Interactive Models

Phytoplankton Distribution and Watersheds


Using interactive maps of chlorophyll concentration, students will identify patterns to describe the relationship between phytoplankton and watersheds. 

This interactive model is one of a three-part sequence of learning experiences related to Global Phytoplankton Distribution. To maximize optimal learning outcomes, it is suggested to complete the series in the following order:

  1. Global Phytoplankton Distribution Interactive Model
  2. Phytoplankton Distribution and Watersheds Interactive Model (current page)
  3. Chlorophyll Concentration and Incoming Shortwave Radiation Interactive Model
