Educational Outreach '08
In 2008, we continued our educational outreach in cooperation with the
Mount Zion Progressive Baptist Church Summer Camp. In addition to our
two day computer laboratory based classroom modules, we added a day of data
gathering on the Eckerd College research boat. Our biggest challenge this
year, was the necessity of demonstrating proficient swimming skills in order
to ensure a safe experience for those participating in the boating component.
Scheduling of the annual maintenance of the boat and of the swimming pool
had to cooperate with the unpredictable timing of summer thunderstorms in
Florida. But miraculously, it all came together...

the data gathering phase of the research.

Following the swim test, students who demonstrated sufficient swimming
skills participated in field data gathering on Boca Ciega Bay. They
used two Canon EOS 2D digital cameras with 400mm image stabilized zoom
lenses to capture digital images of the dorsal fins of dolphins
sighted during the outing.

Following the boat trip, the two course modules of approximately two hours
each, were delivered to a group of approximately twelve students in a two
day sequence. The first module introduced basic image techniques and
a brief discussion of the underlying mathematics that makes it possible.
The second module in the sequence introduced material on the biological
aspects of the study of dolphins and included the use of the DARWIN
software to identify dolphins based on their dorsal fin outlines.

Overall the students seemed enthusiatic and engaged in the process, from data
gathering to image analysis.
