Climate Change Slowing Down Deep Ocean Conveyor Belt
2014-03-24 08:42:04

Katherine Unger Baillie, University of Pennsylvania Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe. A new study by the University of Pennsylvania’s Irina Marinov and Raffaele Bernardello and colleagues from McGill University has found that recent climate change may be acting to slow down one of these conveyer belts, with potentially serious consequences for the future of the planet’s climate....

emission and transport of dust and other important aerosols to the Southern Ocean on Dec. 30, 2006

April Flowers for redOrbit.com - Your Universe Online In a region of the Southern Ocean, iron fertilization caused plankton to thrive during the last ice age, according to a new study from Princeton University and the Swiss Federal Institute of Technology in Zurich. The findings, published in Science, confirm a longstanding theory that wind-borne dust carried iron to this region of the Antarctic. This iron dust drove plankton growth and eventually led to the removal of carbon dioxide...

Plankton Make Scents For A Cooler Planet And Seabirds
2014-03-21 08:22:49

University of California, Davis The top predators of the Southern Ocean, far-ranging seabirds, are tied both to the health of the ocean ecosystem and to global climate regulation through a mutual relationship with phytoplankton, according to newly published work from the University of California, Davis. When phytoplankton are eaten by grazing crustaceans called krill, they release a chemical signal that calls in krill-eating birds. At the same time, this chemical signal — dimethyl...

Ocean Food Web Plays Key Role In The Global Carbon Cycle
2014-03-12 10:39:50

University of California - Santa Barbara Nothing dies of old age in the ocean. Everything gets eaten and all that remains of anything is waste. But that waste is pure gold to oceanographer David Siegel, director of the Earth Research Institute at UC Santa Barbara. In a study of the ocean's role in the global carbon cycle, Siegel and his colleagues used those nuggets to their advantage. They incorporated the lifecycle of phytoplankton and zooplankton — small, often microscopic animals...

Toxic Algae Most Likely Cause Of Ancient Chilean Whale Strandings
2014-02-26 10:08:48

Brett Smith for redOrbit.com - Your Universe Online A site in the Atacama Desert of Northern Chile has become well known for its wealth of ancient marine mammal fossils, deposited there by a series of mass strandings. While the cause of whale or other mammal strandings that take place today can often be identified, the cause behind ancient strandings is much more difficult to pin down. According to a newly published report in the Proceedings of the Royal Society B, an international...

Secret World Of The Plastisphere Being Uncovered
2014-02-26 09:01:39

American Geophysical Union Scientists are revealing how microbes living on floating pieces of plastic marine debris affect the ocean ecosystem, and the potential harm they pose to invertebrates, humans and other animals. New research being presented here today delves deeper into the largely unexplored world of the “Plastisphere” – an ecological community of microbial organisms living on ocean plastic that was first discovered last year. When scientists initially studied the...

Hannah Hickey, University of Washington The phrase, 'Eat your vitamins,' applies to marine animals just like humans. Many vitamins, including B-12, are elusive in the ocean environment. University of Washington researchers used new tools to measure and track B-12 vitamins in the ocean. Once believed to be manufactured only by marine bacteria, the new results show that a whole different class of organism, archaea, can supply this essential vitamin. The results were presented Feb. 24 at...

Fluctuation 'adds insult to injury' for marine creatures A new Duke University-led study has documented dramatic, natural short-term increases in the acidity of a North Carolina estuary. "The natural short-term variability in acidity we observed over the course of one year exceeds 100-year global predictions for the ocean as a whole and may already be exerting added pressure on some of the estuary's organisms, particularly shelled organisms that are especially susceptible to changes in...

Ocean Acidification
2013-04-01 10:32:20

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...

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...
