Latest Planktology Stories
A new article published in the 29 July issue of the international journal Nature reveals for the first time that microscopic marine algae known as "phytoplankton" have been declining globally over the 20th century.
During NASA's ICESCAPE voyage to the Arctic, scientists have been looking at the phytoplankton in the Arctic's Chukchi Sea -- how many, how big and at what depths they are found, but there are other ways of looking at these small life forms.
A team of scientists has returned to the North Atlantic to gather more data on the Icelandic volcanic eruption that took place earlier this year.
New research indicates that the interactions of microscopic organisms around a particular organic material may alter the chemical properties of the ocean and ultimately influence global climate by affecting cloud formation in the atmosphere.
ICESCAPE, NASA's first oceanographic field campaign, is studying the physics, chemistry and biology of the ocean and ice within a changing Arctic.
Adding nutrients to the sea could decrease viral infection rates among phytoplankton and enhance the efficiency of the biological pump, a means by which carbon is transferred from the atmosphere to the deep ocean.
Lack of sufficient iron may be a significant factor in controlling massive blooms of Emiliania huxleyi, a globally important species of marine algae or phytoplankton.
Even in the dark abyss of the deep ocean animal communities can undergo rapid, widespread and radical changes.
Algae obtain nitrate from deep waters 250 meters beneath the surface.
Computer simulations performed by researchers at the National Oceanography Centre and the University of Glasgow show how oceanic stirring and mixing influence the formation and dynamics of plankton patches in the upper ocean.
A salp is a barrel-shaped, free-floating tunicate (any living organism which has a saclike body enclosed in a thick membrane or tunic with two openings or siphons for the ingress and egress of water). It moves by contracting which pumps water through its body. The salp strains the water with internal feeding filters as it goes through the body. It consumes phytoplankton that are strained from the water. Salps are common throughout equatorial, temperate, and colder seas. They are most often...
The South American pilchard, Sardinops sagax, is a sardine of the Family Clupeidae, the only member of the genus Sardinops, found in the indo-Pacific oceans. Their length is up to 15.75 in (40 cm). It has a number of other common names: Australian pilchard, Blue pilchard, Blue-bait, Californian pilchard, Chilean sardine, Japanese pilchard, Pacific sardine, and Southern African pilchard. The South American pilchard is a coastal species that forms large schools. Coloration is blue green on...
