The authors would like to thank the crew of the M/V Lite Weight - Captain Paul Weltzin and Deckhand John Martin - for their assistance in deploying and recovering the hydrophone array. We would also like to thank Dean Hawthorne for his assistance in acoustic localization. This project was made possible by funds from the National Park Foundation's Alaska Coastal Marine Grant program and the Marine Mammal Commission. Additional thanks to the reviewers for comments and feedback that improved the final version of this manuscript.

N2 - Source levels of harbor seal breeding vocalizations were estimated using a three-element planar hydrophone array near the Beardslee Islands in Glacier Bay National Park and Preserve, Alaska. The average source level for these calls was 144 dBRMS re 1 μPa at 1 m in the 40-500 Hz frequency band. Source level estimates ranged from 129 to 149 dBRMS re 1 μPa. Four call parameters, including minimum frequency, peak frequency, total duration, and pulse duration, were also measured. These measurements indicated that breeding vocalizations of harbor seals near the Beardslee Islands of Glacier Bay National Park are similar in duration (average total duration: 4.8 s, average pulse duration: 3.0 s) to previously reported values from other populations, but are 170-220 Hz lower in average minimum frequency (78 Hz).
