Latest Biological oceanography Stories
Tiny marine organisms called zooplankton can use specialized adaptations that allow them to hide from predators in areas of the ocean where oxygen levels are so low that almost nothing can survive, but they may run into trouble as these areas expand due to climate change.
Scientists said a surprising appearance of plankton and whales through the Northwest Passage might be a sign of how global warming is affecting animals and plants in the oceans as well as on land.
The world's oceans support vast populations of single-celled organisms (phytoplankton) that are responsible, through photosynthesis, for removing about half of the carbon dioxide that is produced by burning fossil fuels â€“ as much as the rainforests and all other terrestrial systems combined.
Scientists embark this week from Alaska on the second and final campaign of a NASA field campaign to study how changing conditions in the Arctic affect the ocean's chemistry and ecosystems.
The world's oceans are declining much faster than previously believed, a consortium of ocean experts warned on Monday.
A new Baylor University study has found that sunlight decreases the toxicity of golden algae, which kills millions of fish in the southern United States every year.
ESAâ€™s new Aquaculture project will support sustainable aquaculture by developing an information service based on state-of-the-art remote sensing.
A new study by researchers at the Virginia Institute of Marine Science (VIMS) shows that jellyfish are more than a nuisance to bathers and boaters, drastically altering marine food webs by shunting food energy from fish toward bacteria.
Scientists discover how "Didymo" algae bloom in pristine waters with few nutrients.
Since the Industrial Revolution, over half of all the CO2 produced by burning fossil fuels has been absorbed by the ocean, making pH drop faster than any time in the last 650,000 years and resulting in ocean acidification.
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...
