Description
Definition Waters dominated by Diatom Phytoplankton, single-cell algae that circulate passively or sink in the water column. This non-flagellated group possesses silica-based frustules that can form large and elaborate static appendages. They are considered desirable, high-quality food for grazers, supporting healthy food webs.
