Latest Biological oceanography Stories
A species of one of the world’s tiniest creatures, ocean plankton, is heading for extinction as it struggles to adapt to changes in sea temperature. And it may take local fisheries with it.
Danish and Australian biologists have developed a technique to determine if seagrass contain sulfur.
A new report looks at how extreme weather and an increase in non-point source pollution from agriculture and failing septic systems are spurring the spread of harmful algal blooms.
Until now, NASA satellites might have missed as much as 50 percent of the phytoplankton in the Southern Ocean. This would make it far more difficult to estimate the potential carbon capture of this vast area of the sea.
As the climate changes and oceans' acidity increases, tiny plankton seem set to succeed.

The X Prize Foundation has announced a $2-million competition to kick-start technology innovations to more accurately measuring the health of the oceans.
Rising water temperatures will have an adverse impact on plankton, serving as the catalyst for a series of events that will upset the balance of essential oceanic chemical cycles.
As meteorological science advances, we have all become used to long-term weather forecasts, such as predicting what the coming winter might bring. One group of scientists, however, has developed the first long-term forecast of conditions that matter for Pacific Northwest fisheries.
Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...
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...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
