  • EarthquakesNew map outlines landslide risks in western Oregon

    Landslides are already a serious geologic hazard for western Oregon. During an earthquake, however, lateral ground forces can be as high as half the force of gravity. The Coast Range is of special concern because it will be the closest part of the state to the actual subduction zone earthquake, and will experience the greatest shaking and ground movement. New landslide maps have been developed that will help the Oregon Department of Transportation determine which coastal roads and bridges in Oregon are most likely to be usable following a major subduction zone earthquake that is expected in the future of the Pacific Northwest.

  • Coastal infrastructureIPCC sea-level rise scenarios insufficient for high-risk coastal areas management

    The sea-level rise scenarios of the Intergovernmental Panel on Climate Change (IPCC) do not necessarily provide the right information for high-risk coastal decision-making and management, according to new research. Researchers warn that the IPCC scenarios are often inappropriate or incomplete for the management of high-risk coastal areas as they exclude the potential for extreme sea-level rises. This missing information is also crucial for a number of policy processes, such as discussions by G7 countries to establish climate insurance policies and allocations of adaptation funding by the Green Climate Funds.

  • CybersecurityObama’s cybersecurity initiative: a start but businesses – and individuals – need to do more

    By Frank J Cilluffo and Sharon L Cardash

    The linchpin of President Obama’s recently launched cybersecurity initiative is to encourage the private sector to share information to better defend against cyberattacks. Yet U.S. companies have historically been wary of openly talking about their cybersecurity efforts with competitors and with government — for good reason. Many businesses fear that sharing threat-related information could expose them to liability and litigation, undermine shareholder or consumer confidence, or introduce the potential for leaks of proprietary information. For some companies, Edward Snowden’s revelations of sweeping government surveillance programs have reinforced the impulse to hold corporate cards close to the vest. Yet on the heels of a deluge of high-profile cyberattacks and breaches against numerous U.S. companies, we may finally have reached a tipping point, where potential harm to reputation and revenue now outweighs the downside of disclosure from a corporate perspective. Obama’s executive order is thus a spur to get the ball rolling but, frankly, there is a limit to what government alone can (and should) do in this area. Changes in attitudes and behaviors are needed across the board, right down to families and individuals.

  • Coastal floodingA 2-year spike in sea level along NE North America

    Sea levels from New York to Newfoundland jumped up about four inches in 2009 and 2010 because ocean circulation changed, new research has found. Independent of any hurricanes or winter storms, the event – which stands out in its time extent as well as its spatial extent — caused flooding along the northeast coast of North America. Some of the sea level rise and the resulting flooding extended as far south as Cape Hatteras. The spike was the result of a change in the ocean’s Atlantic Meridional Overturning Circulation and also a change in part of the climate system known as the North Atlantic Oscillation. The researchers found that at the current rate that atmospheric carbon dioxide is increasing, such extreme events are likely to occur more frequently. The research also confirmed that, as others have reported, sea level has been gradually rising since the 1920s and that there is some year-to-year variation.

  • Food securityOcean acidification threatens U.S. coastal communities

    Coastal communities in fifteen states that depend on the $1 billion shelled mollusk industry (primarily oysters and clams) are at long-term economic risk from the increasing threat of ocean acidification, a new report concludes. The Pacific Northwest has been the most frequently cited region with vulnerable shellfish populations, the authors say, but the report notes that newly identified areas of risk from acidification range from Maine to the Chesapeake Bay, to the bayous of Louisiana.

  • Infrastructure protectionConcrete solutions to aging, structurally deficient bridges

    According to the Pennsylvania Department of Transportation (PennDOT), the state leads the nation in the number of bridges classified as “structurally deficient.” This is probably not a surprise to most residents who have done any driving throughout the commonwealth. The state’s more than 25,000 state-owned bridges are aging — their average age is over fifty years — and in need of repair. Penn State civil engineering faculty are researching methods for enhancing the maintenance and durability of civil infrastructure — including anything made of concrete, from bridges to roads to buildings.

  • Infrastructure protectionWireless sensors keep public infrastructure safe

    European researchers have developed a wireless sensor system to monitor the safety of large infrastructure such as bridges – but also historic monuments. The new system will potentially save lives as the structure ages, and it will reducing construction cost of new infrastructure.

  • Infrastructure protectionScanning technology detects early signs of potholes

    Researchers are developing smart scanning technology using existing cameras to detect the early signs of potholes and determine their severity. a computer vision algorithm, combined with 2D and 3D scanners on a pavement monitoring vehicle, can examine the road with accuracy at traffic speed during day or night. The system works by detecting different textures of the road to identify raveling and distinguishes it from shadows and blemishes such as tire marks, oil spills, and recent pothole repairs.

  • Coastal infrastructureBay of Bengal: Rising seas to force 13 million to evacuate to higher grounds

    Within the next thirty years, a substantial area — called the Sundarbans — in the Bay of Bengal will be underwater as a result of climate change-induced rising sea levels. The roughly thirteen million people living in the region, which consists of approximately 200 delta islands in India and Bangladesh, will be forced to abandon their homes, making their displacement the largest exodus in modern history. The migration of eight million Bangladeshis and five million Indians inland will create the largest group of “climate refugees,” challenging social, agricultural, logistical, and governmental structures.

  • ResilienceMore resilient mass transit to improve Chicago emergency evacuation system

    A group of Argonne Lab researchers will be studying methods and creating tools for building more resilient mass transit systems to evacuate major cities under a $2.9 million grant announced today by the U.S. Department of Transportation’s Federal Transit Administration. The project will bring together researchers from the Department of Energy’s Argonne National Laboratory with Chicago’s Pace Suburban Bus and Metra Commuter Rail Service to investigate ways to improve the detection, analysis, and response to emergencies, and how best to evacuate the city in a major emergency.

  • Infrastructure protectionU.S. contemplates responses to a cyber-Pearl Harbor attack on critical infrastructure

    Cybersecurity experts often contemplate how U.S. security agencies would react to a cyber-9/11 or a digital Pearl Harbor, in which a computer attack would unplug the power grid, disable communications lines, empty bank accounts, and result in loss of life. “Ultimately, it absolutely could happen,” says one expert. “Yeah, that thought keeps me up at night, in terms of what portion of our critical infrastructure could be really brought to its knees.”

  • Sensor networkWireless sensors transform real-time monitoring infrastructure

    Small wireless computing devices, ranging from the size of a matchbox to the size of a dime, are going to change the way Florida monitors its water quality, sea level rise, hurricanes, agriculture, aquaculture, and even its aging senior population. These sensing devices can collect information about the surrounding environment and transmit that information to cloud-based computing systems that store, analyze, and present that information to educators, researchers, and decision-makers. Deployable at massive scales, the technology represents a paradigm shift in how our world is observed and managed.

    A new report by NASA and Columbia University researchers details significant future increases in temperature, precipitation, and sea level in the New York metropolitan area. The report aims to increase current and future resiliency of the communities, citywide systems, and infrastructure in the New York metropolitan region to a range of climate risks. “Climate change research isn’t just something for the future,” said the NASA scientist who chaired the panel which produced the report. “It’s affecting how key policy decisions are being made now.

  • CybersecurityObama signs cybersecurity executive order, promotes information-sharing hubs

    President Barack Obama, at last week’s White House Summit on Cybersecurity and Consumer Protection, reiterated the need for more companies to collaborate with each other as well as with the federal government to develop cybersecurity solutions that protect consumer privacy while keeping hackers out of network systems.One strategy Obama encouraged in his speech was the creation of information-sharing groups, called hubs, built around vertical industry sectors.

  • Infrastructure protectionImproving security monitoring of energy industry networked control systems

    There are a number of useful products on the market for monitoring enterprise networks for possible security events, but they tend to be imperfect fits for the unusual requirements of control system networks. A network monitoring solution that is tailored to the needs of control systems would reduce security blind spots. The National Cybersecurity Center of Excellence (NCCoE) is seeking collaborators on an effort to help energy companies improve the security of the networked technologies they rely upon to control the generation, transmission and distribution of power.
