About Plankton crash

• A plankton crash is when a dramatic bloom of plankton in a pond is replaced by very few viable plankton. This can be caused by a lack of nutrients or CO2
• Dead plankton can create large amounts of stable foam on the surface of the pond.
• A panel formed by the National Green Tribunal (NGT) investigated the red colouration of the sea in Puducherry and attributed it to a plankton crash.
• A specific species of phytoplankton, Noctiluca scintillans, was found to be ruptured, releasing red pigment into the sea.
• Environmental parameters such as sea surface temperature, salinity, pH, and dissolved oxygen were found conducive to the proliferation of this species.
