Phytoplankton (/ ˌ f aɪ t oʊ ˈ p l æ ŋ k t ə n /) are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems.The name comes from the Greek words φυτόν (phyton), meaning 'plant', and πλαγκτός (planktos), meaning 'wanderer' or 'drifter'.
Some of the largest plankton are krill and feed the largest of animals, baleen whales. My first foray into the scientific world was a job sexing Jassa falcata (a tiny amphipod) under a microscope.
Chlorophyll α is the core photosynthetic pigment that all phytoplankton possess. Concentrations of this pigment, which can be measured remotely, is used as a proxy for phytoplankton biomass in a given location general, the more chlorophyll a, the more phytoplankton biomass, although the CHL a to C ratio May vary between species, and even within the species.

As plankton are rarely fished, it has been argued that mesoplankton abundance and species composition can be used to study marine ecosystems' response to climate change. This is because they have life cycles that generally last less than a year, meaning they respond to climate changes between years.
