Unique Experiment Uses Huge Plastic Containers To Study Ocean Acidification
2013-03-13 16:08:19

AlphaGalileo Foundation To study the effects of ocean acidification, ten huge plastic containers called mesocosms are placed in the Gullmar Fjord in Sweden. The project is unique: mesocosms of this size have never been used for such a long period of time. The experiment is part of a worldwide research project, and includes researchers from the University of Gothenburg, Sweden. This is the largest and longest experiment on the impact of climate change on marine ecosystems that have been...

Limited Phosphorus Makes Gulf Of Mexico Algae Even Meaner
2013-03-13 10:27:32

North Carolina State University When Gulf of Mexico algae don't get enough nutrients, they focus their remaining energy on becoming more and more poisonous to ensure their survival, according to a new study by scientists from North Carolina State University and the National Oceanic and Atmospheric Administration. The study shows that harmful and ubiquitous Karenia brevis algae, which cause red tide blooms across the Gulf of Mexico, become two to seven times more toxic when levels of...

Red Tide Killing Record Number Of Manatees In Florida
2013-03-11 10:44:02

Brett Smith for redOrbit.com - Your Universe Online A red algae bloom, also known as Red Tide, is currently killing a record number of manatees living off the coast of Florida. Last week, the Florida Fish and Wildlife Conservation Commission (FWC) found an average of 10 dead manatees a day and some observers said the phenomenon doesn´t appear to be receding. A toxin produced by the red algae affects the nervous system of the manatees causing them to drown. "This is probably...

How Sensitive US East Coast Regions May Be To Ocean Acidification Revealed By New Study
2013-03-01 12:17:31

Woods Hole Oceanographic Institution A continental-scale chemical survey in the waters of the eastern U.S. and Gulf of Mexico is helping researchers determine how distinct bodies of water will resist changes in acidity. The study, which measures varying levels of carbon dioxide (CO2) and other forms of carbon in the ocean, was conducted by scientists from 11 institutions across the U.S. and was published in the journal Limnology and Oceanography. “Before now, we haven't had a very...

Smartphone App Allows Seamen To Track Phytoplankton For Science
2013-02-24 08:08:54

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the Plymouth University Marine Institute have developed a new smartphone app that they claim will allow regular folks to help scientists track the impact of climate change on phytoplankton. In a statement released Friday, the university reports that scientists are concerned that the tiny organisms, which are at the bottom end of the marine life food chain, could be decreasing in numbers due to increasing sea...

Growth Of Toxic Algae Caused By Nitrogen From Pollution And Natural Sources
2013-02-07 10:17:49

San Francisco State University Nitrogen in ocean waters fuels the growth of two tiny but toxic phytoplankton species that are harmful to marine life and human health, warns a new study published in the Journal of Phycology. Researchers from San Francisco State University found that nitrogen entering the ocean -- whether through natural processes or pollution -- boosts the growth and toxicity of a group of phytoplankton that can cause the human illness Amnesic Shellfish Poisoning....

Ancient And Modern Tiny Marine Algae Provide Climate Change Clues
2013-02-04 10:21:39

National Oceanography Centre, Southampton (UK) Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow. Coccolithophores, a type of plankton, are not only widespread in the modern ocean but they are also prolific in the fossil record because their tiny calcium carbonate shells are...

Scientists Analyze Costs And Benefits Of Rock Dissolving Practices
2013-01-22 12:14:08

Brett Smith for redOrbit.com - Your Universe Online Geoengineering is a controversial and illegal practice that attempts to mitigate the forces of climate change on a grand scale. Many see this attempt to alter global climate via artificial means as a ℠quick fix´ with potential long-term negative effects. However, despite the contentious nature of geoengineering, scientists from the Alfred Wegener Institute in Bremerhaven, Germany decided to analyze a ℠rock...

Bondi Beach Closed Due To Algae Bloom
2012-11-27 19:59:28

Lee Rannals for redOrbit.com — Your Universe Online Tourists at Australia's Bondi Beach were surprised to see what looked like blood-soaked water heading their way this week. Bondi Beach is a popular tourists destination around Sydney Australia, but the area had to be closed after a huge algal bloom took over some of the area's waters. Ten News Sydney reported that despite the warnings, a number of beachgoers were still venturing into the water and swimming through the red...

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...
