How Fish Hear

Phragmites Adaptive Management Framework: Model Overview
Phragmites Adaptive Management Framework: Model OverviewThis animation is the third video in a series explaining different aspects of the Phragmites Adaptive Management Framework (PAMF). This video focuses on the machine learning model that PAMF uses to systematically learn from participant's data and then provide site-specific management guidance in return.

50 frame 3D reconstruction
Digital 3D reconstruction of lake bottom using 50 photo frames taken by the dive camera system. This example shows an arc since the sampling transect is a circle. This reconstruction allows us to gain more insight about the lake bottom since elevation has been added to the photographs.
