Fish food fight: Fish don't eat trees after all, says new study
What constitutes fish food is a matter of debate. A high-profile study a few years ago suggested that fish get almost 50 percent of their carbon from trees and leaves, evidence for a very close link between the terrestrial and aquatic ecosystems. view more (2009-11-24)
New insight into predicting cholera epidemics in the Bengal Delta
Cholera, an acute diarrheal disease caused by the bacterium Vibrio cholerae, has reemerged as a global killer. Outbreaks typically occur once a year in Africa and Latin America. But in Bangladesh the epidemics occur twice a year - in the spring and again in the fall. view more (2009-11-05)

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)
Energetic bottleneck factors in catastrophic winter seabird losses
It's a terrible sight: hundreds of dead seabirds washed up on the seashore. These catastrophic events occur in the winter and are known as winter wrecks. view more (2009-07-17)
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)
Coral reefs found growing in cold, deep ocean

Common insecticide can decimate tadpole populations
The latest findings of a University of Pittsburgh-based project to determine the environmental impact of routine pesticide use suggests that malathion--the most popular insecticide in the United States--can decimate tadpole populations by altering their food chain, according to research published in the Oct. 1 edition of Ecological Applications. view more (2008-09-30)
Scientists reveal the lifestyle evolution of wild marine bacteria
Marine bacteria in the wild organize into professions or lifestyle groups that partition many resources rather than competing for them, so that microbes with one lifestyle, such as free-floating cells, flourish in proximity with closely related microbes that may spend life attached to zooplankton or algae. view more (2008-05-23)
Dartmouth researchers alarmed by levels of mercury and arsenic in Chinese freshwater ecosystem
A team of researchers, led by biologists at Dartmouth, has found potentially dangerous levels of mercury and arsenic in Lake Baiyangdian, the largest lake in the North China Plain and a source of both food and drinking water for the people who live around it. view more (2008-01-10)
Photo-monitoring whale sharks
Up to 20 meters long and weighing as much as 20 tons, its enormous size gives the whale shark (Rhincodon typus) its name. Known as the 'gentle giant' for its non-predatory behavior, this fish, with its broad, flattened head and minute teeth, eats tiny zooplankton, sieving them through a fine mesh of gill-rakers. view more (2007-12-26)
CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976] by mid-century if emissions are not dramatically... view more...

The sea-ice is getting thinner - A closer look at the climate and ecosystem of the Arctic Ocean
Large areas of the Arctic sea-ice are only one metre thick this year, equating to an approximate 50 percent thinning as compared to the year 2001. view more (2007-09-14)
Climatic variations influence the emergence of cholera in Africa
In studies aiming to understand better the emergence and persistence of cholera in Africa, IRD and CNRS researchers showed the strong correlation that exists between outbreaks and the different parameters linked to climate changes in West Africa. view more (2007-09-06)
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...

Northwest Atlantic Ocean ecosystems experiencing large climate-related changes
Ecosystems along the continental shelf waters of the Northwest Atlantic Ocean—from the Labrador Sea south of Greenland all the way to North Carolina—are experiencing large, rapid changes, report oceanographers funded by the National Science Foundation (NSF) in the Feb. 23, 2007, issue of the journal Science. view more (2007-02-26)
Risk of extinction accelerated due to interacting human threats
The simultaneous effect of habitat fragmentation, overexploitation, and climate warming could accelerate the decline of populations and substantially increase their risk of extinction, a study published in the Proceedings of the Royal Society B has warned. view more (2007-02-08)

New research in Chesapeake Bay, Pamlico Sound shows hurricanes, runoff tax water quality management efforts
A scientific study that involved analyzing phytoplankton in both North Carolina's Neuse River Estuary/Pamlico Sound and Maryland and Virginia's Chesapeake Bay offers a new lesson in light of recent increased hurricane activity along the East Coast, researchers say. view more (2005-12-23)
Advance in cholera bacteria points to new treatment and vaccine
Opening a new door to an effective vaccine and therapy for a disease that strikes thousands annually, researchers at Dartmouth Medical School discovered that the bacteria that causes the intestinal disease Cholera spreads in the environment in much the same way it infects humans. view more (2005-12-08)
