Illustrating the Effects of Cold-Stunning on Sea Turtles

I'm proud to announce that an illustration depicting the physiological effects of cold-stunning in sea turtles, was recently awarded an honorable mention in the 2013 International Science and Engineering Visualization Challenge! The illustration, which was the result of a collaborative relationship between the National Aquarium and the Johns Hopkins Department of Art as Applied to Medicine, was drafted by student Katelyn McDonald.

The illustration depicts the physical and physiological (affecting the function of organs, tissues, and cells) effects of a cold stunning on sea turtles.

 Sea turtles are cold-blooded, meaning their body temperature relies on the temperature of their environment. Cold-stunning is essentially hypothermia (low body temperature) for sea turtles. Cold-stunning events in the northeast region cause chronic illnesses for turtles, which must undergo months of rehabilitation. While the turtles may not appear sick externally, the illustration demonstrates the multitude of internal illnesses and complications that result from chronic low body temperature.

A closer look at Katelyn's illustration of the effects cold-stunning have on sea turtles.

Founded in 1911, the Johns Hopkins Department of Art as Applied to Medicine was the first of its kind in the world. This intense two-year graduate program has trained medical illustrators to advance medical and scientific knowledge using illustration.

For more than 20 years, students from this program have worked with our Vice President of Biological Programs, Dr. Brent Whitaker, and staff as part of their training. The illustrations produced from this collaborative relationship have been published in books, journal articles, pamphlets, and training manuals and have been used for a variety of other purposes.

We’re excited that Science Magazine and the National Science Foundation have chosen the cold-stun piece as an Honorable Mention for the 2013 Visualization Challenge. Congratulations to Katelyn on this tremendous accomplishment!
