Fall 2007 mother+calf localization
Synopsis and analysis of the mother-brother-calf encounter on September 1, 2007, in which we documented SRKW call exchange by localizing calls from the widely-separated individuals. The results were presented at the 2008 ASA meeting in Paris by Val Veirs via this PowerPoint presentation and this Flash-based animation in which the blue dot represents the calf's position and the red dot (initially off-screen) represents the mother and/or brother.
In December, 2018, we created a YouTube video version of the animation.
Need to add: Images of the relevant science logbook entry and field notes.
