Implication

Observational acoustic study reveals a 50-dB ambient noise increase from orangemouth corvina, indicating unprecedented natural underwater sound amplification during breeding.

Key Points

Quantify seasonal fluctuations in ambient underwater noise levels and determine the biological origins of the observed acoustic variations.
Conducted monthly acoustic monitoring using a calibrated recording system from January to August 1970 in the Salton Sea, California.
Analyzed nighttime spectrum sound levels focused at a frequency of 1000 Hz.
Nighttime spectrum level at 1000 Hz surged by nearly 50 dB from January to May.
The acoustic elevation stemmed exclusively from chorusing by Cynoscion xanthulus (orangemouth corvina) during their seasonal breeding period.
The 50-dB rise represents the greatest sustained underwater ambient noise increase documented from natural origins.
