NOAA developes first underwater detection system of harmful algae toxins

Researchers from NOAA’s National Centers for Coastal Ocean Science and the Monterey Bay Aquarium Research Institute (MBARI) have carried out the first remote detection of a harmful algal species and its toxin.

Harmful algae blooms (HABs) and marine biotoxins impact the whole marine food web and the human endeavors associated with living marine resources. HAB events can occur in relatively small areas, many of them have origins in far off-shore oceanic environments. It is believed that climate change is expected to exacerbate HAB events, due to changes in water temperature and ocean circulation, which are influenced by climate. Because of the scale of these HAB events, NOAA developed a HAP Operational Forecast System, used to develop predictions of the transport and potential development of harmful algae conditions in the Gulf of Mexico. This remote detection system is a major milestone in NOAA’s effort to monitor the type and toxicity of harmful algal blooms (HABs) and forecast their development. The remote detection system is called the Environmental Sample Processor, or ‘ESP.’ The processor is designed as a fully-functional underwater laboratory, allowing researchers to collect and analyze the algal cells identifying specific toxins and genetic information in order to assess the risk to humans and wildlife.

‘Copernicium’ Proposed As Name For Newly Discovered Element 112

In honor of scientist and astronomer Nicolaus Copernicus (1473-1543), the discovering team around Professor Sigurd Hofmann suggested the name „copernicium” with the element symbol “Cp” for the new element 112, discovered at the GSI Helmholtzzentrum für Schwerionenforschung (Center for Heavy Ion Research) in Darmstadt. It was Copernicus who discovered that the Earth orbits the Sun, thus paving the way for our modern view of the world. Thirteen years ago, element 112 was discovered by an international team of scientists at the GSI accelerator facility.

Increasing Antarctic Sea Ice Extent Linked To Ozone Hole

Increased growth in Antarctic sea ice during the past 30 years is a result of changing weather patterns caused by the ozone hole, according to new research.Reporting in the journal Geophysical Research Letters, scientists from British Antarctic Survey (BAS) and NASA say that while there has been a dramatic loss of Arctic sea ice, Antarctic sea ice has increased by a small amount as a result of the ozone hole delaying the impact of greenhouse gas increases on the climate of the continent.

Sea ice plays a key role in the global environment – reflecting heat from the sun and providing a habitat for marine life. At both poles sea ice cover is at its minimum during summer. However, during the winter freeze in Antarctica this ice cover expands to an area roughly twice the size of Europe. Ranging in thickness from less than a metre to several metres, the ice insulates the warm ocean from the frigid atmosphere above. Satellite images show that since the 1970s the extent of Antarctic sea ice has increased at a rate of 100,000 square kilometres a decade.The new research helps explain why observed changes in the amount of sea-ice cover are so different in both polar regions.

Solar Power: New SunCatcher Power System Ready For Commercial Production In 2010

Stirling Energy Systems (SES) and Tessera Solar recently unveiled four newly designed solar power collection dishes at Sandia National Laboratories’ National Solar Thermal Test Facility (NSTTF). Called SunCatchers™, the new dishes have a refined design that will be used in commercial-scale deployments of the units beginning in 2010.
