Evaluating Video Documentation as a Method for Monitoring Ecosystem Change

Malea Saul, Oceanography

The ability to conduct and communicate climate related environmental changes relies heavily on the tool used for documentation. A key benefit of video as a scientific tool can allow scientists to obtain uninterrupted documentation over all temporal scales that provide physical and structural evidence of change. We present a video system to be used for the acquisition of duel field of view angles and 360 degree mosaics that is easily deployed and compatible for use with both stationary and mobile data collection. The visual acquisition system focuses on providing physical change information for use in comparison of GIS-based change models. Along with the video system, we present the protocol for its use and results from preliminary tests focused on measuring the accuracy and precision of the system. Additionally, a case study of a nearshore habitat, a system that experiences a significant amount of change from different climate and environmental forces, was conducted. Completion of such a system allows scientists to use video to monitor and collect visual data regarding ecosystem change over temporal and spatial scales, and provides a communication tool for education and outreach purposes.
