Saharan sand carries nitrogen, phosphorus and iron — delicious and essential treats for phytoplankton, which are
microscopic ocean plants.

Ajit Subramaniam is a Columbia University professor who tracks
microscopic plant life in the
ocean.
The shrimp represent centimeter - sized swimmers, including krill and shrimplike copepods, found throughout the world's
oceans that may together be capable of mixing
ocean layers — and delivering nutrient - rich deep waters to phytoplankton, or
microscopic marine
plants, near the surface, the researchers suggest.
A long - standing puzzle in
ocean photosynthesis was why phytoplankton failed to grow fast in parts of the Pacific Ocean; after all, the microscopic plants have access to plenty of carbon dioxide thanks to upwelling w

microscopic plants called diatoms that settle to the seafloor after dying, but this core contained none.
For example, a lack of iron limits the growth of
microscopic plants in the Southern
Ocean around Antarctica and elsewhere, a fact that prompted marine biologist John Martin to famously muse: «Give me half a tanker of iron, and I'll give you the next ice age.»
In many parts of the
ocean the productivity of phytoplankton —
microscopic plants at the base of the marine food chain — is limited by the availability of dissolved iron.
It concentrates on the
ocean's
microscopic phytoplankton, describing how these tiny green
plants supply half the planet's oxygen and form an essential part of the sea's food chains.
These giants of the
ocean swim with open mouth to absorb the nutritious soup made up from
microscopic water
plants, plankton, egg fish and even tiny fish.
The rate of accumulation depends on how much CO2 mankind emits and how much of this excess CO2 is absorbed by
plants and soil or is transported down into the
ocean depths by plankton (
microscopic plants and animals).
Then, by analysing the sediments for chemical fossils made by certain
microscopic plants that live in sea ice and the surrounding
oceans, Knies and his co-workers were able to fingerprint the environmental conditions as they changed through time.
The first place that carbon moves from the atmosphere into the
ocean is at its sun - warmed surface, where
microscopic floating
plants called phytoplankton consume carbon dioxide for energy (just like grass and trees).
