Smartfin

The Smartfin is a surfboard fin with sensors that measure important ocean properties that help researchers and coastal communities understand trends in ocean health. With the Smartfin, surfers become citizen scientists, turning wave sets into data sets simply while surfing their favorite breaks.

Researchers and scientists have been scrambling to obtain baseline information about changing ocean chemistry for the past several years, but collecting data in a nearshore environment like the surf zone with high-energy dynamics is not easy.  This challenge didn’t deter a few scientists and engineers, however, who recently developed a new tool to further this critical area of research.  Their tool? The Smartfin.

The Smartfin is a surfboard fin with sensors that measure multiple ocean parameters including temperature, location, and wave characteristics (sensors that measure salinity, pH, dissolved oxygen, and chlorophyll are in development).  Using an app on their phone, the data surfers acquire while in the water becomes accessible in near real-time to the world-wide scientific community. But Smartfin is not only about the data. It is also an effort to connect surfers and their communities to larger issues affecting ocean health. Using the data collected with Smartfin, we will be able to better understand trends in ocean warming and acidification and mobilize our communities to take action to combat these problems caused by climate change.  Learn more about Surfrider’s campaigns to address climate change.

Within the next couple of months, Smartfin will get its first public launch through distribution with the Surfrider Foundation’s San Diego chapter. But you don’t have to be a surfer to participate! In addition to collecting data (surfing) we’re recruiting people who can:

  • Represent Surfrider’s Smartfin committee at community events, beach cleanups, or demo days
  • Help write blogs or social media messages to help spread the word about ocean health in your community
  • Give presentations at local schools
  • Talk to your local elected representatives about ocean health issues
  • Plan events or fundraisers to support the Smartfin project

If you are in San Diego and interested in participating in the Smartfin program, you can sign-up with the San Diego chapter. If you are outside of the San Diego area, check out the “resources” tab on this page to learn how to start a Smartfin program in your area. 

Smartfin is an innovative collaboration with researchers at the Scripps Institution of Oceanography, one of the world’s leading institutions for oceanographic research; Lost Bird Project, an environmental arts organization that aims to inspire each of us to engage toward a better relationship with the earth; Surfrider Foundation; and Futures Fins, the world’s leading surfboard fin manufacturer.
