North Atlantic Phytoplankton Bloom Triggered By Eddies
2012-07-06 05:16:57

redOrbit Staff & Wire Reports - Your Universe Online Scientists studying the annual growth of tiny plants in the North Atlantic Ocean have discovered that this year´s growth spurt began before the sun was able to offer the light needed to fuel the yearly phenomenon. The annual growth spurt of plankton, which is known as the North Atlantic Bloom, takes place each Spring, and results in an immense number of phytoplankton bursting into existence -- first "greening," then...

Some coral reef fish may be better prepared to cope with rising CO2 in the world´s oceans — thanks to their parents. Researchers at the ARC Centre of Excellence for Coral Reef Studies (CoECRS) today reported in the journal Nature Climate Change, encouraging new findings that some fish may be less vulnerable to high CO2 and an acidifying ocean than previously feared. “There has been a lot of concern around the world about recent findings that baby fish are highly...

The pico is a very small unit, even smaller than the nano as it is the equivalent of 10-12. The biologist Aitor Alonso has devoted himself to studying green algae of this imperceptible size existing in the Bilbao estuary, paying particular attention to the area beyond the Nervión estuary. This has enabled him to identify six genera and eleven nano- and picoplanktonic species that until now had not been catalogued in these waters. He has also put forward some measures designed to...

Acting through links between four trophic levels and across two ecosystems, purple loosestrife altered life in nearby ponds An elementary school science activity asks children who have each been assigned a wetland plant or animal to connect themselves with string and tape to other “organisms” their assigned plant or animal interacts with in some way. Once an ecosystem web has been created, the teacher describes an event that affects one “organism.” That...

[ Watch the Video ] redOrbit Staff & Wire Reports NASA officials announced on Thursday that an expedition they sponsored had uncovered a massive bloom of phytoplankton in the ice-capped waters of the Arctic Ocean -- a discovery which the U.S. space agency has called "as dramatic and unexpected as finding a rainforest in the middle of a desert." The findings, which came as part of Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment (ICESCAPE)...

Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution. However, it is less well known that evolutionary change in organisms also trigger fundamental changes in the environment. Yale University researchers found a prime example of this evolutionary feedback loop in a few lakes in Connecticut, where dams built 300 years ago in Colonial times trapped a fish called the alewife. In a study published May 23 in the journal...

Michael Crumbliss for RedOrbit.com This week new research was published that points to seagrasses as a solution to climate change. Seagrass can store up to twice the carbon of the world´s terrestrial forests. The paper, "Seagrass Ecosystems as a Globally Significant Carbon Stock," is the first global analysis of carbon stored in seagrasses and was published in the journal Nature Geoscience.  The research was led by James Fourqurean of Florida International University, 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...
