SEA Days: Whale Tales

Every month, the third Saturday is a special day at Birch Aquarium: SEA Days!

As the tagline suggests, SEA Days are always full of  “Science, Exploration, and Adventure.” Visitors and members can meet a Scripps Institution of Oceanography, UC San Diego scientist or other local researcher and get hands-on with science, participate in activity stations, and get creative with a thematic craft.

Why are Whale Acoustics important to study?

It’s important to study whale acoustics because it gives us insight into animals’ behavior, including feeding, social, and mating patterns.  We can also use acoustics to learn how animals use a particular area and we can examine diel and seasonal patterns to study how those patterns change in relation to climate patterns and anthropogenic (human-caused) impacts.  Ultimately, the data gleaned from our studies can be used to help advise conservation managers and policy makers.

How did you decide to work on this particular issue?

My curiosity of all-things-ocean began when I was little and fell in love with the ocean during family trips to the beach during summer vacation.  I’m motivated by the fact that there’s still so much to learn about whales and dolphins and the environment in which they live!

What is the most interesting thing you have learned while studying whale acoustics?

I find it interesting that we can attribute specific call types to individual whale and dolphin species and that each of those calls is used for a different purpose.  For example, minke whales make a variety of sounds including boings (Rankin & Barlow, 2005), pulse trains (Mellinger et al, 2000), star-wars vocalizations (Gedamke et al, 2001) and even a bio-duck call (Risch et al, 2014)!
