Latest Biological oceanography Stories
Researchers at the Plymouth University Marine Institute have developed a new smartphone app that they claim will allow regular folks to help scientists track the impact of climate change on phytoplankton.
Nitrogen in ocean waters fuels the growth of two tiny but toxic phytoplankton species that are harmful to marine life and human health, warns a new study published in the Journal of Phycology.
Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago.
Geoengineering is a controversial and illegal practice that attempts to mitigate the forces of climate change on a grand scale. Many see this attempt to alter global climate via artificial means as a ‘quick fix’ with potential long-term negative effects.
Tourists at Australia's Bondi Beach were surprised to see what looked like blood-soaked water heading their way this week.
An international team of researchers has uncovered the first evidence that marine creatures living in the Antarctic region are being affected by ocean acidification.
New research shows that ocean turbulence directly affects the ability of microscopic marine organisms to recycle organic material back into the food web.
Phytoplankton are important for the sustainability of the aquatic food web. However, future warming oceans could significantly alter the populations of these important organisms.
In a new study, researchers examined the poop of small forage fish in order to gain an understanding of its role in the ocean's carbon removal process.
Scientists at the University of Rhode Island's Graduate School of Oceanography have made the first observation of a predator avoidance behavior by a species of phytoplankton, a microscopic marine plant.
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...
