Nitrogen fixation and phytoplankton blooms in the southwest Indian Ocean
Observations made by Southampton scientists help understand the massive blooms of microscopic marine algae - phytoplankton - in the seas around Madagascar and its effect on the biogeochemistry of the southwest Indian Ocean. view more (2009-08-17)
Arctic climate under greenhouse conditions in the Late Cretaceous
New evidence for ice-free summers with intermittent winter sea ice in the Arctic Ocean during the Late Cretaceous - a period of greenhouse conditions - gives a glimpse of how the Arctic is likely to respond to future global warming. view more (2009-07-09)
Climate change threatens Lake Baikal's unique biota
Siberia's Lake Baikal, the world's largest and most biologically diverse lake, faces the prospect of severe ecological disruption as a result of climate change, according to an analysis by a joint US-Russian team in the May issue of BioScience. view more (2009-05-01)
Ancient diatoms lead to new technology for solar energy
Engineers at Oregon State University have discovered a way to use an ancient life form to create one of the newest technologies for solar energy, in systems that may be surprisingly simple to build compared to existing silicon-based solar cells. view more (2009-04-09)
Mighty diatoms: Global climate feedback from microscopic algae
Tiny creatures at the bottom of the food chain called diatoms suck up nearly a quarter of the atmosphere's carbon dioxide, yet research by Michigan State University scientists suggests they could become less able to "sequester" that greenhouse gas as the climate warms. The microscopic algae are a major component of plankton living in... view more... (2009-03-18)
Climate-related changes on the Antarctic peninsula
Scientists have long established that the Antarctic Peninsula is one of the most rapidly warming spots on Earth. view more (2009-03-17)
Decline of carbon dioxide-gobbling plankton coincided with ancient global cooling
The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. view more (2009-01-09)
Algal biomonitor
A paper published in the current issue of the International Journal of Environment and Pollution, explains how a DNA test can be used to detect harmful algal blooms across the globe. view more (2008-10-01)
Complex ocean behavior studied with 'artificial upwelling'
A team of scientists is studying the complex ocean upwelling process by mimicking nature - pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production. view more (2008-09-03)
Antarctic Fossils Paint a Picture of a Much Warmer Continent
National Science Foundation-funded scientists working in an ice-free region of Antarctica have discovered the last traces of tundra--in the form of fossilized plants and insects--on the interior of the southernmost continent before temperatures began a relentless drop millions of years ago. view more (2008-08-06)
Microbial stowaways: Are ships spreading disease?
Ships are inadvertently carrying trillions of stowaways in the water held in their ballast tanks. When the water is pumped out, invasive species could be released into new environments. Disease-causing microbes could also be released, posing a risk to public health, according to an article in the May issue of Microbiology Today. view more (2008-05-29)

Diatoms discovered to remove phosphorus from oceans
Scientists at the Georgia Institute of Technology have discovered a new way that phosphorus is naturally removed from the oceans -- its stored in diatoms. The discovery opens up a new realm of research into an element that's used for reproduction, energy storage and structural materials in every organism. The research appears in the May 2, 2008,... view more... (2008-05-05)
Ecologists, material scientists pursue genetics of diatom's elegant, etched casing
Diatoms - some of which are so tiny that 30 can fit across the width of a human hair - are so numerous that they are among the key organisms taking the greenhouse gas carbon dioxide out of the Earth's atmosphere. view more (2008-01-24)
In diatom, scientists find genes that may level engineering hurdle
Denizens of oceans, lakes and even wet soil, diatoms are unicellular algae that encase themselves in intricately patterned, glass-like shells. Curiously, these tiny phytoplankton could be harboring the next big breakthrough in computer chips. view more (2008-01-22)
Greenhouse ocean may downsize fish
By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist. view more (2008-01-14)
Nature leads the way for the next generation of paints, cosmetics and holograms
A plant-like micro-organism mostly found in oceans could make the manufacture of products, from iridescent cosmetics, paints and fabrics to credit card holograms, cheaper and 'greener'. view more (2007-10-04)
North America's northernmost lake affected by global warming
Analyses conducted by researchers from Universite Laval's Center for Northern Studies reveal that the continent's northernmost lake is affected by climate change. view more (2007-09-27)
Waters off Washington state only second place in world where glass sponge reefs found
Thirty miles west of Grays Harbor, University of Washington scientists have discovered large colonies of glass sponges thriving on the seafloor. The species of glass sponges capable of building reefs were thought extinct for 100 million years until they were found in recent years in the protected waters of Canada's Georgia and Hecata straits, the... view more...
