Beluga Whale Call Methods

Submitted by afeltrin on Wed, 02/06/2019 - 15:49

We found two databases of marine mammal sounds, those being the Watkins Marine Mammal Sound Database through the New Bedford Whaling Museum, and the Macaulay Library through the Cornell Lab of Ornithology. We gathered approximately five sound files of Delphinapterus leucas (beluga whales) from each of the three locations we chose to analyze: St. Lawrence River and Saguenay River in Canada, and Harrison Bay in the north of Alaska. We downloaded each sound file and observed them in Raven Pro, paying attention to the peak frequency, note duration, and note rate. With the data gathered from Raven Pro, we then input the data into R Studio and observed the trends among the data, creating whisker box plots.
