• Extreme weather events in Chesapeake Bay offer clues for future

    For the millions of people who live in its expansive coastal areas, Chesapeake Bay provides an important source of income and recreational enjoyment. To protect the ecosystem and the livelihood of area residents, it is important to assess how climate variability and change will affect Chesapeake Bay’s shallow water ecosystems and water quality.

  • Analyzing bedrock could help builders, planners identify safe building zones

    Research could give builders and urban planners more detailed information about how susceptible areas are to landslides and earthquakes. The researchers focused on bedrock, just beneath the soil and roots and the Earth’s surface. Bedrock is the layer at the bottom of what geologists refer to as the “critical zone” because its cracks and fractures provide pathways for air and water, which break down rock and form the soil that is an essential ingredient for all living organisms.

  • PNNL to help DHS address critical infrastructure vulnerabilities

    The Department of Energy’s Pacific Northwest National Laboratory (PNNL) has been named a supporting laboratory to the National Infrastructure Simulation and Analysis Center (NISAC). NISAC is a Department of Homeland Security (DHS) program which addresses the potential vulnerabilities and consequences of disruption of U.S. critical infrastructure. PNNL says it will contribute advanced computer modeling and simulation capabilities to look at the dependencies, interdependencies, vulnerabilities, and complexities of important critical infrastructure sectors such as dams, water, transportation, energy, and information technology.

  • Concrete innovation makes Seattle skyscraper stable

    All coupling beams in the 1.5 million-square-foot Lincoln Square Expansion — which includes luxury condos, a hotel, dining, retail and office space in two 450-foot towers in the heart of Seattle suburb Bellevue, Washington — are made of fiber-reinforced concrete using a unique design. These concrete coupling beams span doorways and windows, helping walls with such openings in them to function as a single structural unit, while bolstering the building as a whole against earthquakes. Traditionally, coupling beams are reinforced with a labyrinth of rebar, adding a great deal of time, cost and complexity to the construction process.

  • Tsunami-prone nations should follow Japan’s new approach to coastal defenses

    Japan’s lead in implementing sea defense improvements to guard against future disasters is an important reference point for other tsunami-prone nations. In the wake of the March 2011 Fukushima disaster, Japan has drawn new engineering guidelines which have transformed Japan’s coastal defenses, and has devised new ways to keep its coastlines safe in the future. Other nations in known tsunami risk areas, however, have not yet followed suit.

  • U.K. bolsters flood defenses

    In 1953, more than 300 people died in the United Kingdom alone when heavy storms swept a high spring tide over sea defenses and across coastal towns in north-east England and Scotland. Today floods still make headlines but our ability to limit their effects has come a long way. Flooding costs the United Kingdom £2.2 billion a year in defenses and repairs, and annual spending must keep growing just to maintain present defenses. That is a massive investment, but history — and recent history at that — shows that the risk of flooding should not be underestimated.

  • 2013 attack on Metcalf, California power grid substation committed by “an insider”: DHS

    A senior DHS official last Wednesday revealed that a 2013 sniper attack on a Metcalf, California energy grid substation – which the top U.S. electrical utility regulator has called “the most significant incident of domestic terrorism involving the grid that has ever occurred” — may have been committed by someone on the inside. The attackers fired more than 100 rounds of .30-caliber rifle ammunition into the radiators of seventeen electricity transformers, which caused the radiators to leak thousands of gallons of oil, which made electronics overheat and shut down.

  • Philippines coastal areas go underwater due to sea level rise

    More than 167,000 hectares of Philippines coastland — about 0.6 percent of the country’s total area — are projected to go underwater in, especially in low-lying island communities, according to research by the University of the Philippines. Low-lying countries with an abundance of coastlines are at significant risk from rising sea levels resulting from global warming. According to data by the World Meteorological Organization, the water levels around the Philippines are rising at a rate almost three times the global average due partly to the influence of the trade winds pushing ocean currents. On average, sea levels around the world rise 3.1 centimeters every ten years. Water levels in the Philippines are projected to rise between 7.6 and 10.2 centimeters each decade.

  • Grid Security Conference focuses on information sharing among stakeholders

    More than 300 industry and federal partners are participating in the North American Electric Reliability Corporation’s (NERC) annual grid security conference, or GridSecCon, in Philadelphia, which opened on Wednesday and ends today. The conference is focusing on key cyber and physical security issues and training for enhancing the security and resiliency of the North American bulk power system. Topics of panel discussions include upgrades to NERC’s E-ISAC, cyber and physical security technology options, the transition to Version 5 of NERC’s critical infrastructure protection standards; and expectations for NERC’s third grid security exercise, GridEx III, which takes place 18-19 November.

  • Improve cybersecurity in energy delivery

    Cyber networks support many important functions within energy delivery systems, from sending data between a smart meter and utility to controlling oil or gas flow in a pipeline. However, they are vulnerable to disturbances. According to the ICS-CERT Monitor, a publication of the U.S. Department of Homeland Security, a third of the 245 reported cyber incidents in industrial control systems that happened in 2014 occurred in the energy sector. The U.S. Department of Energy (DoE) initiative awards $28.1million to a consortium of eleven universities and research organizations, with the goal of improving computer/communication networks for energy delivery systems like power grids and pipelines.

  • Protecting the U.S. power grid from cyberattacks

    In the first half of Fiscal Year 2015, the Industrial Control Systems Cyber Emergency Response Team (ICS-CERT), part of the Department of Homeland Security, responded to 108 cyber incidents impacting critical infrastructure in the United States. As in previous years, the energy sector led all others with the most reported incidents. Researchers from Florida International University’s (FIU) College of Engineering and Computing have teamed up with four other universities and a utility company to help safeguard the nation’s power utilities from cyberattacks.

  • U Warwick, U.K. National Grid expand £1.5 million partnership

    Last week the University of Warwick and the U.K. National Grid have signed a Memorandum of Understanding (MoU) to extend the strategic alliance they have operated for last two years. To date that alliance has engaged in over £1.5 million worth of research and student scholarships in areas such as electricity transmission asset management, gas transmission, micro-tunneling, and cyber security.

  • Sea level rise dooms Miami, New Orleans

    Say goodbye to Miami and New Orleans. No matter what we do to curb global warming, these and other beloved U.S. cities will sink below rising seas, according to a new study. “In our analysis, a lot of cities have futures that depend on our carbon choices but some appear to be already lost,” says one of the study’s authors. “And it is hard to imagine how we could defend Miami in the long run.” An online tool shows which U.S. cities may face “lock-in dates beyond which the cumulative effects of carbon emissions likely commit them to long-term sea-level rise that could submerge land under more than half of the city’s population,” said the study.

  • NSF awards $74.5 million to 257 interdisciplinary cybersecurity research projects

    The NSF the other day announced the awarding $74.5 million in research grants through the NSF Secure and Trustworthy Cyberspace (SaTC) program. In total, the SaTC investments include a portfolio of 257 new projects to researchers in thirty-seven states. The largest, multi-institutional awards include research better to understand and offer reliability to new forms of digital currency known as cryptocurrencies, which use encryption for security; invent new technology to broadly scan large swaths of the Internet and automate the detection and patching of vulnerabilities; and establish the “science of censorship resistance” by developing accurate models of the capabilities of censors.

  • Cyber vulnerability of civil nuclear facilities underestimated

    The risk of a serious cyberattack on civil nuclear infrastructure is growing, as facilities become ever more reliant on digital systems and make increasing use of commercial off-the-shelf software, according to a new report. The report finds that the trend to digitization, when combined with a lack of executive-level awareness of the risks involved, means that nuclear plant personnel may not realize the full extent of their cyber vulnerability and are thus inadequately prepared to deal with potential attacks.
