1. Unraveling the Communicative Properties of Surface Active Behaviors in Southern Residents Horace Liang Beam Reach: School of Marine Science and Sustainability June 3, 2009

2. Why Surface Active Behaviors Behavioral States –Traveling, Foraging, Resting, Socializing Are there meanings behind SABs? –Play or Irritation? Whale watching impacts

3. Main Questions Do certain discrete call-types occur that coincide with specific surface active behaviors? Does presence of boats or boat noise affect the SAB rate of killer whales?

4. Methods Behavioral Data –Spreadsheets –Binoculars –Watch and GPS Acoustic Data –Sound Devices –Hydrophone Array Monika Wieland’s 2007 Lime Kiln Data

5. (209)

6. Analysis Audacity 1.3.2 beta –Classified Discrete Call-types –Ford’s 1987 Catalog of Calls Microsoft Excel –Paired T-tests (Call-types in SABs) –ANOVA (Boat distance) –Linear Regression (SAB rates from noise)
