The Earth's oceans play a vital role in the carbon cycle, making it imperative that we understand marine biological activity enough to predict how our planet will react to the extra 25,000 million tons of carbon dioxide humans are pumping into the atmosphere annually.The color of oceanic seawater depends largely on the number of microscopic phytoplankton, marine plants that live in the well-lit surface layer. Just like land-based plants, phytoplankton accumulate carbon dioxide during...

Certain fish could disappear from restaurant menus and our plates at home by 2100, as global warming changes ocean food webs, a new study suggests. Climate change has the potential to threaten ecosystems all over the world, and those in the ocean are no exception. Two marine ecologists led a study of the effects of climate change on the food web of the Bering Sea, which currently provides about half of the fish caught in U.S. waters each year and nearly a third caught worldwide....

By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologistThe last fish you ate probably came from the Bering Sea. But during this century, the sea's rich food web"”stretching from Alaska to Russia"”could fray as algae adapt to greenhouse conditions."All the fish that ends up in McDonald's, fish sandwiches"”that's all Bering Sea fish," said USC marine ecologist Dave Hutchins, whose former...

MIAMI -- The sturdy steel trawler spent the summer on Fort Lauderdale's New River, but the sheltered waters haven't kept the company that owns it from an international storm of controversy over whether its owners' real aim is to help save the planet or just turn a profit. Planktos, a small California company, intends to spread as much as 100 tons of pulverized iron over the vast Pacific Ocean off the Galapagos Islands, hoping it will fertilize a rich crop of carbon dioxide-gobbling...

CORVALLIS, Ore. -- A new study suggests that the iron-rich winter runoff from Pacific Northwest streams and rivers, combined with the wide continental shelf, form a potent mechanism for fertilizing the nearshore Pacific Ocean, leading to robust phytoplankton production and fisheries. The study, by three Oregon State University oceanographers, was just published by the American Geophysical Union in its journal, Geophysical Research Letters. West coast scientists have observed that ocean...

An international team of scientists including Universit© Laval biologist Connie Lovejoy has discovered new life forms in the Arctic Ocean. The team's findings are reported in the January 12 edition of the journal Science. The researchers have discovered a new group of microscopic organisms, which they have baptized "picobiliphytes": pico because of their extremely small size, measured in millionths of a meter, bili because they contain biliproteins, highly fluorescent substances that...

Atmospheric scientists have reported a new and potentially important mechanism by which chemical emissions from ocean phytoplankton may influence the formation of clouds that reflect sunlight away from our planet. This intimate connection between life and the environment of Earth could have profound implications for the future of our planet's global ecosystem. Discovery of the new link between clouds and the biosphere grew out of efforts to explain increased cloud cover observed over an area...

MADRID -- Sweltering temperatures sweeping Europe have brought a plague of jellyfish to Spain's eastern seashores, forcing holidaymakers to stay out of the sea, the Red Cross said on Thursday. The unwelcome visitors, which can reach the size of a dinner plate, have flourished thanks to a glut of plankton brought on by higher sea temperatures and a decline in natural predators like dolphins and turtles. The Red Cross has treated more than 10,000 jellyfish stings this summer so far in the...

Transparent jellyfish-like creatures known as salps, considered by many a low member in the ocean food web, may be more important to the fate of the greenhouse gas carbon dioxide in the ocean than previously thought. In the May issue of Deep Sea Research, scientists report that salps, about the size of a human thumb, swarming by the billions in hot spots may be transporting tons of carbon per day from the ocean surface to the deep sea and keep it from re-entering the atmosphere. Salps are...

By Alister Doyle, Environment Correspondent OSLO (Reuters) - Scientists have found about 10-20 new species of tiny creatures in the depths of the Atlantic in a survey that will gauge whether global warming may harm life in the oceans, an international report said on Thursday. The survey, of tropical waters between the eastern United States and the mid-Atlantic ridge, used special nets to catch fragile zooplankton -- animals such as shrimp, jellyfish and swimming worms -- at lightless...

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...

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...
