Phragmites Adaptive Management Framework: Model Overview
This 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.

10 frame 3D reconstruction
Digital 3D reconstruction of lake bottom using 10 photo frames taken by the dive camera system. This reconstruction allows us to gain more insight about the lake bottom since elevation has been added to the photographs.

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.

Playing with a Crayfish Before Sampling
Close up of crayfish next to center pivot. When crayfish swims away, then a diver can be seen next to the center pivot attaching the line for the dive camera transects.
