Latest Biological oceanography Stories
University of Plymouth A study into marine life around an underwater volcanic vent in the Mediterranean, might hold the key to understanding how some species will be able to survive in increasingly acidic sea water should anthropogenic climate change continue. Researchers have discovered that some species of polychaete worms are able to modify their metabolic rates to better cope with and thrive in waters high in carbon dioxide (CO2), which is otherwise poisonous to other, often...
The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed -- with implications for future climate prediction.
An international group of scientists has created a global atlas of oceanic plankton -- from bacteria to krill -- by recording times, places and concentrations of plankton occurrences.
University of Adelaide marine biologists have found that reducing nutrient pollution in coastal marine environments should help protect kelp forests from the damaging effects of rising CO2.
An ancient bloom of life that occurred just after the last ice age isn’t what it seemed at first, according to new research in the journal Nature Geoscience.
A new study says that the motility of phytoplankton allows the tiny ocean plants to determine their fate in ocean turbulence by forming 'social mixers.'
While many studies have focused on how ocean acidification may impact various individual species, an international team of researchers has just published a study on how an entire ecosystem can be affected by a more acidic ocean.
It may be called the Yellow Sea, but the northern part of the East China Sea has turned green due to the largest algal bloom in the history of the Asian nation, various media outlets are reporting.
A new study on the feeding habits of ocean microbes calls into question the potential use of algal blooms to trap carbon dioxide and offset rising global levels.
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...
