Interactive Graphics and 3D Models

Harmful algal blooms can be used to illustrate important concepts in biology, ecology, marine science, data analysis, and more. See below for materials that educators can incorporate into curriculum including interactive online resources as well as 3D model files of specific HAB species.

Algal Life Cycles

WHOI produced these interactive graphics to allow students to explore the life stages of several important HAB species:
