From
MERIS satellite data we can derive information on chlorophyll-a.
Chlorophyll-a is a chemical substance that is present in phytoplankton
("floating plants"). Observation of high concentrations of chlorophyll-a
in coastal waters mainly co-insides with high concentrations of
algae. Algae are organisms that mainly belong to this floating
plants group. The following websites show photographs of various
algae species and provide information on the remote sensing of
phytoplankton.

Algal blooms,
Red tide, Harmful Algal Blooms
Occasionally,
algae grow very fast or "bloom" and accumulate into dense, visible
patches near the surface of the water. "Red tide" refers to blooms
of certain phytoplankton species that contain reddish pigments;
they are usually not harmful. Harmful algal blooms (HAB's) contain
toxins or that cause negative impacts. Information on red tides
and harmful algae blooms can be found on the following sites:

Dinoflagellates,
Shellfish poisoning
Dinoflagellates
are single-celled organisms that have two distinctive flagella
(mini-ribbons) during at least part of their life cycle and/or
a special type of nucleus called a dinokaryon. They are probably
best known as a principal cause of "red tides" and they can also
cause paralytic shellfish poisoning.

Seaweeds
and algae
The
term seaweed refers to a certain group of large marine algae that
grow almost exclusively in shallow waters. The following sites
contain a lot of pictures of seaweeds:
