Mystery Solved: Marine Microbe Is Source of Rare Nutrient
A new study of microscopic marine microbes, called phytoplankton, by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of South Carolina has solved a ten-year-old mystery about the source of an essential nutrient in the ocean. view more (2009-09-30)
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)
Highest-ever winter water temperatures recorded
Tasmania's east coast is recording its highest-ever winter water temperatures of more than 13°C - up to 1.5°C above normal - due to a strengthening of an ocean current originating north of Australia. view more (2009-08-07)
NOAA bans commercial harvesting of krill
The National Oceanic and Atmospheric Administration (NOAA) today published a final rule in the Federal Register prohibiting the harvesting of krill in the Exclusive Economic Zone (EEZ) off the coasts of California, Oregon, and Washington. view more (2009-07-14)
Iron and biological production in the high-latitude North Atlantic
Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions. view more (2009-07-08)
Troubled waters: Low Apalachicola River flow may hurt gulf fisheries
Reductions in the flow of the Apalachicola River have far-reaching effects that could prove detrimental to grouper and other reef fish populations in the northeastern Gulf of Mexico, according to a new Florida State University study that may provide new ammunition for states engaged in a nearly two-decade water war. view more (2009-06-22)
Breakthrough made in assessing marine phytoplankton health
Researchers from Oregon State University, NASA and other organizations said today that they have succeeded for the first time in measuring the physiology of marine phytoplankton through satellite measurements of its fluorescence - an accomplishment that had been elusive for years. view more (2009-05-29)
NASA satellite detects red glow to map global ocean plant health
Researchers have conducted the first global analysis of the health and productivity of ocean plants, as revealed by a unique signal detected by a NASA satellite. view more (2009-05-29)
Timing is Everything for Northern Shrimp Populations in the North Atlantic
Even for Northern shrimp (Pandalus borealis), which support commercial fisheries worldwide, timing is everything in life. The tiny creatures, eaten in shrimp rolls and shrimp salad, occupy a pivotal role in the oceanic food chain and may serve as early indicators of changing climate due to their sensitivity to temperature. view more (2009-05-08)
Ocean Carbon: A Dent in the Iron Hypothesis
Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy's Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. view more (2009-05-07)
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)
A new view of oceanic phytoplankton
Phytoplankton comprise the forests of the sea, and are responsible for providing nearly half of the oxygen that sustains life on Earth including our own. However, unlike their counterparts on land, the marine plants are nearly exclusively microscopic in size, and mostly out of human sight. view more (2009-03-10)
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)
Saharan dust storms sustain life in Atlantic Ocean
Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. view more (2008-07-21)
Climate change causing significant shift in composition of coastal fish communities
A detailed analysis of data from nearly 50 years of weekly fish-trawl surveys in Narragansett Bay and adjacent Rhode Island Sound has revealed a long-term shift in species composition, which scientists attribute primarily to the effects of global warming. view more (2008-06-30)
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)
