Meaning and Definition

The community of planktonic organisms that inhabit the middle depths of a body of water, typically below the surface layer but above the deep sea floor.

Plankton that live at intermediate depths, often defined by a specific depth range (e.g., 200–1000 meters) or light level, distinct from surface-dwelling (epiplankton) and deep-sea (bathypelagic) plankton. It refers to the organisms themselves as a collective ecological group.

Dialectal Variation

British vs American Usage

Differences

No spelling or core definition differences. Usage is identical in both varieties, confined to technical/scientific contexts.

Connotations

None beyond its strict scientific meaning.

Frequency

Extremely rare in general discourse. Used with identical frequency and context in UK and US academic/technical writing.

Common Mistakes When Using “mesoplankton”

  • Misspelling as 'mesoplanton' or 'mezoplankton'.
  • Confusing it with 'microplankton' (defined by size) or 'meroplankton' (temporary plankton).
  • Using it in non-scientific contexts where 'plankton' alone is sufficient.

FAQ

Frequently Asked Questions

No. Zooplankton refers to animal plankton. Mesoplankton is defined by depth. Mesoplankton can include zooplankton, but also other organisms like certain protists.

It is a technical term used almost exclusively in marine biology, oceanography, and related environmental sciences.

Phytoplankton are photosynthetic (plant-like) plankton, usually found in sunlit surface waters. Mesoplankton are defined by depth (middle waters) and can include both animals (zooplankton) and non-photosynthetic organisms.

Mesoplankton play a crucial role in the 'biological pump', transporting carbon from the surface to deeper ocean layers through their feeding and migration, thus impacting global carbon cycles.

The community of planktonic organisms that inhabit the middle depths of a body of water, typically below the surface layer but above the deep sea floor.

Mesoplankton is usually technical, scientific (marine biology, oceanography, ecology) in register.

Learning

Memory Aids

Mnemonic

Think: MESO = middle (like Mesopotamia, the land between two rivers). MESOPLANKTON = the plankton that live in the MIDDLE of the water column.

Conceptual Metaphor

THE OCEAN IS A LAYERED CAKE / VERTICAL CITY. Mesoplankton are the residents of the middle floors, between the bustling surface and the dark basement.
