities include adapting a low-cost drifter system, developing compact and low-cost in-situ environmental DNA sensors, and applying new approaches for directional soundscape processing and machine learning to localize and estimate the density of marine populations. The project is expected to run from October 2023 to September 2026.
