Rising Temperatures Could Upset Natural Ocean Cycles
2013-09-09 04:15:09

redOrbit Staff & Wire Reports - Your Universe Online Rising water temperatures will have an adverse impact on plankton, serving as the catalyst for a series of events that will upset the balance of essential oceanic chemical cycles, according to new research published in Sunday’s edition of the journal Nature Climate Change. Scientists from the University of East Anglia (UEA) in the UK examined the impact that ocean temperatures can have on the plankton ecosystems found in the...

Predicting Fish Habitats Months In Advance With New Ocean Forecast
2013-08-31 07:53:32

April Flowers for redOrbit.com - Your Universe Online As meteorological science advances, we have all become used to long-term weather forecasts, such as predicting what the coming winter might bring. A new study from the University of Washington and federal scientists, however, has developed the first long-term forecast of conditions that matter for Pacific Northwest fisheries. “Being able to predict future phytoplankton blooms, ocean temperatures and low-oxygen events could help...

Understanding Marine Life's Ability To Adapt To Climate Change
2013-08-26 06:03:13

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...

New Variability In Iron Supply To The Oceans With Climate Implications Discovered By Scientists
2013-07-19 09:44:51

National Oceanography Centre, Southampton (UK) 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. Iron is key to the removal of carbon dioxide from the Earth's atmosphere as it promotes the growth of microscopic marine plants (phytoplankton), which mop up the greenhouse gas and lock it away in the ocean. A new study, led by researchers based at the...

Scientists Create Global Atlas On Oceanic Plankton
2013-07-19 10:05:40

April Flowers for redOrbit.com - Your Universe Online An international group of scientists has created a global atlas of oceanic plankton -- from bacteria to krill -- by recording times, places and concentrations of the organism's occurrences. Over 70 percent of the world's surface is covered by the oceans. Compared with terrestrial ecosystems, the animals and plant species of the oceans have been researched relatively little. Because of this, the knowledge base concerning the...

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. The researchers have found a combined effect on kelp forests from nutrient pollution and higher CO2, which could have a devastating impact on Australia's marine ecosystems. "When we manipulated CO2 and nutrient levels in an experimental marine ecosystem we found the effect of both of them together...

Ancient Algal Bloom Mystery Solved
2013-07-15 15:05:24

Brett Smith for redOrbit.com - Your Universe Online 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. Scientists had long believed that the bloom, which occurred around 14,000 years ago, was spurred by rising sea levels washing iron into the ocean. However, the new study suggested that a "perfect storm" of conditions allowed for the bloom to happen, and not simply the abundance of...

Phytoplankton Ocean Turbulence Social Mixers
2013-07-15 12:58:35

[Watch the video: Phytoplankton Social Mixers] Lee Rannals for redOrbit.com - Your Universe Online The motility of phytoplankton allows the tiny ocean plants to determine their fate in ocean turbulence, according to scientists at MIT and Oxford University. Researchers wrote in the journal Nature Communications that the individual vortices that make up ocean turbulence are like social mixers for phytoplankton. This social mixer brings similar cells into close proximity, helping to...

Ocean Acidification Has Transformed Delicate Ecosystem
2013-07-09 15:43:58

Brett Smith for redOrbit.com - Your Universe Online 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. As one of the consequences of climate change, ocean acidification is expected to significantly increase if carbon emissions continue at current rates. According to the study, which was published in...

Sea Lettuce Invades Chinese Beach
2013-07-06 05:51:46

redOrbit Staff & Wire Reports - Your Universe Online 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. According to AFP news agency reports, the State Oceanic Administration is reporting that the algae, which is known as Enteromorpha prolifera, started appearing about one week ago, and among the places affected are a public beach 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 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...
