Israeli, U.S., German Researchers Use Acoustic 3-D Imaging System To Unveil Remarkable Behavior Of Ocean Plankton
An international team of scientists from Israel, the United States and Germany, led by Prof. Amatzia Genin of the Hebrew University of Jerusalem and the Interuniversity Institute for Marine Sciences in Eilat, has provided, for the first time, evidence of the remarkable dynamics responsible for the formation of large aggregations of microscopic... view more...

Diversity in the deep blue seas
Nature magazine has published an article by Xabier Irigoien, a researcher at AZTI, the Basque Fisheries and Marine Technological Research Centre. The article provides data on the diversity of marine life at the bottom of the sea - particularly amongst algae. Species diversity Most research carried out on the diversity of species has been with land... view more... (2004-06-28)
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)
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)
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)
Does climate change affect marine productivity?
The scientific magazine NATURE, a worldwide leader, has published an article of a research worker of the Basque foundation AZTI, Xabier Irigoien, about marine ecosystem. The prestigious scientific magazine NATURE has published in its last issue of September an article and cover, whose first author is the research worker of the Basque foundation... view more...

Beautiful diatoms: pattern for stable construction
AWI publication in 'Nature' Scientists from the Alfred Wegener Institute (AWI) published new results concerning the structure and material properties of diatoms in the science journal "Nature" on 20th february 2003 (Nature 421: 841-843). These single-celled marine algae are responsible for the majority of oxygen and biomass production in the... view more... (2003-02-21)
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)
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)
Iron Fertilisation Of The Ocean Raises The Food Supply Of Marine Animals And Transports Carbon Dioxide To The Deep Ocean
An international team of scientists that recently carried out an experiment in the South Atlantic on board RV „Polarstern" of the Alfred Wegener Institute for Polar and Marine Research has found that an algal bloom induced by iron fertilisation transported carbon dioxide to the deep ocean. The bloom also stimulated growth of zooplankton... view more... (2004-04-05)
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)
Scientists discover global pattern of big fish diversity in open oceans
A new study released in Science (via Science Express) on July 28th reveals a striking downward trend in the diversity of fish in the open ocean - the largest and least known part of our planet. view more (2005-07-29)
FLUCTUATIONS IN BIOLOGICAL PRODUCTION IN THE EQUATORIAL PACIFIC UNDERTHE EFFECT OF EL NINO
A region of the western equatorial Pacific, the Pacific warm pool, has exceptionally warm surface waters (an average 28.5°C) which have low salinity and are oligotrophic (nutrient-poor). At the Equator the Eastern edge of this pool comes into contact with cooler water (24°C on average) which is saline and nutrient rich (especially in... view more... (1999-05-11)
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)
Towards improved management of reservoirs in the semi-arid Northeast region of Brazil
In the Northeast region of Brazil, reservoirs called a'§udes are the main water resource during periods of drought, which are frequent and consequently often catastrophic in this part of Brazil. IRD has since 1995 been conducting a research programme on these reservoirs, in conjunction with the Federal Rural University of Pernambuco's Department... view more... (2000-05-17)
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)

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)
Radioactive plutonium remains from US military accident in Spain
Researchers from the Physics Department and the Institute of Environmental Science and Technology (ICTA) of the Universitat Autònoma de Barcelona have detected concentrations of radioactive plutonium and americium in plankton from the coast of Palomares (south-east coast of Spain), with an activity level five times higher than the average... view more...
