For those interested, I'm on tonight's live show at 7PM Pacific, 8 Mountain, and 10 Eastern talking about satellite tracking of whales. Calling in questions is encouraged! You can listen over the link or by phone (there’s no video feed of the guests) at
We use a software called OceanLens developed by Booz Allen Hamilton to of one humpback whale over 4 months. The data is from an experimental tag that shows the greatest depth reached between surfacing. The spreading pink object is the sound cloud radiated by a ship: 130 decibels right next to the ship, then spreading out and fading (this is at 2 KHz). Data courtesy of Dr. Ari Leanander: the ship was not in the original data and was added in to show how the interactions between cetaceans and sound can be mapped. I'm having some problems uploading it but will work on it.
