Discovery could lead to new methods for environmental remediation and speeding up chemical reactions A glow coming from the glassy shell of microscopic marine algae called diatoms could someday help us detect chemicals and other substances in water samples. And the fact that this diatom can glow in response to an external substance could also help researchers develop a variety of new, diatom-inspired nanomaterials that could solve problems in sensing, catalysis and environmental...

Zooplankton Among First To Show Evidence Of Exposure To Deepwater Horizon Oil
2012-03-23 05:24:35

Ryan Parson for Redorbit.com Oil remnants from the Maconda-1 oil field have been discovered in animals in the northern Gulf of Mexico. Zooplankton samples collected from the Gulf of Mexico have shown positive evidence of exposure to oil that may have directly originated from the Deepwater Horizon oil spill. The effects of the deadly British Petroleum R/V Deepwater Horizon oilrig explosion that took place on April 20, 2010, will more than likely be present for many years to come....

Phytoplankton Key to a Healthy Planet says Canada Research Chair at the Forefront of Phytoplankton Research Maria (Maite) Maldonado, Canada Research Chair in Phytoplankton Trace Metal Physiology at The University of British Columbia, has made understanding the intricacies of marine phytoplankton her life's work. These tiny, single-celled algae, which act as a natural sponge for carbon dioxide and are a critical part of the global carbon cycle, may play a key role in ensuring the health of...

Pacific Carbon Pump Speeds Up In Summer

An international team of scientists led by University of Hawaiʻi at Mānoa oceanographer David Karl has documented a regular, significant and unexpected increase in the amount of particulate matter exported to the deep sea in the North Pacific Subtropical Gyre. They suspect the previously undocumented phenomenon may be a response to day length, a general phenomenon known as photoperiodism. Measuring the biological carbon pump Using 13 years of...

Scientists Have Questions Concerning Jellyfish Blooms
2012-02-02 06:01:43

Scientists are questioning whether jellyfish blooms are real or just perceived by media hype. The report, which appears in the journal BioScience, questions the validity of increased jellyfish populations being reported around the world. The report was issued by the Global Jellyfish Group, which is a consortium of around 30 experts on gelatinous organisms, climatology, oceanography, and socioeconomics from around the globe. Rob Condon, who led the study, says “Clearly, there are...

Ultraviolet radiation is the catalyst for cellular damage in phytoplankton The Bren School-based authors of a study published Jan. 20 in the journal PLoS ONE have observed toxicity to marine organisms resulting from exposure to a nanoparticle that had not previously been shown to be toxic under similar conditions. Lead author and assistant research biologist Robert Miller and co-authors Arturo Keller and Hunter Lenihan — both Bren School professors and lead scientists at the UC...

New process for producing biodiesel from microalgae oil The available amount of fossil fuels is limited and their combustion in vehicle motors increases atmospheric carbon dioxide levels. The generation of fuels from biomass as an alternative is on the rise. In the journal Angewandte Chemie, Johannes A. Lercher and his team at the Technische Universitaet Muenchen have now introduced a new catalytic process that allows the effective conversion of biopetroleum from microalgae into diesel...

In 1997, scientists at the Center for Neurodynamics at the University of Missouri - St. Louis demonstrated that special sensors covering the elongated snout of paddlefish are electroreceptors that help the fish detect prey by responding to the weak voltage gradients that swimming zooplankton create in the surrounding water. Now some of the same researchers have found that the electroreceptors contain oscillators, which generate rhythmical firing of electrosensory neurons. The oscillators...

Image 1 - Run-off, Emissions Deliver Double Whammy To Coastal Marine Creatures
2011-10-25 03:07:28

Increasing acidification in coastal waters could compromise the ability of oysters and other marine creatures to form and keep their shells, according to a new study led by University of Georgia researchers. Their findings will be published in the November 2011 issue of Nature Geoscience. The researchers determined the combined effects of fertilizer runoff carried by the Mississippi River to the northern Gulf of Mexico and excess atmospheric carbon dioxide from burning fossil fuels result...

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...
