algae sampling News

Louisiana State University, USA, researchers Sibel Bargu and Ana Garcia (Department of Oceanography and Coastal Sciences) have discovered toxic algae in vast, remote regions of the open ocean for the first time. The recent findings are published in the Proceedings of the National Academy of Sciences (PNAS). Harmful algal blooms (HABs) are reported as increasing both geographically and in ...

This achievement represents a significant milestone in NOAA's effort to monitor the type and toxicity of harmful algal blooms (HABs). HABs are considered to be increasing not only in their global distribution, but also in the frequency, duration, and severity of their effects. HABs damage coastal ecosystem health and pose threats to humans as well as marine life. Climate change is expected to ...

Global warming due to the excessive use of fossil fuels is becoming a problem which has prompted and accelerated the search for alternative fuels. Among the more attractive alternatives is biomass fuel, which is attracting considerable attention. Microalgae can be used for the production of oil without competing with food production, and to a greater extent than other biofuels, its productivity ...

Blue-green algae blooms that can turn toxic in freshwater lakes and can kill bathers, farm animals and domestic pets that drink the water are becoming more widespread across the world, according to new research. A combination of excess use of fertilizers containing phosphorus and nitrogen, untreated sewage releases, and warmer water caused by climate change is leading to an increasing threat of ...

Algae-based biofuels such as biodiesel or bioethanol, have significant advantages over crop-based biofuels. Algae grow at a significantly faster rate than more complex plants, they have far greater yield per unit area and they can be grown in compact, closed systems. One further advantage is the short lifespan and hence a faster cycle of testing and research into suitable biofuel candidates. It ...

On Wednesday, April 13, 2011, the American Water Works Association (AWWA) will host the Algae Source to Treatment: Sampling Methods, Online Monitoring, and Cyanobacteria webcast. Part one of a two-part series, the webcast will review the most common and problematic algae in surface water supplies, including cyanobacteria or blue-green algae. The webcast will focus on identifying sampling and ...

A vast bloom of toxic algae off the West Coast is denser, more widespread and deeper than scientists feared even weeks ago, according to surveyors aboard a National Oceanic and Atmospheric Administration research vessel. This coastal ribbon of microscopic algae, up to 40 miles wide and 650 feet deep in places, is flourishing amid unusually warm Pacific Ocean temperatures. It now stretches from at ...

A toxic algae outbreak that snaked more than 600 miles down the Ohio River past four states is forcing water utilities to reassess the threat from harmful algal blooms that are popping up increasingly around the nation. Treatment plant operators and researchers along the river were surprised by the large bloom and said it should be a warning to cities that get their water supply from lakes, ...

The Pennsylvania and West Virginia Departments of Environmental Protection have begun sampling and monitoring ponds and streams in the Dunkard Creek area after sampling found golden algae in a privately owned pond in Greene County, Pennsylvania. Golden algae was determined to be the cause of a fish kill in Dunkard Creek in the fall of ...

The Department of Environmental Protection today released a work plan outlining intensive efforts to continue studying and sampling dozens of locations in the Susquehanna River basin throughout 2013. DEP's ongoing efforts include analysis of water quality, water flow, sediment, pesticides, hormones, invertebrates, fish tissue and other areas of study. Portions of the study will focus on areas of ...

A method to detect contaminants in municipal water supplies has undergone further refinements by two Oak Ridge National Laboratory researchers whose findings are published on line in Water Environment Research. The new work demonstrates that the technology that uses algae as sentinels has broader applications than previously reported, according to authors Miguel Rodriguez Jr. and Elias Greenbaum ...

Test results of water samples taken from the Anacostia River show that a black substance that has plagued a portion of the river since mid-August is a rare algal bloom, the U. S. Environmental Protection Agency announced today. Initial testing by biologists from EPA and the Maryland Department of the Environment ruled out that the discoloration was a petroleum product or other hazardous ...

Improving local water quality could mitigate the damaging effects of rising CO2 on marine ecosystems, new research suggests. Scientists in Australia found that nitrogen pollution in seawater, when acting in combination with heightened CO2 concentrations, had a significant effect on the growth of turfing algae, which displace kelp forest ecosystems. In today’s world, pressures on ...

Petrochemical lubricants have toxic effects on Antarctic seafloor ecosystems even after five years of degradation, a new study suggests. Examining the impacts of a standard lubricant and one marketed as biodegradable, the researchers were able to show that algae, which form the basis of the food chain, remained affected even after five years. Furthermore, the biodegradable lubricant appeared to ...
