Rising acidity in seawater damages marine ecosystems
Rising emissions of carbon dioxide from human activities are not only contributing to the warming effect of greenhouse gases in the atmosphere, they are also acidifying the world's oceans. New research examines the major ecological tipping points that occur when the concentration of dissolved carbon dioxide in seawater increases. The oceans absorb CO2 from the atmosphere where it dissolves and ...

NASA Research: Toxic algae found in 2300 US lakes
NASA has just released a new dataset that shows 2300 lakes in the US are contaminated with cyanobacteria. In warm, stagnant, and nutrient-rich (nitrogen and phosphorus) water, cyanobacteria, also known as blue-green algae, can form HABs. Some HABs are toxic, harming aquatic ecosystems, people, animals, drinking water supplies, the economy, and recreational ...

Modified plant clears up deadly water toxin
Plants may be a useful tool in clearing water of harmful toxins produced by blue-green algae, new research indicates. Some blue-green algae (cyanobacteria) — which grow in warm, nutrient-rich waters — produce toxins that can severely damage the liver or nervous system. The effects of the toxins range from a mild illness to rapid death. They can remain in water supplies after the algae have been ...

Marine life in reefs and coastal waters critically endangered
Many marine ecosystems are facing mass extinction as a result of human activity, such as habitat destruction, acidification of sea-water and overfishing. New research into the regions and species most at risk suggests that up to 90 per cent of large predatory fish stocks have disappeared, transforming complex food webs into simplified ecosystems dominated by microbes and algae. The research ...

Improving local conditions can improve ecosystem resilience to global changes
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 ecosystems ...

Algae Biomass Organization Welcomes Four New Member Companies Operating in Markets for Food, Feed, Water Treatment and Biotech Automation
The Algae Biomass Organization (ABO), the trade association for the algae industry, today announced WonderLogix; Ovivo Inc.; NBO3 Technologies, LLC; and Algenuity as its newest Silver-level members. The four innovators in algae product development, research and production are the latest to join the largest non-profit trade organization dedicated to developing algae into a sustainable source of ...

Algal bloom research award
NOAA has awarded USD543,336 for two competitive grants to better understand and manage outbreaks of Harmful Algal Blooms (HABs) which threaten public health and fisheries in Puget Sound. The grants cover the first year of multi-year projects, anticipated to cost almost USD1.5 million over the next three years. The goal of the first project is to develop a forecasting ability to identify which ...

IFCB in new Long-Term Ecological Research Site
Imaging FlowCytobot samplers (IFCBs) manufactured by McLane will be installed in a new Long Term Ecological Research (LTER) site off the Northeast coast of the United States. LTER programs focus attention on specific sites representing major ecosystem types, and undertake long-term assessments of populations, communities, and the physical environment. Dr. Heidi Sosik, Woods Hole Oceanographic ...

Air pollution modelling could help predict algal blooms
Models that predict how nitrogen from the air is deposited in the sea could be useful in predicting algal blooms. Based on the knowledge that excess nitrogen increases algal growth rates, researchers simulated nitrogen deposition in the North Sea and suggested that, using predicted weather data, it might be possible to adapt this approach to predict algal blooms. Algae populations are kept under ...

How much phosphorus pollution makes lakes unsafe for recreation?
A target level of 20 micrograms of phosphorus per litre of lake water could help keep many lakes safe for recreation by restricting the growth of harmful algal blooms, European research suggests. The scientists analysed the relationship between phosphorus levels in medium- and high-alkalinity lakes, the growth of cyanobacteria blooms and the concentrations of cyanobacteria that trigger World ...

EPA, NASA, NOAA and USGS Creating Early Warning System to Detect Harmful Algal Blooms
The U.S. Environmental Protection Agency (EPA) announced today that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies-- NASA, NOAA, and the U.S. ...

Algae: the new oil
I. Introduction A) Framing the Problem as an OpportunityRFS goals can not be met with soy and corn alone- there is not enough corn and soy in the US to meet RFS goals- current feedstocks soy, palm, canola, etc are in short supply and are too expensive for biodiesel producers- the biofuels industry is at a critical point where alternatives such as algae are neededB) The Opportunity: Algae- Algae ...

Nanoparticles interact with existing pollutants and make them more toxic
Nanoscience and nanotechnology are relatively new, but already nanoparticles made from C60 (Buckminster fullerenes) are finding potential applications in consumer products ranging from car lubricants to cosmetics and medicines. New research suggests that nanoparticles, when released into water systems, may interact with other common pollutants in aquatic environments with important consequences ...

Environmental concentrations of antibiotics are potentially damaging to aquatic life
Combinations of antibiotics have been found in high enough concentrations to pose a serious threat to aquatic ecosystems, in a recent Spanish study. Antibiotics can have toxic effects on the bacteria and algae that form the basis of aquatic ecosystems. Antibiotics are in widespread use, not only for human medical conditions, but also for increasing growth rates in livestock, in the feed of ...

DOE awards US$71m to accelerate innovative carbon capture project
The U.S. Department of Energy (DOE) has announced that Arizona Public Service (APS), Phoenix, Ariz., has been awarded $70.5 million from the American Recovery and Reinvestment Act (ARRA) to expand an existing industrial and innovative reuse carbon mitigation project. Arizona Public Service’s ongoing algae-based carbon mitigation project, previously selected via competitive solicitation, will be ...

Toledo mayor lifts water ban in northwest Ohio
A water ban that had hundreds of thousands of people in Ohio and Michigan scrambling for drinking water has been lifted, Toledo's mayor announced Monday. Mayor D. Michael Collins called the drinking water safe and lifted the ban at a Monday morning news conference. "Our water is safe," Collins said. "Families can return to normal life." Ohio's fourth-largest city warned residents not to use ...

Wetland plants involved in marsh restoration
Differences in the way wetland plants accumulate pollutants are helping researchers understand how vegetation can be used to help restore contaminated marshes. In a study by Belgian researchers, certain plants, including bulrushes, were identified as being potentially useful for locking away metal contaminants below the surface, thereby helping to reduce spread of these pollutants through food ...

New risks identified for aquatic wildlife from plastic compound
New evidence suggests that the adverse effects on aquatic ecosystems of chemical compounds used in the manufacture of plastics are greater than previously thought. The study reviewed data on five substances with known endocrine-disrupting effects on wildlife in rivers and waterways. Compounds such as bisphenol A (BPA), and the phthalates DBP, DEHP, DIDP and DINP2, are known as endocrine ...
