This cataloging project aims to study and record underwater sounds, specifically bioacoustic and anthropogenic sounds, at Pier 40 in the Hudson River. The project utilizes passive acoustic technologies, such as hydrophones, to capture and analyze the sounds made by marine organisms and human activities. The results provide valuable insights into the impact of these sounds on marine life and the overall ecosystem. The project is conducted under the guidance of mentors and supervisors.

KEY TERMS Hydrophone: a device which receives underwater sound waves and converts them into electric waves. Anthropogenic: referring to environmental alternations resulting from the presence or activities of humans. Bioacoustics: the study of the relation between living organisms and sound. Soniferous: sound making Spectrogram: a graph that plots frequency, time, and amplitude. Frequency Amplitude
Introduction • Only the uppermost layer receives sunlight so it is not easy for fish to see • Fish have poor eyesight • This leaves them to rely on senses other than sight. • One of these now vital senses is hearing
Intro continued Utilization of Sound and Hearing Navigation Mating Expressing aggression Feeding Communication
Frequency Number of waves passing a given point in a given amount of time Higher frequency, higher pitch Lower frequency, lower pitch Measured in hertz Amplitude The size of a wave passing a certain point The higher the amplitude, the higher the power The power is the amount of pressure generated by the amplitude Power is perceived as loudness Measured in decibels Intro continued
Intro continued Passive Acoustic Technologies • Technologies that enable us to listen to and record underwater sounds • Allows researchers to identify, record, and study underwater animals with the absence of visual information • Such technology has existed for decades, but has been recently put to new use
The Purpose To record and catalogue marine sounds in the Hudson River
Methods and Materials Water Quality Trapping Recording
Recording Some instruments used: • The hydrophone and headphones were both plugged into a cassette tape recorder • The hydrophone was submerged into water and then left under water for an hour, while recording • The recordings were uploaded, segmented, and then made into spectrograms • Duplicated segments were filtered, and/or amplified (if needed)

Conclusion • Many anthropogenic sounds and bioacoustics sound have been recorded as a range of frequency, instead of at one particular pitch • Higher amplitudes can not only confuse fish, but even change their behavior
