Coscinodiscus are a genus of diatoms. Diatoms are unicellular, photosynthetic phytoplankton whose bodies are made up of silica, or glass. Many diatom bodies manifest in simple geometric shapes, and Coscinodiscus is no different with a body shaped like a squat cylindrical drum.

Where are Coscinodiscus found?

Coscinodiscus range of existence from the warm tropic waters up until the cold Arctic ecotone waters, they can’t tolerate colder waters. They are widespread and area good indicator of rising warming waters. Their distribution could allows us to tract global warming through the digital imaging of their chlorophyll.

How does Coscinodiscus survive?

Coscinodiscus do not have adaptations that help keep them afloat. They rely on the stratification of the water column to keep them at the surface: they grow in the warm water layer, at the top of the thermocline. This water can be moved about by wind and tide, but cannot easily mix with the cool, dark water below.

What affects plankton population?

Phytoplankton growth depends on the availability of carbon dioxide, sunlight, and nutrients.

What is Phytoplanktons habitat?

Description: Phytoplankton are microscopic plants that live in the ocean. … Habitat: Because phytoplankton photosynthesises they must therefore live in the well-lit surface layer (termed the euphotic zone) of an ocean, sea, lake, or other body of water.

Why is plankton important?

Plankton are the unseen heroes of many ecosystems providing food to a wide variety of species from tiny bivalves to whales. Though they are microscopic in size, organisms called plankton play a big role in marine ecosystems. They provide the base for the entire marine food web.
