1. This event was streamed live with a Google Hangout on Air from the University of Washington's IGERT Program on Ocean Change, Winter 2014 Seminar Series.

    Dr. Brian Polagye from UW Mechanical Engineering will speak on, Marine renewable energy and the environment: Progress and challenges.

    Dr. Polagye's research focuses on responsibly harnessing the kinetic energy in moving water. In particular, he is developing a better understanding of the practically recoverable resource from tidal streams through numerical modeling and field measurements. In-stream energy extraction is numerically modeled over a variety of scales, from an entire estuary down to a single device. At the estuarine scale, kinetic power extraction leads to a number of far-field effects, including changes to the tidal range, volume flow rate, and power dissipation. Each of these effects has important environmental, social, and economic consequences for in-stream developments. At the device scale, a better understanding of wake mixing is needed to establish rules for device spacing. This is critical because, unlike wind energy, the tidal resource is highly localized and compact arrays are required to efficiently utilize the available resource. The second research thrust uses field measurements to better characterize tidal energy sites and device performance. This is initially centered on velocity measurements using both shipboard and bottom-mounted ADCPs (acoustic Doppler current profilers) in Admiralty Inlet, Puget Sound. A key goal is to develop "device-neutral" site characterization methodologies to describe aspects of the in-stream resource (intensity, direction, turbulence, etc.). He is also involved in the development of cost-effective instrumentation packages to characterize the physical and biological environment at potential in-stream energy sites.

  2. This event was streamed live with a Google Hangout on Air from the University of Washington's IGERT Program on Ocean Change, Winter 2014 Seminar Series.

    Washington State Sen. Ranker spoke on, Science, policy, politics, and reality.

    Sen. Ranker serves the 40th District for Orcas Island, Washington where he lives with his wife and daughter while his son proudly serves in the U.S. Navy. Kevin is an avid runner, sailor, paddler, fisherman and surfer.

    As a Washington State Senator, Kevin has advanced key legislation focused on climate, energy, coastal and marine management, transportation, agriculture and equal rights. Legislative highlights include the sponsorship and co-sponsorship of comprehensive marine management, oil spill response and preparedness efforts and landmark legislation making Washington the seventh state to recognize full marriage equality.

    Previous to the Senate, Kevin served as a San Juan County Commissioner and was a Senior Fellow at the Ocean Foundation. In 2011, he received a White House appointment to serve as an Advisor to President Obama’s National Ocean Council. He is also the current Vice President of PNWER (Pacific Northwest Economic Region) a partnership of ten states and Canadian provinces that works to increase economic well-being, coordinate energy, economic and environmental strategies and enhance the competitiveness of the region.

  3. Live from the University of Washington's IGERT Program on Ocean Change Winter 2014 Seminar Series at 4pm PST on February 12, 2014.

    Dr. Andrew Rosenberg (Union of Concerned Scientists, Center for Science and Democracy) will be speaking on, "Science, Democracy and the Changing Ocean."

    The Center for Science and Democracy at the Union of Concerned Scientists was formed to advance the role of science in public policy and democratic dialogue. The Union was responding to growing concern about political polarization, partisanship, and divisive debate in our society that has pushed science to the side or treated scientific advice as just another special interest opinion. Our goal is to highlight the importance of scientific evidence as a basis for public policy. As we confront issues such as climate change, and it's evident impacts on the ocean and coasts, it is essential for scientists to play a key role in helping communities understand coming changes, push back against mis-information, and work directly with fellow citizens and policy makers to shape public public policy response.

  4. Live from the University of Washington's IGERT Program on Ocean Change Winter 2014 Seminar Series.

    Dr. Ann Bostrom (Weyerhauser Endowed Professor in Environmental Policy, University of Washington Evans School of Public Affairs) will speak on Ocean Change: Information for Action.

    Headlines like "ocean acidification worst in 300 million years" illustrate the increasing frequency and urgency of ocean acidification headlines over the last half dozen years. Comprising a tiny proportion of all headlines, they lend credence to calls for more and better science communication. Such calls have led to requirements for science communication training for faculty and graduate researchers, in ocean sciences as in other sciences. There is also a science of science communication. The science of science communication can inform the design and development of proactive communication strategies. Proactivity requires understanding what information is required for action and a research agenda to achieve those insights, but also an appreciation of conflicting action goals.
