The measurement and distribution of living microscopic plant matter, commonly referred to as phytoplankton or algae, has been of interest to scientists, researchers, and aquatic resource managers for decades. An understanding of phytoplankton populations and their distribution enables researchers to draw conclusions about an aquatic system's health, composition, and ecological status. 

Phytoplankton populations are typically estimated by measuring chlorophyll a, the primary photosynthetic pigment present in all forms of algae. Currently, chlorophyll can be estimated in lakes, rivers, reservoirs, and coastal and open ocean waters across the globe.
