Publication! (First author)
① Mayu Ogawa, Satoko S. Kimura. (2023). Variations in echolocation click characteristics of finless porpoise in response to day/night and absence/presence of vessel noise. PLOS ONE. https://doi.org/10.1371/journal.pone.0288513. (https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0288513)
We investigated the vocalization characteristics of finless porpoises inhabiting Japanese coastal waters, and examined how these characteristics vary between day and night and under the presence or absence of vessel noise.
② Mayu I. Ogawa, Satoko S. Kimura, Nozomu Ishiai, Tomonari Akamatsu. (2025). A hybrid method combining rule-based filter and machine learning to detect porpoise and vessel sounds from a pulse event recorder. Scientific Reports, 15. doi: 10.1038/s41598-025-16370-1.
We developed detectors for finless porpoise and vessel noise using A-tag data, a type of pulse event recorder.
③ Mayu Ogawa, Satoko S. Kimura. (2023). Measurements of wild finless porpoise (Neophocaena asiaeorientalis sunameri) on-axis burst-pulse sound. INTER-NOISE and NOISE-CON Congress and Conference Proceedings, InterNoise23, Chiba, Japan, 6866–6873(8). doi: 10.3397/IN_2023_1026.
The vocal characteristics of finless porpoise burst pulses were clarified for the first time in the wild.

About Me!
Growing up in Japan, Mayu Ogawa developed a fascination with dolphins after seeing a show at Hakkeijima Sea Paradise. This early curiosity led her to the Tokyo University of Marine Science and Technology, where hands-on training such as oceanographic observations deepened her interest in the marine environment. I later discovered ocean acoustics and became captivated by the possibility of using sound to uncover the hidden and mysterious underwater world.
Motivated by a desire to understand how human activities affect marine life, she pursued her doctoral studies at Kyoto University under Dr. Satoko S. Kimura, a specialist in passive acoustic monitoring of small cetaceans. There, I focused on the ecology and vocal behavior of narrow-ridged finless porpoises and investigated how vessel noise influences their presence and acoustic activity. I earned her Ph.D. in 2024.
I now explores a broad range of topics in ocean acoustics, from marine mammal and fish vocalizations to ocean soundscapes.
