Development of Low-Cost, High Definition Videography Methods for Documenting Underwater Flora and Fauna and Creating Education Presentations


June 2016 - December 2018


Freshwater biotic communities are complex, magnificent ecosystems, but are usually unseen by the general public. In the southwestern United States, underwater views of these communities are almost never obtained. Until recently, methods for aquatic biologists and educators to communicate with the public about these systems required fish and other organisms be brought to the surface, or expensive underwater video and camera techniques be employed. However, with the accelerating development of new, inexpensive, high-definition underwater video technology and the advancement of personal computer systems to process such technology, ultra- high quality educational video presentations now lie within reach of biologists and educators to use to educate the public. We are developing inexpensive methods that can be used by most biologists and educators to produce stunning presentations of underwater viewscapes of freshwater systems. Methods were developed and tested while filming underwater aquatic communities of southern Nevada and California. Data are now being compiled, and methods will be presented in a thesis chapter and publication.
